Four isolated occurrences of Tertiary volcanic rocks in the northern Spessart at Beilstein, Hoher Berg, Madstein and Kasselgrund are relics of volcanic vents or dikes. They display alkaline basalts (s. l.) with mainly trachybasaltic composition, which, from normative mineral contents, may be designated as nepheline-bearing alkali-olivine basalts and basanites. In part, centimetre-sized xenoliths of spinel lherzolite occur. According to Ar-Ar dating, the alkaline basalts (s. l.) from Kasselgrund have erupted at 18.1 ± 0.3 or 19.3 ± 0.4 Ma, those of Hoher Berg between c. 18 and c. 21 Ma. These ages correspond to the Vogelsberg eruption stage I. A slightly younger Ar-Ar age of 16.8 ± 0.3 Ma was recorded for the Beilstein basalt, which is in chronological accordance to the turn of Vogelsberg eruption stages II and III. Samples of all four occurrences reveal major and trace element compositions, which are different from those of the Vogelsberg basalts. Compositions of basalts of the stage III from Vogelsberg coincide most with the Spessart basalts. This signals a special position of the northern Spessart volcanic rocks either as a discrete spatial part of the Vogelsberg volcanic suite or as smaller, independent eruption centres.

Abstract. This field trip is intended to present an introduction to the geological and geomorphological evolution of Giessen and its surrounding areas (Fig. 1). The conference location of Giessen is located at the intersection of three major geological and morphological units: the Rheinisches Schiefergebirge (Rhenish Massif) to the west, the Hessische Senke (Hessian Depression) to the north and south and the Vogelsberg volcanic field to the east (Fig. 2). The rocks of the Rheinisches Schiefergebirge (Rhenish Massif) were formed during Paleozoic times, in the context of the Variscan orogeny. Dominant rock types include graywacke, slate, quartzite, and limestone, as well as mafic and felsic volcanics and their related pyroclastics. The area north and south of Giessen is dominated by the Hessische Senke (Hessian Depression), a north–south-trending subsidence area with several individual deposit segments. Due to Cenozoic tectonic activity, the Hessian Depression can be regarded as a connecting segment between the prominent Upper Rhine Graben and the smaller graben structures of northern Germany, and this is also documented by less consolidated Tertiary and Quaternary sediments. Long-lasting subsidence of the Hessian Depression, however, is indicated by the presence of Permian and Mesozoic sedimentary rocks. Rotliegend rocks are present towards the southwest rim of the Vogelsberg volcanic field and the Hanau-Seligenstädter Senke. Minor occurrences of Zechstein rocks are exposed along the Lahn valley between Giessen and Marburg. Mesozoic strata are dominated by Buntsandstein and are widespread in the Marburg area, with Muschelkalk and Keuper rocks being restricted to small erosional remnants in tectonic graben structures. The area to the east of Giessen is dominated by the Miocene Vogelsberg volcanic field, where an estimated area of 2500 km2 is covered by volcanic rocks of varying thickness, the Vogelsberg thus being the largest volcanic field of central Europe. The field trip provides an introduction to the geology, earth history and geomorphological characteristics of Giessen and its surrounding areas. We will therefore encounter rocks that formed in distinct geodynamic environments and within a timespan of roughly 400 Ma (Devonian to present).

Dem Raum so sagt Simmel, hafte wenig Verhaltensbestimmen des an. Gerade deshalb zeigesich in der räumlichen Bestimmtheit die Art der Vergesellschaftung besonders deutlich. Dies ist ein Programm für ein theoriegeleitetes Verständnis räumlicher Entwicklungen undräumlich indizierter Vergesellschaftung. Diese Arbeit will für eine Theorie des Raumes Anstöße geben und nimmt dabei bewußt in Kauf, eher Vermutungen und Thesen zu formulieren, als über gesichertes Wissen zu berichten. Der Plan für ein derartiges Vorhaben begründet sich auf individuell erfahrener Praxis. Vor nunmehr fünf Jahren kam ich, aus meiner Sicht zufällig, in eine der eher kargen deutschen Mittelgebirgslandschaften, den Vogelsberg, um mit Studenten an einem Entwicklungsplan für eine der dort gelegenen kleineren Städte zu arbeiten. Eines Abends saßen wir, die Studenten, einige Gewerkschaftler, andere Bürger der Stadt und ich, bei einem Bier zusammen, da sagte einer der Einheimischen: Irgendwann werden sie einen Zaun um den Vogelsberg ziehen und uns alle begaffen, wie die Affen im Zoo. Ohne die Bedeutung dieser Aussage richtig einschätzen zu können - wir werden noch sehen, daß sie eine beinahe notwendige psychische Reaktion auf die Modernisierung darstellt - hat mich die hier zum Ausdruck kommende zynische Hoffnungslosigkeit beeindruckt.

Editor's note: At conferences with a focus on scientific and political information about alternative agriculture, the live stories of how individual farmers “made the switch” from chemical intensive to low-chemical farming help us to stay in touch with the issues as the farmer sees them. At the IAA symposium, Kansas farmer John Vogelsberg told the story of his choice to make that transition, delighting the audience with his dry humor, warmth, and wisdom. Following are excerpts from his reflections.

Abstract. The conception that the substratum of the "Lockerbraunerde" of the Hohe Vogelsberg Mountains should represent a Late-Pleistocene, periglacial aeolian sediment, is rejected. It is demonstrated primary by means of radio carbon-datings of fossil Ah-horizons that a large portion of this substratum consists of anthropogenic colluvium. Its development occured most likely already during the earlier Holocene. The findings that the "Deckschutt" and also the substratum of the "Lockerbraunerde" are representing contemporaneous developments of the Younger Dryas are substantiated,

Streszczenie:

A significant amount of information on sedimentary provenance is encoded in the heavy minerals of a sediment or sedimentary rock. This information is commonly assessed by optically determining the heavy-mineral assemblage, potentially followed by geochemical and/or geochronological analysis of specific heavy minerals. The proposed method of semi-automated heavy-mineral analysis by Raman spectroscopy (Raman-HMA) aims to combine the objective mineral identification capabilities of Raman spectroscopy with high-resolution geochemical techniques applied to single grains. The Raman-HMA method is an efficient and precise tool that significantly improves the comparability of heavy-mineral data with respect to both overall assemblages and individual compositions within solid solution series. Furthermore, the efficiency of subsequent analysis is increased due to identification and spatial referencing of the heavy minerals in the sample slide. The method is tested on modern sediments of the Fulda river (central Germany) draining two Miocene volcanic sources (Vogelsberg, Rhön) resting on top of Lower Triassic siliciclastic sediments. The downstream evolution of the volcanic detritus is documented and the capability to analyze silt-sized grains has revealed an additional eolian source. This capability also poses the possibility of systematically assessing the heavy-mineral assemblages of shales, which are often disregarded in sedimentary provenance studies.

AbstractUnshaped basalt blocks from archaeological sites along the border of the Roman Empire (limes) in the lower Rhine area near Vleuten-De Meern (Utrecht) have been studied petrographically, analysed by XRF for major and trace elements, and dated by the 40Ar/39Ar method. The blocks are from a revetment in the bank of a fossil branch of the Rhine and a contiguous ship De Meern 4, both built around 100 AD. All nineteen blocks are alkali olivine basalt (AOB) with xenoliths of peridotite derived from the upper mantle and quartz xenocrysts from the continental crust; eighteen blocks contain resorbed plagioclase xenocrysts as well. Abundances of major and trace elements show that those eighteen samples form a chemically coherent group. The outlier, different in chemistry and without plagioclase xenocrysts, is from the ship. A basalt block from ship De Meern 1 (148 AD) conforms compositionally to the defined group. AOB lumps from a limes watchtower (2nd-3rd century) form a chemically distinct group.Low SiO2 contents (<46 wt.%) and high abundances of Mg, Ti, Ni, and Sr indicate a within-plate origin, directly from primitive melts; proportions of selected trace elements point at a continental rift setting. In the archaeological context, the most likely source region for the blocks is the Cenozoic European Volcanic Province, upstream along the Rhine and its tributaries.The petrographic and analytical data of the blocks have been compared with 432 published analyses of German AOB. On petrographic grounds, the Eifel can be ruled out as a source area since typical Eifel basalt minerals, amphibole, biotite, K-feldspar and feldspatoids, are absent in the blocks. Applying seven geochemical criteria, based on abundances of major elements in the Roman blocks, twelve sites with matching AOB were found in the Siebengebirge, seven in the Vogelsberg, and one in the Westerwald.The ages of the blocks (26.3 - 28.5 Ma) are compatible with ages determined for AOB from the Siebengebirge (27.4 - 29.9 Ma), and preclude their provenance from the Vogelsberg (< 18 Ma). The matching Westerwald sample is from 60 km beyond the limes, a prohibitive distance from the perspective of Roman logistics.AOB quarries of optimal logistic position are located adjacent to the Rhine, between Bonn and Remagen, a zone with significant Roman settlements from the first century AD. Geochemical correlation indicates AOB bodies at Rolandsbogen and Godesburg (S of Bonn) as potential sources of the blocks from the 100 AD revetment and ships. Similarly, the Erpeler Ley (E of Remagen) is indicated as the likely source for the blocks from a 2nd-3rd century AD watchtower.As the Godesburg basalt is at 1.6 km from the Rhine today, it is not obvious how the blocks were transported from there. However, it may be that the adjacent, now sanded, branch of the old Rhine river system, was navigable for flat-bottomed vessels in Roman times.Our study demonstrates that substantial detailed information regarding ancient mining and trading activities can be retrieved from seemingly indistinctive basalt blocks.

Streszczenie:

Rückläufige Bestandsentwicklungen und fortschreitende Arealverluste wurden bei der Flußperlmuschel in Mitteleuropa bereits um 1800 konstatiert. — Nach Jahrhunderten intensiver Erforschung dieser Art trat das Interesse an ihr aus kulturhistorischen Gründen in den Hintergrund. Verarmung des Adels und Auflassung der Perlfischerei gepaart mit dem In-Vergessenheit-Geraten des Perlfischerei-Regals sind als die wesentlichsten Gründe zu erwähnen. Auch das biologische Interesse ließ nach den bedeutenden Beiträgen von W. Harms zur Najadenbiologie zu Beginn dieses Jahrhunderts nach. Dabei ist jedoch kritisch anzumerken, daß die Ergebnisse zur Najadenbiologie an den Arten mit großen Glochidien (Larven) gewonnen wurden und die Arten mit sehr kleinen Glochidien wie z. B. die Flußperlmuschel Margaritifera margaritifera (L.) oder die Kleine (Gemeine) Flußmuschel Unio crassus Philipsson nicht untersucht wurden. Hieraus resultierte, daß der Lebenszyklus der Flußperlmuschel noch bis vor ca. 15 Jahren nur bruchstückhaft bekannt war. Für ihre Entwicklung und Biologie wurden ähnliche Verhältnisse angenommen, wie sie an den anderen einheimischen Najadenarten beobachtet wurden. Gegen Ende der sechziger Jahre setzten dann an mehreren Orten kurz nacheinander intensive Untersuchungen an der Flußperlmuschel ein, die durch den sich rapide beschleunigenden Rückgang angeregt wurden (Lüneburger Heide, Vogelsberg und Fichtelgebirge/Bayerischer Wald). — Die Berichte über das Erlöschen von Populationen der Flußperlmuschel mehrten sich seit den siebziger Jahren in Mitteleuropa und rückten die Flußperlmuschel wieder in den Blickwinkel des Interesses von Biologen und Naturschützern. Nicht zuletzt eine verstärkte Öffentlichkeitsarbeit führte zur Bereitstellung der Mittel zur Durchführung einer flächendeckenden Bestandsüberprüfung der Flußperlmuschel in der Bundesrepublik Deutschland (1985-1987). Diese konnte auf den seit 15 Jahren im Rahmen der Molluskenkartierung erfaßten Sammlungs- und Literaturdaten aufbauen. Im vorliegenden Beitrag wird über die Situation der Flußperlmuschel in der ehemaligen Preußischen Rheinprovinz (Nordrhein-Westfalen, Rheinland-Pfalz und Saarland) berichtet. Hier sind die rechtsrheinischen Standorte heute erloschen und linksrheinisch existieren noch 5 Standorte, für die Artenschutz-Projekte angeregt wurden.

AbstractPetrographic observations and in situ U–Pb ages of melilitites, foidites, basanites, phonolites, and trachytes from the southern part of the Central European Volcanic Province (CEVP) and related plutonic inclusions therein reveal two distinct age groups separated by a gap of ~ 20 Myr. A late Cretaceous to early Eocene group (~ 73–47 Ma; Taunus, Lower Main plain, Odenwald and Kraichgau area, Bonndorfer Graben and Freiburger Bucht area, Vosges and Pfälzerwald) is characterized by nephelinites and basanites mostly devoid of melilite and perovskite, and by rare haüynites, and trachytes. In contrast, a late Oligocene to late Miocene group (~ 27–9 Ma; Lorraine, southern Upper Rhine Graben, Urach, Hegau area) is dominated by melilitites, melilite-bearing nephelinites (both carrying perovskite), and phonolites. Both magmatic episodes are related to domal topographic uplift, erosion, and formation of major angular unconformities in the Upper Rhine Graben, suggesting an association with dynamic topography interrupted by phases of subsidence (or abatements of uplift). The investigated rocks in the southern CEVP (south of a line Eifel–Vogelsberg–Rhön–Heldburg), except for the Kaiserstuhl volcanic complex, mostly comprise small and isolated occurrences or monogenetic volcanic fields, whereas the northern CEVP is dominated by large volcanic complexes and dyke swarms, which are mostly SiO2-saturated to weakly SiO2-undersaturated. In the northern CEVP, evidence of spatially varying but recurrent volcanic activity exists since the Eocene, lacking the distinct 20 Myr gap as documented from the southern CEVP. While the temporal and spatial distribution of volcanism are a result of the Cretaceous to Miocene tectonic evolution in Central Europe, further studies are needed to explain the petrographic differences between the two age groups in the south.
