Early–Middle Ordovician nappe tectonics of the junction between the Kokchetav HP-UHP metamorphic belt and the Stepnyak paleoisland arc

The North Kokchetav tectonic zone is located between the Kokchetav HP-UHP metamorphic belt and the Stepnyak zone of Ordovician island arc and oceanic complexes. The Kokchetav zone is a collage of nappes (thrust sheets) that consist of basement gneiss and sedimentary rocks of the Kokchetav microcontinent, granite gneiss, mica schists with eclogite blocks, the Shchuch’e ophiolite, Middle Proterozoic felsic volcanics, and Arenigian siliceous-terrigenous sediments with olistostromes. The latter are of gravity-sliding origin and their clastic material includes quartz-muscovite and quartz-garnet-muscovite schists, gneiss, dolomite, and amphibolite. The sheet boundaries are marked by mylonite and Early Ordovician mica schists (40Ar/39Ar ages of syntectonic muscovite are 489–469 Ma). The North Kokchetav collage of compositionally diverse thrust sheets can be interpreted as a collisional zone. According to geological evidence, tectonic activity in the zone lasted as late as the Middle Ordovician. Syncollisional thrusting in the North Kokchetav zone was coeval with the latest dynamic metamorphic event in the history of the Kokchetav belt. All events of retrograde metamorphism and exhumation of HP and UHP rocks in the belt have Cambrian ages, i.e., the rocks had been exhumed prior to the Early–Middle Ordovician collisions and the related orogeny.

Earth Structure: An Introduction to Structural Geology and Tectonics (Second Edition) / Строение Земли - Введение в структурную геологию и тектонику (второе издание)

This book is concerned with the deformation of rock in the Earth’s lithosphere, as viewed from the atomic scale, through the grain scale, the hand specimen scale, the outcrop scale, the mountain range scale, and the tectonic plate scale. A deformational feature observed on one scale typically reflects processes occurring on other scales. For example, we can’t understand continental deformation without understanding mountains, we can’t understand mountains without understanding folding and faulting, and we can’t understand folding and faulting without understanding ductile and brittle deformation mechanisms at the atomic scale. This book attempts to integrate topics pertaining to all scales of rock deformation, emphasizing the linkages between structural geology and tectonics.

Данная книга рассматривает деформацию пород в литосфере Земли , которая наблюдается на атомном уровне, переходя на масштаб зерна, образца, обнажения, горного хребта и тектонической плиты. Деформационные особенности, наблюдаемые в одном масштабе, закономерно отражают процессы, возникающие в другом масштабе. К примеру, мы не можем понять деформацию континента без понимания процессов горообразования, мы не можем понять горообразование без понимания процессов образования складок и разломов, и мы не можем понять процессы складкообразования и разрывных нарушений без понимания механизмов пластичной и хрупкой деформации на атомарном уровне. Эта книга пытается объединить темы, касающиеся деформации пород на всех уровнях, подчеркивая связь между структурной геологией и тектоникой.

Eclogites of the Late Cambrian–Early Ordovician North Kokchetav tectonic zone (northern Kazakhstan): structural position and petrology

We consider the structural position and petrology of eclogites in the North Kokchetav accretion-collision zone located north of the Kokchetav metamorphic belt formed by high- and ultrahigh-pressure rocks. In the Early Ordovician North Kokchetav tectonic zone, thin sheets of mylonite and diaphthoric gneisses with eclogites are tectonically conjugate with the volcanic and sedimentary rocks of the Stepnyak paleoisland-arc zone. Eclogites have been revealed at two sites of the North Kokchetav tectonic zone—Chaikino and Borovoe. The Chaikino eclogites formed at 800–850 °C and 18–20 kbar, and the Borovoe eclogites, at 750–800 °C and 17–18 kbar. Study of pyroxene-plagioclase symplectite replacing omphacite of the eclogites at both sites has recognized three stages of regressive magmatism: (1) formation of coarse-grained clinopyroxene-plagioclase symplectite at 760–790 °C and 11–12 kbar, (2) formation of fine-grained clinopyroxene-plagioclase symplectite at 700–730 °C and 7–8 kbar, and (3) amphibolization of pyroxene at 570–600 °C and 5–6 kbar. The Ar-Ar age of muscovite from the Borovoe mica schists hosting eclogites is 493 ± 5 Ma, which corresponds to the time of cooling of metamorphic rocks to <370 °C. Hence, the peak of high-pressure metamorphism and all recognized stages of retrograde changes are dated to the Cambrian. The geological data evidence that eclogite-schist-gneiss sheets were localized in the accretion-collision zone and became conjugate with sedimentary and volcanic rocks no later than in the Middle Ordovician

Einfuhrung in die Erdgeschichte

Die Erdgeschichte ist der eigenartigste Zweig der Geologie, welcher die kausal-naturwissenschaftliche und die historische Betrachtungsweise verknüpft; sie eignet sich daher besonders gut zur Einführung, sofern eben diese spezifische Betrachtungsweise deutlich gekennzeichnet und klar herausgearbeitet wird. Die Schilderung darf also nicht in einer einfachen Materialsammlung steckenbleiben, sondern muß, von den Voraussetzungen ausgehend, über die Sichtung und Ordnung des Materials zu einem Gesamtbild zu gelangen versuchen, welches, über spezialwissenschaftliche Erkenntnis hinaus, den weltanschaulichen Gehalt der Erdwissenschaft zu kennzeichnen vermag. Wenn auch das Endziel heute noch fern erscheint, so ist doch der Weg klar vorgezeichnet, und ihn den Studierenden kenntlich zu machen, ist der Hauptzweck dieses Buches, im Gegensatz zu den eklektischen Sammlungen eines oft recht heterogenen Tatsachenmaterials in vielen älteren Lehrbüchern.

El cretacico inferior del Nordeste de Iberia

On the occasion of the III Colloquium on the Cretaceous of Spain, which took place in More-lla on the 6th, 7th and 8th September 1991 sponsored by the Spanish Group of Mesozoic, there were two field trips to illústrate the present knowledge of the Lower Cretaceous of Northeastern Iberia. These excursions are the object of the present guide-book. In the period passed between when this guide-book was written and its final publication, new results were published which represent a significant increase in our previous knowledge. These publications in international journals, which are referenced at the end of the foreword, together with the figure captions of this guide-book, which have been translated in English, will help the English reader to obtain the information necessary to understand the Lower Cretaceous of Northeastern Iberia.

Elements of mineralogy. Emphasizing the variations in minerals

One purpose of this book is to advance the idea that many minerals are not fixed and simple in composition. Some years ago Professor D. Jerome Fisher of the University of Chicago pointed out that the writer's Elements of Optical Mineralogy had made such a treatment available to advanced students for some years, but that no elementary textbook, in any language, presented the subject in a similar way. A result of Dr. Fisher's suggestion has been the preparation of this volume.

Elements of optical mineralogy. An introduction to microscopic petrography. Part III. Determinative tables

During the ten years since the publication of the second edition of these tables many new minerals have been described. About fifty of these are included in the third edition of Part II,  which was published in 1933, while nearly seventy are of more recent date. The author has attempted to include in supplementary tables in this printing all the new minerals which seem to be well established and adequately described as to their optical properties. Unfortunately it has not been feasible to incorporate them in the main tables, but this is probably not a very serious difficulty since the minerals in question are all very rare.

It is hoped that the use of colored paper for the table (III) classifying minerals on the basis of their color (and pleochroism) in thin section will make it easy to find the various tables quickly and conveniently

In the preparation of this printing the author has benefited by the assistance and encouragement of his wife, Florence S. Winchell.

Emplacement and exhumation of the Kuznetsk-Alatau basement (Siberia): implications for the tectonic evolution of the Central Asian Orogenic Belt and sediment supply to the Kuznetsk, Minusa and West Siberian Basins

New geochronological data [zircon U ⁄Pb, titanite fission-track (TFT) and apatite fission-track (AFT) dating and apatite (U-Th-Sm)/He thermochronology] and thermal history modelling yield constraints on the development of the granitoid basement of the Kuznetsk-Alatau Mountains, southern Siberia. The final stages of magmatism in the Kuznetsk-Alatau palaeo-island-arc are Late Cambrian, and collision of the arc with Siberia occurred in the Early Ordovician. The basement was exhumed by the Early Devonian. Continuous Devonian–Early Triassic sedimenta-

tion filled the adjoining Kuznetsk and Minusa basins and buried (and re-heated) the Kuznetsk-Alatau basement. After initial Pangaea break-up and Siberian flood-basalt magmatism, the basement reached TFT and AFT retention-temperatures in the Middle Triassic and Early Cretaceous, respectively, during denudation-induced cooling.
