VEZZOLI, LUIGINA, et CLAUDIA PRINCIPE. « MONTE AMIATA VOLCANO (TUSCANY, ITALY) IN THE HISTORY OF VOLCANOLOGY, PART 1 : ITS ROLE IN THE DEBATES ON EXTINCT VOLCANOES, SOURCES OF MAGMA, AND ERUPTIVE MECHANISMS (1733–1935) ».

Résumé :
A review of the main contributions to the scientific literature between the eighteenth and twentieth centuries concerning the geology and volcanology of Monte Amiata volcano (Tuscany, central Italy) is presented. Monte Amiata, and the nearby volcano of Radicofani, are of great interest for the history of volcanology because they have the primacy of being the first to be recognized of volcanic origin in a region (Tuscany) which was not volcanically active, thirty years before Guettard's studies on the Auvergne region in France. Indeed, the Florentine botanist Pier Antonio Micheli identified as extinct volcanoes Radicofani in 1722 and Monte Amiata in 1733. Moreover, the merit of Micheli's work resides in interpreting Monte Amiata as an extinct volcano despite the absence of a conventional cone-shaped volcano morphology, and in his recognizing its rocks as lavas despite their marked differences to those produced by the known active volcanoes of its times, such as the iconic Vesuvius. During the eighteenth century and until the first half of the nineteenth century, Monte Amiata was a destination for scientific journeys by Tuscan and foreign scholars (e.g. Micheli, Baldassarri, Arduino, Fortis, Ferber, Dolomieu, Santi, Repetti, Hoffmann). In addition, its rocks were part of important collections throughout Europe visited by illustrious mineralogists. Furthermore, samples from Monte Amiata were used to illustrate the general discussions on the nature and origin of rocks such as basalt and granite. In the nineteenth century, Monte Amiata was included in the lists of known volcanoes recorded in the early treatises on volcanology made by Scrope, Daubeny, and Hoffmann, and its ‘trachyte’ was the subject of early essays on microscope petrography and chemical analysis of rocks, performed by vom Rath, Rosenbusch, Williams, Lacroix, and Washington. Between the end of the nineteenth century and the first quarter of the twentieth century, the volcano geologists of the Comitato Geologico Italiano, especially Verri, Lotti, and Sabatini, carried out field-surveys on Monte Amiata resulting in geological maps and volcano-stratigraphies. Moreover, modern petrographic (Novarese, Artini, Rodolico) and geographical (Dainelli and Olinto Marinelli) scientific studies were carried out on this volcano. Nevertheless, up to the middle part of the twentieth century, the major interest in Monte Amiata was related not to its volcanological aspects but to its natural resources: drinking waters, diatomaceous earths, earth pigments, and mercury ore-minerals.

Résumé :
At the foothillof Monte Amiata volcano (southern Tuscany, Italy), small extinct lake basins of late Pleistocene age are documented. These lake basins were characterized by the deposition of two very different types of sediment: a) derived from the authigenic precipitation of iron oxides (goethite) and exploited as earth pigments; b) biogenic siliceous sediment composed of fossil diatoms and named diatomaceous earth or diatomite. The lacustrine sediments of Mount Amiata volcano were widely exploited for various applications since ancient times. Literary documents begin in the 16th century, with the descriptions of Cesalpino, Gesner, Agricola, and Imperato. Specific references to the diatomites of Monte Amiata are quoted in the 17th century by Boccone and Bonanno. The quarrying activity was described by Micheli in 1733. During the 18th and 19th centuries, the diatomaceous earths of Monte Amiata are part of the important geological collections of Micheli, Targioni Tozzetti, Baldassarri, Campani, and Tommi. A particular significance has the collection of botanic and ichthyologic fossils collected by Ezio Tongiorgi, and now preserved in the Museum of Natural History of the University of Pisa sited at the Charterhouse of Pisa in the Calci village. These paleontological samples preserve the biological and physical testimonies of the environmental and climatic changes of the late Pleistocene and are now particularly valuable because they are the only remaining evidence of the diatomaceous lacustrine deposits of the paleo-lakes of Monte Amiata. For these reasons, they represent geological materials with a fundamental cultural value.

Résumé :
ABSTRACT Among the artist’s iron-based natural earth pigments, the so-called terra di Siena (raw sienna), terra di Siena bruciata (burnt sienna) and terra d’ombra (umber) have been among the yellow-brown and reddish-brown earth pigments most widely used by Italian and European painters since the Renaissance. We present the history of discovery, designation, and production of these famous pigments, their geological, lithological, and geochemical characterization, and the recognition of their genesis and places of origin, based on new geological field surveys, and on the critical analysis of textual documents and rock sample collections assembled during the eighteenth and nineteenth centuries. In particular, the terra di Siena earth pigment exclusively originated at, and was extracted from, late Pleistocene paleo-lake basins surrounding the Monte Amiata volcano. This earth pigment consists of primarily lacustrine sediments composed of hydrated iron oxide (limonite/goethite) produced by biochemical authigenic precipitation from fresh waters rich in metal solutes.

Résumé :
As a man-induced disturbance of forest ecosystems, thinning may affect biodiversity and other related ecological functions including fungal dynamics. In this context, a multidisciplinary EU-Life project was established in 2014 to evaluate the application of selective thinning in two Pinus nigra plantations areas of the Apennines (Monte Amiata and Pratomagno, Tuscany, Italy). Selective thinning had the aim to improve stands stability and growth rates, taking also into account the various components of soil biodiversity (flora, fungi, mesofauna, nematodes, microarthropods and bacteria). Here we present mushroom fruiting patterns previous to treatment in 2014 and the effect following the application of forest management (selective thinning and traditional thinning from below) in 2018. Boxplots were used to graphically represent intra and inter annual variations in species richness and abundance, while Principal Coordinates Analyses and multi-response permutation procedures based on Bray-Curtis dissimilarity matrix were applied to evaluate turnover in species composition before the management and after 4 years. A significant reduction of fungal richness and abundance after 4 years thinning impact was lacking in both study areas, testifying a certain degree of resistance and/or resilience of mushroom fruiting to forest management-related anthropogenic disturbance. Considering each study site separately, Monte Amiata and Pratomagno did not show one uniform trend but differed significantly in their response to management: while in Pratomagno relevant inter-annual differences were present only in a few cases, an underlining significant variation both for species richness and abundance was registered in Monte Amiata for all treatment types among years (inter-annual variation) but not within each year (intra-annual variation). Only in Pratomagno turnover in species composition in selective thinning differed somewhat from the traditional treatment in 2018, showing that a process is underlying but still potentially masked by other variables. Due to the nature of macrofungi, a longer study period (more than 4 years post treatment impact) as well as the application of a more intense forest management, could be necessary to highlight and disentangle any possible trends in fungal fruiting in artificial stands

Résumé :
Shear Wave Splitting is an application of seismic wave to analyse the anisotropy level of a certain medium. Generally, shear wave propagation through a rock formation will be polarized (φ) into two parts especially when the medium structures are different, such as fracture. The polarized shear wave which is perpendicular to fracture will propagate slower than the wave that propagates parallel to the fracture. The delay time (δt) of both wave is proportional with the fracture intensity along the wave propagation from the source to the station. The description regarding fracture orientation can be obtained by analysing both Shear Wave Splitting parameters (φ and δt), and this information is adequately important in geothermal exploration or exploitation phase at Mt. Amiata. Based on the result of this research, the micro earthquake source is focused on the east to the south area and spread along 3 earthquake stations. The existence of micro earthquake source is mainly focused at the depth of 1 to 4 km. In addition, the polarization direction of each earthquake station at the geological map shows a dominant fracture orientation consistently at NW-SE. All of the three stations also show that the polarization direction is integrated to the local fault existence in the subsurface. Furthermore, the research shows that the high intensity fracture distribution occurred at MCIV station area in the southern part of research location. Meanwhile, the low intensity fracture distribution occurred at ARCI and SACS station area in the western and the eastern part of research location. The high value of fracture intensity accompanied by the high amount of structure intensity, strengthen the prediction of the high anisotropy existence which potentially tends to the high permeability presence at the area.Keywords: shear wave splitting, anisotropy, fracture, geothermal, polarization direction, fracture intensity.

Résumé :
In the present study, mercury (Hg) concentrations were investigated in lichens (Flavoparmelia caperata (L.) Hale, Parmelia saxatilis (L.) Ach., and Xanthoria parietina (L.) Th.Fr.) collected in the surrounding of the dismissed Abbadia San Salvatore Hg mine (Monte Amiata district, Italy). Results were integrated with Hg concentrations in tree barks and literature data of gaseous Hg levels determined by passive air samplers (PASs) in the same area. The ultimate goal was to compare results obtained by the three monitoring techniques to evaluate potential mismatches. Lichens displayed 180–3600 ng/g Hg, and Hg concentrations decreased exponentially with distance from the mine. Mercury concentration was lower than in Pinus nigra barks at the same site. There was a moderate correlation between Hg in lichen and Hg in bark, suggesting similar mechanisms of Hg uptake and residence times. However, correlation with published gaseous Hg concentrations (PASs) was moderate at best (Kendall Tau = 0.4–0.5, p > 0.05). The differences occurred because a) PASs collected gaseous Hg, whereas lichens and barks also picked up particulate Hg, and b) lichens and bark had a dynamic exchange with the atmosphere. Lichen, bark, and PAS outline different and complementary aspects of airborne Hg content and efficient monitoring programs in contaminated areas would benefit from the integration of data from different techniques.

Résumé :
<abstract> <p>The environmental impact of mining and smelting in the world-class Monte Amiata mercury (Hg) ore field has long been studied, before and after the final closure in 1982. A first summary was presented in 2015. With this contribution, we review the studies conducted in the last eight years. The most significant results include ⅰ) Hg-isotope characterization of primary ore (cinnabar), smelting waste (calcines), soil, fish and stream sediments; ⅱ) analysis of the interplay between geomorphological evolution, fluvial dynamics and Hg distribution in the Paglia River catchment, which drains the main mining areas; ⅲ) an improved quantification of the Hg loads discharged to the Mediterranean Sea; ⅳ) the use of biomonitors to reveal the dispersion of Hg; ⅴ) new detailed surveys, including innovative techniques, of Hg distribution in air; ⅵ) specific investigations to support the ongoing reclamation at Abbadia San Salvatore, the main mining and smelting center of the district, and ⅶ) the assessment of the variability of Hg distribution in air, water and soil from the reclaimed Siele mine. Despite these progresses, there are further steps to be conducted to achieve optimal management of the wide contamination evidenced in this district. It is now fully clear that the diffuse character of contamination results in unfeasible hypotheses for total remediation. Therefore, the goal is that of a sustainable coexistence between contamination and human activities. This goal may involve the following activities: a) implementation of GIS-based contamination maps as a direct operational instrument for local authorities to tune up specific limitations and regulations of human activities (e.g., fishing, instream quarrying and wildfire management); b) mitigation measures such as increasing the vegetal cover of river banks to limit erosion and runoff, and c) continuous monitoring of air, water and soil contamination, including transfer to the food chain.</p> </abstract>

Résumé :
Geothermal energy is a clean resource, which could significantly contribute to the reduction of greenhouse and other gas emissions by replacing fossil fuels for power generation. In many geothermal sites, the resource contains substantial Non-Condensable Gases (NCGs: CO2 and contaminants), whose emissions can be limited to developing power plant schemes suitable for complete resource reinjection. Organic Rankine or other closed-loop cycles are definitely favored in this light. This work investigates a solution for complete NCG reinjection in the liquid-dominated reservoir conditions typical of the Monte Amiata area (Italy), referring to the specific site of Torre Alfina (IT) which presents a specific attractiveness because of its high pressurization. The solution considered avoids flashing the resource and thus presents an appealing environmental performance. The power plant models include energy and exergy balances, as well as exergo-environmental analysis. The overall environmental performance is evaluated by a simplified (preliminary) Life Cycle Analysis (LCA). Different solutions are compared, considering the possibility of sub- or super-critical power cycles.

Résumé :
The Mediterranean Sea is characterized by a marked mercury (Hg) geochemical anomaly, arising in part from large Hg deposits. Mercury mass loads discharged from the Monte Amiata mining district (Central Italy) to the Mediterranean Sea through the Paglia–Tiber River system were estimated. Data from two seasons showed that up to 40 kg year−1 of Hg are drained to Tiber River and finally to the Mediterranean Sea. The mercury mass loads varied in different seasons, from 3 mg day−1 in the upper section of Paglia River in November to 42 g day−1 before the confluence with Tiber River in June. Along Tiber River, up to 15 ng L−1 of the total Hg found at a site after Rome showed that Hg can be discharged to the sea. The Alviano reservoir along Tiber River acts as a temporary trap for Hg-rich particulate, while dam operations may promote Hg release (up to 223 g day−1). The combination of hydrologic factors controlling Hg transport, the torrential regime in the upper catchment of Paglia River, the waterway steepness, together with Hg-contaminated legacy sediments in the Paglia River floodplain, make the Paglia–Tiber River system a long-lasting intermittent source of Hg to Tiber River and the Mediterranean Sea.

Résumé :
The research presented here seeks to describe the impact of wild boar to a natural truffle ground of <em>Tuber aestivum </em>Vittad. on Monte Amiata (Tuscany – Italy). Pedoclimatic analyses indicated that the selected area could be considered suitable for the truffle production. Then classification of the vegetation of a <em>Quercus cerris </em>forest was carried out exploring the possibility of the BACI (Before-After-Control-Impact) sampling design. Finally 10 plots were selected, half of which have been fenced. For the first time the impact of wild boar was evaluated by estimating the surface area turned over by its activity. Moreover in each plot the number and weight of summer truffles was performed every 10 days during the fruiting period (June-November 2006-2008). The hypothesis that the presence of <em>Sus scrofa </em>has a strong negative influence on truffle harvesting has been amply confirmed by the data presented here, given the large increase of fruiting bodies of the summer truffle collected in the fenced plots. Consequently the destructive behaviour of the wild boar imply not only an ecological but also an economic damage in areas in which non-wood forest products are an important source of income.

Résumé :
Abstract Carlin-type gold deposits in northern Nevada are inferred to overlie concealed late Eocene plutons, which are increasingly thought to have provided magmatic input to the meteoric water-dominated fluids from which the gold was precipitated. The Larderello, Monte Amiata, and Latera geothermal systems in the Northern Apennines of southern Tuscany and northern Latium, central Italy, may represent Pliocene to present-day analogues because of their demonstrated association with subsurface plutons and jasperoid-hosted antimony-gold mineralization. The plutons, which at depths of &gt;5–7 km remain at least partially molten, continue to supply heat and magmatic fluids to the meteoric water-dominated geothermal systems. Formerly mined antimony deposits of Pliocene or younger age are exposed on the peripheries of the CO2 ± H2S-emitting geothermal systems, and antimony sulfides are still actively precipitating. Stibnite and submicroscopic gold in disseminated pyrite, along with Au/Ag of &lt;0.5 and anomalous As, Hg, Tl, and Ba values, accompanied jasperoid formation in the Northern Apennines systems. Carlin-type mineralization in northern Nevada and the antimony-gold mineralization in the Northern Apennines are hosted by permeable carbonate rocks, particularly stratabound breccias, where they are intersected by steep normal or oblique-slip faults and confined beneath tectonically emplaced hydrologic seals. The Northern Apennines antimony-gold mineralization formed at shallow, epithermal depths, like that recently recognized in the southern Carlin trend of northern Nevada. Although underexplored, the Northern Apennines gold prospects are unlikely to ever attain the giant status of the Carlin-type deposits in northern Nevada, probably because of lower magmatic fertility (ilmenite-series rather than magnetite-series magmatism) and host-rock receptivity (less reactive iron). Nevertheless, shallow carbonate-rock aquifers within high-temperature, intrusion-related geothermal systems, be they extinct or still active, may be prospective for Carlin-style gold deposits.

Résumé :
Bede entered Wearmouth–Jarrow at the age of seven and thereafter, he tells us at the conclusion of his Historia ecclesiastica, spent all his life ‘applying myself entirely to the study of the Scriptures’. He goes on, ‘From the time I became a priest until the fifty-ninth year of my life I have made it my business, for my own benefit and that of my brothers, to make brief extracts from the works of the venerable fathers on the holy scriptures, or to add notes of my own to clarify their sense and interpretation.’ Bede's modest remarks preface an impressive list of his own works, which includes commentaries on Genesis, I Samuel, Kings, Proverbs, the Prophets, Mark, Luke, Acts and Revelation, and many other exegetical, didactic and historical volumes. Installed at Jarrow from about 679 until his death in 735, he contributed more than anyone to the intellectual distinction of early-eighth-century Northumbria. At the same time, the twin house of Wearmouth–Jarrow was winning lasting renown for the products of its scriptorium (or scriptoria). Not least among these were the three great Vulgate bible pandects which Abbot Ceolfrith caused to be made, an achievement celebrated by the chroniclers of the house, who included Bede himself. One of these pandects, which we know today as the Codex Amiatinus, was dispatched to St Peter's in Rome in 716, then spent more than 900 years at Monte Amiata in the Appenines, and is now in Florence (Biblioteca Medicea Laurenziana, Amiatino 1). The other two were for use in the Wearmouth and Jarrow churches. One of these has been lost without trace, but the second survived in the cathedral priory of Worcester until the sixteenth century, when an entrepreneurial Nottinghamshire family made use of some of its torn-out leaves as document wrappers. Twelve of these, with some fragments of a thirteenth, are now in the British Library under three different shelfmarks (Loan 81, Add. 37777 and Add. 45025).

Résumé :
Abstract Purpose The extensive Hg contamination in soil and sediments occurring along the Paglia River (Central Italy) is the result of the interplay between the geomorphological changes of the river and anthropic activities, primarily associated to the exploitation of Hg-deposits in "The Monte Amiata mining district" (MAMD). The present study determines the implications of the morphological changes that occurred along the Paglia River in the last 200 years on the distribution of Hg along the floodplain and riverbed, which today represent one of the main Hg-reservoirs in the MAMD. Materials and methods The temporal changes of the Paglia riverbed and the extent of its alluvial deposits were reconstructed by a GIS-based analysis of the available maps and aerial photos. The Hg-concentration in soil and sediment samples, collected along five transects transverse to the Paglia River channel, was determined by ICP-MS. Results and discussion Samples along the investigated Paglia River segment typically show Hg-contents exceeding the Italian threshold for residential and public green soil use (1 mg kg−1). The distribution of Hg in the Paglia floodplain results from the combination of exceedance of sediment yield to the river during mining activities, that fed the floodplain with large amounts of Hg-contaminated sediments during its braided stage about 100 years ago, and the morphological changes of the river, that led to the evolution from a braided to the present-day single channel river. The magnitude of the extension of Hg-contamination, the river geomorphologic changes, and the processes of transport, deposition, and re-suspension did not allow a natural “clean up” of the river system, which shows a low resilience. Under high flow conditions, and especially in coincidence with intense rain events, large amounts of Hg stored in the overbank sediments are mobilized and redistributed, contributing to make the floodplain a secondary Hg-source. Extreme weather events, expected to intensify as a consequence of climate change, will contribute to the recurrent distribution of Hg-contaminated legacy sediments in the floodplain and along the Paglia river course. Conclusion From a water/land management perspective, the variability of the river flow, associated with an increase of extreme flood events driven by climate change, will affect the distribution of Hg-contaminated particles in the Paglia River, contributing to the Hg input into the Mediterranean Sea in the future.

Résumé :
O estudo foi realizado em duas áreas antropizadas (Fazenda Areão e Monte Olimpo) do campus “Luiz de Queiroz”, em Piracicaba, SP. Foram analisados os dados de 52 coletas em 14 armadilhas tipo McPhail distribuídas nas duas áreas. Foram coletadas 1.583 fêmeas pertencentes a 14 espécies: Anastrepha amita Zucchi, A. barbiellinii Lima, A. bistrigata Bezzi, A. daciformis Bezzi, A. distincta Greene, A. fraterculus (Wiedemann), A. grandis (Macquart), A. manihoti Lima, A. montei Lima, A. obliqua (Macquart), A. pickeli Lima, A. pseudoparallela (Loew), A. serpentina (Wiedemann) e A. sororcula Zucchi. Na Fazenda Areão, foram coletados mais espécimes (1.041) do que no Monte Olimpo (542). A média de sobreposição de nicho foi maior que o esperado ao acaso para as duas áreas, portanto, os nichos ecológicos das espécies, em grande parte, se sobrepõem. Pelo padrão de coocorrência, a segregação não foi aleatória entre dois pares de espécies: A. pseudoparallela x A. obliqua (Fazenda Areão) e A. fraterculus x A. pseudoparallela (Monte Olimpo). A segregação indicou que pode haver competição por algum recurso em cada nicho. A análise também apresentou três pares agregados: A. bistrigata x A. montei e A. fraterculus x A. barbiellinii (Fazenda Areão) e A. fraterculus x A. bistrigata (Monte Olimpo), indicando que cada par ocorre concomitantemente, sem que haja interferência na permanência das populações dessas espécies nas áreas.

Nusantara Bioscience 9: 330-337. Research described in this paper investigated the effect of fertilizer application on the growth, biomass production and nutrient accumulation of mahang (Macaranga gigantea) plant components. The experiment was carried out in a research area of the Faculty of Forestry, Mulawarman University, Samarinda, East Kalimantan. The effects of five dose levels of an NPK (16-16-16) fertilizer on the growth rate of mahang seedlings planted in field conditions were compared. The treatments consisted of a control group (with no fertilizer), and dosages of 40 g, 80 g, 120 g and 160 g per plant. Fertilization at those levels was applied twice: the first application at four weeks after the planting and the second application at 6 months after the first. Growth rates between treatments were compared over a twelve month period. The research findings revealed that as the dosages of fertilizer increased, so the growth, biomass production and nutrient accumulation in components of the plants also increased. The best growth was found in the treatment in which fertilizer was applied (twice) at a dosage of 120 g per plant; at this dose level, by twelve months of age, the stem basal diameter had reached 45.24.9 cm, stem height 219.239.1 cm, number of leaves per plant 17.31.2, and canopy diameter 246.725.0 cm. The highest production of above-ground biomass was also found in the fertilizer treatment of 120 g per plant; the largest proportion of the biomass was in the leaves, followed by the wood, and then bark. The nutrient element that had accumulated most in plants at 1 year of age was potassium, followed by phosphorus and then nitrogen. The highest nitrogen uptake of stands was found in the NPK fertilization with a dosage of 160 g per tree, while the highest phosphorus and potassium uptake was found at a fertilizer dosage of 120 g per tree. The amount of nutrients accumulated in producing one tonne of above-ground biomass increased in response to different fertilization treatments. The fertilizer treatment of 120 g per plant (applied twice; the first soon after planting and the next after 6 months) resulted in the accumulation within the 1 year old plants of 2.38 kg of nitrogen, 6.36 kg of phosporus and 17.83 kg of potassium, with an N:P:K ratio of 13.3 : 35.6 : 100. The availability of the element potassium needs special attention when this species is cultivated.

Résumé :
A preliminary magnetotelluric (MT) survey was carried out in Southern Tuscany, Italy, to delineate the resistivity structure in an area which does not belong to classic geothermal zones but is still characterized by anomalously high heat flow. The one-dimensional (1D) resistivity inversion shows a low resistivity zone characterized by high heat flow. Based on 1D resistivity information, detailed two-dimensional (2D) resistivity modelling was carried out. A reasonable 2D resistivity model was proposed for shallow depths, and was found to be in good agreement with the available geological and geophysical information on the area. The present results show a low resistivity anomaly, characterized by high heat flow. The anomaly seems to extend beyond the classic Mt. Amiata geothermal region.
