Abstract:

Die Universitätsgründung in Berlin von 1810 war verbunden mit der Übernahme des Lehrbetriebes der aufgelösten Bergakademie, die nur noch in Form des Bergeleveninstituts bzw. Bergelevenklasse für die Finanzierung der Ausbildung der Bergeleven weiter bestand, sowie mit der Übernahme des von der Bergakademie genutzten Königlichen Mineralienkabinetts der preußischen Bergverwaltung als Mineralogisches Museum der Universität. Infolge des Todes von D. L. G. Karsten im Jahre 1810 erhielt der Leipziger Physiker und Mineraloge C. S. Weiss den Lehrstuhl für Mineralogie, den er bis zu seinem Tode 1856 innehatte. Weiss entwickelte die Lehre Werners, die die Mineralogie einschließlich Geologie umfasste, in kristallographischer Hinsicht weiter, während sich später neben ihm zwei seiner Schüler anderen Teilgebieten der Mineralogie annahmen, G. Rose der speziellen Mineralogie und E. Beyrich der geologischen Paläontologie. Der Ausbau der Sammlungen durch eigene Aufsammlungen, Schenkungen und Käufe konnte in starkem Maße fortgesetzt werden, auch zunehmend in paläontologischer Hinsicht, sodass das Mineralogische Museum für das ganze Spektrum der Lehre gut bestückt war. Der streitbare Charakter von Weiss verursachte zahlreiche Reibungspunkte. <br><br> History of the Geoscience Institutes of the Natural History Museum in Berlin. Part 4 <br><br> The establishment of the University in Berlin in 1810 resulted in the adoption of the teaching of the dissolved Bergakademie and of the royal Mineralienkabinett of the Prussian mining department, which was used by the Bergakademie before it became the Mineralogical Museum of the University. The Bergakademie continued to exist only as Bergeleveninstitut or Bergelevenklasse for financing the education of the mining students. The physicist and mineralogist C. S. Weiss was offered the chair of mineralogy after the death of D. L. G. Karsten 1810; he had the position to his death in 1856. Weiss developped the crystallographic part of the science of Werner which included mineralogy and geology. Two of his pupils progressed two other parts of mineralogy, G. Rose the speciel mineralogy and E. Beyrich the geological paleontology. The enlargement of the collections continued on large scale by own collecting, donations and purchases, also more paleontological objects, so that the Mineralogical Museum presented a good collection of the whole spectrum of the field. The pugnacious nature of Weiss resulted in many points of friction. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20010040102" target="_blank">10.1002/mmng.20010040102</a>

Abstract:

This issue of Mineralogical Magazine is the 5th in a loosely defined series of special thematic issues (or part issues), deriving from conferences organized by the Mineralogical Society. The associated conference was entitled ‘Environmental Mineralogy, Geochemistry and Human Health’ and took place in January 2005, in Bath. A common thread to all these Mineralogical Society conferences has been the role of mineralogy in applied science and technology and particularly in environmental science, focussing on the multidisciplinarity of modern mineralogy; the conferences (and special issues) have been particularly successful in bringing along scientists from outside traditional Mineralogy/Earth Sciences. Notably, the series comes at a time when the popularity of Mineralogy/Geology, but also science in general, is low, and many, particularly young, scientists are seeking to place themselves in a better position in the eye of the public and the media, and often also to find new focus for their research. A primary ambition for the series is thus to demonstrate Mineralogy's extensive outreach and has so far succeeded in giving the scientific community a sense of the wider role mineralogists can play.

Abstract:

Effective energy-dispersive X-ray spectroscopy analysis (EDX) with a scanning electron microscope of fine-grained materials (submicrometer scale) is hampered by the interaction volume of the primary electron beam, whose diameter usually is larger than the size of the grains to be analyzed. Therefore, mixed signals of the chemistry of individual grains are expected, and EDX is commonly not applied to such fine-grained material. However, by applying a low primary beam acceleration voltage, combined with a large aperture, and a dedicated mineral classification in the mineral library employed by the Zeiss Mineralogic software platform, mixed signals could be deconvoluted down to a size of 200 nm. In this way, EDX and automated quantitative mineralogy can be applied to investigations of submicrometer-sized grains. It is shown here that reliable quantitative mineralogy and grain size distribution assessment can be made based on an example of fault gouge with a heterogenous mineralogy collected from Ikkattup nunaa Island, southern West Greenland.

Abstract:

Near-Infrared spectroscopy (NIR) is a useful tool for direct and on-site identification of rock mineralogy in spite of the difficulties arising in spectral evaluation, due to limited availability of spectral libraries at the time. Especially in the field, a functional methodology for the identification and evaluation if possible, of the geologic materials, is of interest to many researchers. However, several different parameters (such as grain size, color, mineralogy, texture, water content etc.) can affect the spectroscopic properties of the samples resulting in spectral variability. The subject of the present work focuses in various lithotypes (monzodiorite, diorite, altered diorite, actinolite schist, cataclasite, slate) from Kos Island, Aegean Sea, in Greece, all bearing hydrous minerals in various amounts. The evaluation of the results obtained from NIR spectroscopy offered important qualitative information about the mineralogy of the lithotypes examined. The important asset of the method is that no sample preparation was necessary. From the reflectance spectra, the NIR-active minerals that were identified include chlorite, micas, amphiboles and epidotes. Petrographic and mineralogic analyses were also employed in order to confirm the NIR results and provide more detailed information about the mineralogy of the samples, the grain size and the orientation of the minerals. Correlation of wavelength positions at ~1400 nm with loss on ignition (LOI) values led us to relate the various lithotypes in terms of their petrological affinities. NIR spectroscopy was proved to be a useful tool, especially for the mineralogic identification of rocks underwent low- to medium grade metamorphism, from greenschist to amphibolite facies.

Abstract:

Clay minerals are the most reactive and important inorganic components in soils, but soil mineralogy classifies as a minor topic in soil sciences. Revisiting soil mineralogy has been gradually required. Clay minerals in soils are more complex and less well crystallized than those in sedimentary rocks, and thus, they display more complicated X-ray diffraction (XRD) patterns. Traditional characterization methods such as XRD are usually expensive and time-consuming, and they are therefore inappropriate for large datasets, whereas visible and near-infrared reflectance spectroscopy (VNIR) is a quick, cost-efficient, and nondestructive technique for analyzing soil mineralogic properties of large datasets. The main objectives of this review are to bring readers up to date with information and understanding of VNIR as it relates to soil mineralogy and attracts more attention from a wide variety of readers to revisit soil mineralogy. We begin our review with a description of fundamentals of VNIR. We then review common methods to process soil VNIR spectra and summary spectral features of soil minerals with particular attention to those <2 μm fractions. We further critically review applications of chemometric methods and related model building in spectroscopic soil mineral studies. We then compare spectral measurement with multivariate calibration methods, and we suggest that they both produce excellent results depending on the situation. Finally, we suggest a few avenues of future research, including the development of theoretical calibrations of VNIR more suitable for various soil samples worldwide, better elucidation of clay mineral-soil organic carbon (SOC) interactions, and building the concept of integrated soil mapping through combined information (e.g., mineral composition, soil organic matter-SOM, SOC, pH, and moisture).

Abstract:

Abstract Mineralogy is a fundamental characteristic of a given rock mass throughout the mining value chain. Understanding bulk mineralogy is critical when making predictions on processing performance. However, current methods for estimating complex bulk mineralogy are typically slow and expensive. Whole-rock geochemical data can be utilized to estimate bulk mineralogy using a combination of ternary diagrams and bivariate plots to classify alteration assemblages (alteration mapping), a qualitative approach, or through calculated mineralogy, a predictive quantitative approach. Both these techniques were tested using a data set of multielement geochemistry and mineralogy measured by semiquantitative X-ray diffraction data from the Productora Cu-Au-Mo deposit, Chile. Using geochemistry, samples from Productora were classified into populations based on their dominant alteration assemblage, including quartz-rich, Fe oxide, sodic, potassic, muscovite (sericite)- and clay-alteration, and least altered populations. Samples were also classified by their dominant sulfide mineralogy. Results indicate that alteration mapping through a range of graphical plots provides a rapid and simple appraisal of dominant mineral assemblage, which closely matches the measured mineralogy. In this study, calculated mineralogy using linear programming was also used to generate robust quantitative estimates for major mineral phases, including quartz and total feldspars as well as pyrite, iron oxides, chalcopyrite, and molybdenite, which matched the measured mineralogy data extremely well (R2 values greater than 0.78, low to moderate root mean square error). The results demonstrate that calculated mineralogy can be applied in the mining environment to significantly increase bulk mineralogy data and quantitatively map mineralogical variability. This was useful even though several minerals were challenging to model due to compositional similarities and clays and carbonates could not be predicted accurately.

Abstract:

It is shown that the origins of technological mineralogy in Russia are associated with the name of Academician V. M. Severgin, who at the end of the 18th century introduced the concept of «technological and economic» mineralogy. The stage of development of 1921—1955 is considered as important for the formation of the school of applied mineralogy. The next stage is the implementation of the principles of technological mineralogy in the practice of geological exploration and mining production and the creation of the Technological Mineralogy Commission of the All-Union Mineralogical Society by the beginning of 1983. The main directions of the development of technological mineralogy and the role of the published works of the commission are substantiated.

Abstract:

Periodic Scientific Readings named after Academician Yevhen Lazarenko were offered by his students and followers from the Department of Mineralogy of Ivan Franko National University of Lviv and Ukrainian Mineralogical Society. The corresponding decision was made by the participants of the scientific conference (1997) dedicated to the 80th anniversary of Ye. Lazarenko. After all, perpetuating the memory of outstanding scientists and assessing the importance of their contribution to the development of basic science is impossible without scientific forums organized in their honour. Eleven such Scientific Readings have already taken place, in which scientists, teachers, geologists-practitioners, graduate students and students of Ukraine and other countries took part. Participants of the Readings discussed various problems of mineralogy and related sciences (crystallography, geochemistry, petrography, the study of mineral deposits, etc.) and identified the role of Ye. Lazarenko and his Scientific Mineralogical School in the development of mineralogy in Ukraine and abroad, because, being patriot of Ukraine, Yevhen Kostiantynovych believed that science has no borders. Almost all Readings were thematic, dealing with the problems of regional and genetic mineralogy, mineralogical crystallography, applied mineralogy, history of science, as well as various aspects of space mineralogy, mineral ontogeny, thermobarogeochemistry, biomineralogy, technological and ecological mineralogy. Their materials have been published in separate editions and in the “Mineralogical Collection”, founded by Ye. Lazarenko. The results of the research presented during the Academician Yevhen Lazarenko Scientific Readings and published in different editions are extremely diverse and important both from a theoretical and applied point of view. Undoubtedly, they significantly enriched the mineralogical science not only in Ukraine but also in general, and testified to the fundamental nature of the scientific heritage of the outstanding scientist of the twentieth century – Academician Yevhen Lazarenko. Key words: Academician Yevhen Lazarenko, Scientific Readings, mineralogy, scientific directions of modern mineralogy, history of science, Ivan Franko National University of Lviv.

Abstract:

The ability to apply automated quantitative mineralogy (AQM) on metamorphic rocks was investigated on samples from the Fiskenæsset complex, Greenland. AQM provides the possibility to visualize and quantify microstructures, minerals, as well as the morphology and chemistry of the investigated samples. Here, we applied the ZEISS Mineralogic software platform as an AQM tool, which has integrated matrix corrections and full quantification of energy dispersive spectrometry data, and therefore is able to give detailed chemical information on each pixel in the AQM mineral maps. This has been applied to create mineral maps, element concentration maps, element ratio maps, mineral association maps, as well as to morphochemically classify individual minerals for their grain shape, size, and orientation. The visualization of metamorphic textures, while at the same time quantifying their textures, is the great strength of AQM and is an ideal tool to lift microscopy from the qualitative to the quantitative level.

Abstract:

This work presents a novel algorithm that achieves enhanced resolution of well logging signals, e.g., from 1 ft of a pulsed neutron mineralogy tool to 0.04 ft of an imaging tool. The algorithm, denoted as “Digital Core,” combines mineralogical and sedimentological information to generate a high-resolution record of the formation mineralogy which can be consequently applied to thin bedded environments. The keystone to the philosophy of this algorithm is that the spectral information recorded by mineralogy tool is a weighted average of the mineralogy of each lithological component in the analyzed volume. Therefore, by using a high-resolution image log to determine the proportion of each lithological component, their composition can be determined from the mineralogy log data. A field case from a well located in South Australia is presented in this work, and the results validate the feasibility of an integrated core-level petrophysical analysis in a cost-effective and timely manner compared to conventional core measurements.

Abstract:

AbstractCurrent advances and developments in automated mineralogy have made it a crucial key technology in the field of process mineralogy, allowing better understanding and connection between mineralogy and the beneficiation process. The latest developments in X‑ray micro-computed tomography (µCT) have shown a great potential to let it become the next-generation automated mineralogy technique. µCT’s main benefit lies in its capability to allow 3D monitoring of the internal structure of the ore sample at resolutions down to a few hundred nanometers, thus excluding the common stereological error in conventional 2D analysis. Driven by the technological and computational progress, µCT is constantly developing as an analysis tool and successively it will become an essential technique in the field of process mineralogy. This study aims to assess the potential application of µCT systems, for 3D ore characterization through relevant case studies. The opportunities and platforms that µCT 3D ore characterization provides for process design and simulation in mineral processing are presented.

Abstract:

Spatially associated red (Typic Hapludalf) and black (Vertic Eutropept) soils developed on the Deccan plateau in the Western Ghats of India were analysed for clay mineralogy and also physical properties relating to shrink–swell. This was done in order to examine a possible correlation between shrink–swell phenomena and the content of expansible clay minerals, and to reconcile the apparent incompatibility between such a correlation and the classification of some Vertisols into kaolinitic, illitic, and mixed mineralogy classes. The fine clay mineralogy of the red soil was dominated by interstratified smectite/kaolinite with a little amount of smectite, but it had low cation exchange capacities and other associated non-vertic physical properties. Some of the smectite was interlayered with chlorite. This red soil is grouped into the kaolinitic mineralogy class. The fine clay mineralogy of the black soil was dominated by a highly smectitic interstratified smectite/kaolinite and also some smectite, which also shows some interlayering with chlorite. This soil has vertic physical properties but has a mixed mineralogy classification. The results suggest that there is an incompatibility between marked shrink–swell characteristics and mineralogical classification of soils in Soil Taxonomy, in view of the fact that it is smectite content which governs the vertic character of soils.

Abstract:

Information on the history of mineralogical research and knowledge in the independent Ukraine (since 1991) іs summarized in the book. The world-famous scientific schools formed in the second half of the 20th century (1940–1990): regional mineralogical, thermobarogeochemical, crystallochemical, mineral physics are characterized. The achievements of scientists in regional, systematic and genetic mineralogy, crystal chemistry and mineral physics, mineralogical crystallography, bio- and nano-mineralogy, experimental, space and applied mineralogy, museum work, etc. were analyzed. It is shown that after the crisis of the 1990s, traditional scientific directions are expanding and deepening, and new scientific directions are being initiated, in particular nanomineralogy and ecological mineralogy, the number of minerals discovered in the depths of Ukraine is growing rapidly, new periodical editions, textbooks and manuals are appearing, work is underway to create of the modern monographic summary – the Ukrainian mineralogical encyclopedia. The analysis of the obtained mineralogical and historical knowledge aims at new achievements in the field of mineralogy within the framework of the next major research path – «to develop all scientific directions of mineralogy, but with an emphasis on giving priority to regional mineralogical and applied works». The publication shows the ways of development and the fate of mineralogy in crisis conditions, especially at the modern stage in the complex geopolitical conditions of today, in particular during the war with an external aggressor, therefore, it is timely and necessary, both for specialists in the field of Earth sciences, first of all, for geologists and mineralogists – scientists, teachers, practitioners, and for those who are interested in the history of science.

Abstract:

Weathering of soil minerals provides base cations that buffer against acidity, and nutrients that support plant growth. In general, direct observations of soil minerals are rare; however, their abundance can be determined indirectly through soil geochemistry using normative-calculation procedures. This study compiled a data set of major oxide content from published and archived soil geochemical observations for 1170 sites across Canada (averaged over the soil profile [A, B, and C horizons], weighted by depth and bulk density to a maximum depth of 50 cm). Quantitative soil mineralogy (wt%) was systematically determined at each site using the normative method, ‘Analysis to Mineralogy’ (A2M); the efficacy of the approach was evaluated by comparison to X-ray Diffraction (XRD) mineralogy available for a subset of the study sites. At these sites, predicted A2M mineralogy was significantly related to estimated XRD, showing a strong linear relationship for plagioclase, quartz, and K-feldspar, and a moderate linear relationship for chlorite and muscovite. Further, the predicted A2M plagioclase content was almost identical to the estimated XRD soil mineralogy, showing no statistical difference. The Canada-wide predicted quantitative soil mineralogy was consistent with the underlying bedrock geology, such as in north-western Saskatchewan and north-eastern Alberta, which had high amounts of quartz due to the Western Canadian Sedimentary Basin. Other soil minerals (plagioclase, potassium feldspar, chlorite, and muscovite) varied greatly in response to changing bedrock geology across Canada. Normative approaches, such as A2M, provide a reliable approach for national-scale determination of quantitative soil mineralogy, which is essential for the assessment of soil weathering rates.

Abstract:

Using a variety of recent public-domain data sets comprising porosity, velocity (P- and S-waves), and, in most cases, mineralogy and petrographic data, I created an extensive global data set and evaluated the importance of mineralogy and pore type on the elastic properties behavior of carbonate core plugs. Results from this investigation clearly illuminated the potential for overinterpreting elastic properties behavior as a function of pore type(s) when mineralogy was not explicitly included in the analysis. Rock-physics analysis using a combination of heuristic and theoretical models illustrated that mineralogy exerted a significant additional variation on velocity at a given porosity. Failure to account for mineralogy exacerbated inferences about the effect of pore type(s) made using a comparison of P-wave velocity to an inappropriate empirical model (Wyllie) that did not account for pore shape(s). In this analysis, extreme variability in carbonate velocity was observed in only portions of two data sets, when mineralogy was explicitly considered and robust models that accounted for inclusion (pore) shape were used. Results from this analysis resulted in a recommended workflow, including a rock-physics template and dry-rock modulus diagnostics, for the evaluation of lab-based carbonate rock-physics data. The workflow was amenable to further integration with well-based data and other core-based petrophysical measurements (e.g., electrical properties).

Abstract:

Abstract. Impurities in polar ice do not only allow the reconstruction of past atmospheric aerosol concentrations but also influence the physical properties of the ice. However, the localisation of impurities inside the microstructure is still under debate and little is known about the mineralogy of solid inclusions. In particular, the general mineralogical diversity throughout an ice core and the specific distribution inside the microstructure is poorly investigated; the impact of the mineralogy on the localisation of inclusions and other processes is thus hardly known. We use dust particle concentration, optical microscopy, and cryo-Raman spectroscopy to systematically locate and analyse the mineralogy of micro-inclusions in situ inside 11 solid ice samples from the upper 1340 m of the East Greenland Ice Core Project ice core. Micro-inclusions are more variable in mineralogy than previously observed and are mainly composed of mineral dust (quartz, mica, and feldspar) and sulfates (mainly gypsum). Inclusions of the same composition tend to cluster, but clustering frequency and mineralogy changes with depth. A variety of sulfates dominate the upper 900 m, while gypsum is the only sulfate in deeper samples, which however contain more mineral dust, nitrates, and dolomite. The analysed part of the core can thus be divided into two depth regimes of different mineralogy, and to a lesser degree of spatial distribution, which could originate from different chemical reactions in the ice or large-scale changes in ice cover in northeast Greenland during the mid-Holocene. The complexity of impurity mineralogy on the metre scale and centimetre scale in polar ice is still underestimated, and new methodological approaches are necessary to establish a comprehensive understanding of the role of impurities. Our results show that applying new methods to the mineralogy in ice cores and recognising its complexity, as well as the importance for localisation studies, open new avenues for understanding the role of impurities in ice cores.
