Book excerpt: The Saxo-Thuringian Zone is pivotal for understanding the Variscan evolution of Central Europe, as this part of Gondwana was one of the first to collide with Laurussia. The Saxo-Thuringian Zone comprises domains that have experienced variable degrees of Variscan metamorphism ranging from medium grade to UHT/UHP in some domains, while other parts were largely unaffected by deformation or metamorphism. These differences in overprint reflect pre-Variscan crustal heterogeneity and thickness variation, where thinner segments were wedged into the subduction zone and rigid, thicker blocks escaped subduction. The heterogeneity of crustal thickness is considered to be caused by Ordovician rifting (470480 Ma) of the Cadomian crust (570540 Ma) at the Gondwana margin. Today, magmatic and sedimentary rocks deposited on the thin crust of these rifts form the metamorphic complexes of the Saxon Granulite Massif and the Erzgebirge Mtns. Variable response of crust of different thickness to Variscan deformation and metamorphism is not particular to the Saxo-Thuringian Zone, but rather a typical feature of the crust all over Variscan Europe. The 18 chapters of this book are review and synthesis papers and present overviews of the Cadomian evolution, the post-Cadomian development of the passive margin, a state of the art assessment of the biostratigraphic record of Saxo-Thuringian sediments, various aspects (metamorphism, structure, magmatism) of the Variscan reworking of the Saxo-Thuringian Zone and processes related to the erosion of the Variscan Orogen. Extensive references include also older, generally difficult to find literature references, PhD theses and original descriptions published in very local journals. This book makes use of, and in part provides, previously unavailable maps and borehole data, largely acquired in GDR time in the course of exploration for uranium, fossil fuels, and ore minerals. The geological sheet map of the Pre-Permian geology of Eastern Germany, based on this material and compiled by SDAG Wismut (now WISMUT GmbH), is included and made available for the first time to a wider audience. Numerous figures and additional materials are provided on the enclosed DVD.

Available in PDF, EPUB and Kindle. Book excerpt: The Alps are an arched mountain chain stretching 1500 km between Vienna and Graz in Austria and Genova in Italy. They resulted from the collision of the African and Laurasian plates during Mesozoic and Tertiary times. The high standard of knowledge attained over the last 30 years by the working groups on "Alpine Metamorphism" is well known and helped considerably to recognize pre-Mesozoic elements in the Alps. In Part I of this book the subdivision of the major Alpine units and pre-Mesozoic pal inspastic reconstructions are covered before discussion of the pre-Mesozoic geology in Parts II, III and IV It is understood that the Mesozoic and later events overprinted pre-existing structures veiling the earlier history and the nature of protoliths. Although the Alpine overprint does not facilitate the recognition of older struc tures, pre-Mesozoic basement units were recognized during the first beginnings of geological observations in the Alps, about 200 years ago. Fifty percent of the Alpine domain is underlain by basement units that have been unconformably covered since Permian and Mesozoic times. This basement appears today in a complex pattern among the Alpine structures. The history of their discovery and explanation, parallel with a growing sophistication of research methods, are the subject of the introductory chapter of Part II.

This book was released on 2023-06-07 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.

Book excerpt: This richly illustrated book presents Germany’s geological evolution in the context of the Earth’s dynamic history. It starts with an introduction to Geology and explains the plate tectonic development, as well as the formation of both ancient and recent mountain belts – namely the Caledonian, Variscan and the modern-day Alps – that formed this part of Europe. A dedicated chapter discusses the origin of earthquakes in Germany, the occurrence of young volcanic rocks and the various episodes of rock deformation and metamorphism at these complex crossroads of plate tectonic history. The book highlights Germany’s diverse geological history, ranging from the origin of the Earth, the formation of deep crystalline rocks, and their overlying sedimentary sequences, to its more recent “ice age” quaternary cover. The last chapter addresses the shaping of the modern landscape. Though the content is also accessible for non-geologists, it is primarily intended for geoscience students and an academic audience.

Available in PDF, EPUB and Kindle. Book excerpt: Special Publication 503 celebrates the career of R. Damian Nance. It features 27 articles, with more than 110 authors based in 18 different countries. These articles include contributions on the processes responsible for the formation and breakup of supercontinents, the controversies concerning the status of Pannotia as a supercontinent, the generation and destruction of Paleozoic oceans, and the development of the Appalachian-Ouachitan-Caledonide-Variscan orogens. In addition to field work, the approaches to gain that understanding include examining the relationships between stratigraphy and structural geology, precise geochronology, geochemical and isotopic fingerprinting, geodynamic modelling, regional syntheses, palaeogeographic modelling, and good old-fashioned arm-waving! The wide range of topics mirrors the breadth and depth of Damian’s contributions, interests and expertise. Like Damian’s papers, the contributions range from the predominantly conceptual to detailed field work, but all are targeted at understanding important tectonic processes. Their scope not only varies in scale from global to regional to local, but also in the range of approaches required to gain that understanding.

Available in PDF, EPUB and Kindle. Book excerpt: This volume summarizes the state of the art of Variscan geology from Iberia to the Bohemian Massif. The European Variscan belt consists of two orogens: the older, northern and the younger, southern. The northern Variscan realm was dominated by Late Devonian–Carboniferous rifting, subduction and collisional events as defined by sedimentary records, crustal growth, recycling of continental crust and large-scale deformations. In contrast, the southern European crust was reworked by major Late Carboniferous collision followed by Permian wrenching. The Late Carboniferous–Permian orogeny overprinted the previously accreted system in the north, but with much lower intensity, resulting in magmatic recycling and extensional tectonics. These two main orogenic cycles do not reflect episodic evolution of a single orogenic system but a complete change in orientation of stress field, thermal regime, degree of reworking and recycling of European crust, reflecting a major switch in plate configurations at the Early–Late Carboniferous boundary.

This book was released on 2016-10-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

Available in PDF, EPUB and Kindle. Book excerpt: Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over the last 600 Ma of Earth's history. The geological record starts with the amalgamation of Gondwana in the Neoproterozoic succeeded by the rifting and spreading of the Rheic ocean; its demise, which led to the amalgamation of Pangea in the late Paleozoic; the rifting and spreading of several arms of the Neotethys ocean in the Mesozoic Era and their ongoing closure, which was responsible for the Alpine orogeny. The significant advances in the last 20 years have attracted international research interest in the geology of the Iberian Peninsula. This volume presents the most comprehensive, careful and updated description of the variscan cycle in Iberia. This volume focuses in the different geological events since the Cambrian-Early Ordovician rift until the late variscan orocline formations including magmatic and metamorphic evolution.

This book was released on 2015-10-15 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will broaden readers’ understanding of pegmatites in a special geodynamic setting, dealing with the emplacement of the Hagendorf-Pleystein Pegmatite Province (HPPP) in the Central European Variscides. This treatise illustrates the complex processes leading to the formation and partial destruction of the pegmatites, documenting the geochronological, chemical, mineralogical, geological and geomorphological / sedimentological data set. The book starts with a detailed account of the economic geology of the various pegmatites, explaining why these deposits are a major resource of ceramic raw materials. In its concluding section, a model of the pegmatite evolution in an ensialic orogen provides meaningful insights into the genetic aspects of pegmatite generation. The Late Paleozoic rare-element pegmatites of the HPPP, Oberpfalz-SE, Germany, rank among the largest concentrations in Europe. The biggest pegmatite of this mining district totals 4.4 million tons of ore (Hagendorf-South). The mining history of the HPPP is restricted to the 20th century, when local entrepreneurs started mining operations in search of ceramic raw materials, feldspar and quartz. Today the “Silbergrube Aplite” is still worked for feldspar. The traditional mining of pegmatitic and aplitic rocks in Central Europe, such as the Bohemian Massif, which is shared by Germany, the Czech Republic, Poland and Austria, has been focused on these industrial minerals. In addition to these major commodities, lithium was mined for a period of time. But even today many of these pegmatites of calc-alkaline affiliation have not lost their appeal to mineralogists and mineral enthusiasts for their wealth of minerals that contain P, Nb, Ta, Li, Be, B, U, Th, Sc, Ti and Sn. The most favorable crustal section to bring about pegmatitic rocks of this type, encompassing pegmatoids, metapegmatites, reactivated pseudopegmatites and pegmatites sensu stricto is the ensialic orogen, exemplified by the Variscan (Hercynian) Orogen, which geodynamically connects the Paleozoic pegmatite provinces in North America and Europe. The geological history of the HPPP, however, goes much further than the Carboniferous-Permian magmatic activity, when the last structural disturbances of the Variscan orogeny affected the NE-Bavarian Basement between 450 and 330 Ma. During this time mafic magmatic rocks together with calcareous and arenaceous sediments were converted into paragneisses, calcsilicate rocks, and amphibolites. It is the period of time when tectonic shortening led to over thrusting and when the emplacement of nappes and the architectural elements of the ensialic orogen began taking shape. During the Late Permian, the Mesozoic and the Cenozoic, the HPPP did not lie idle in geological terms; hypogene and supergene alteration continued and found its most recent expression in alluvial-fluvial “nigrine” placer deposits, which resulted from the unroofing of the pegmatites and aplites in the HPPP and can be used even outside HPPP as an ore guide to pegmatites.

Available in PDF, EPUB and Kindle. Book excerpt: Ancient ice ages are revealed by distinctive stratal facies that tell us much about the times of coolness and how the climate system works. Several strong ice ages were recorded in the late Paleozic time and during transitions from the Devonian in to the Carboniferous and from the Ordovician in to the Silurian. In Precambrian time, several are documented for both the late and early Proterozoic age. This title explores findings on the pre-Mesozoic ice ages, examining climate in relation to tectonobiogeochemical activities rooted in the changing earth-air-ocean system.
