-
(2001)A carbon and sulfur isotope mass balance model has been constructed for calculating the variation of atmospheric O2 over Phanerozoic time. In order to obtain realistic O2 levels, rapid sediment recycling and O2-dependent ...
-
(1995)It has been shown that molecular nitrogen (N2) in natural gas accumulations can result from thermal maturation of coal and other forms of sedimentary organic matter. The present paper investigates the loss of coal nitrogen ...
-
(1989)The authors have discovered in the Katanga-Tetere interfluve extensive reserves of mordenite, produced by post-sedimentary transformation of ashy tuffs of intermediate composition. The particle-size distribution of the ash ...
-
(2004)Morphological and histological aspects of conodont element regeneration are considered on the basis of material from the Late Devonian and Early Carboniferous. It is shown that the regeneration mechanism of conodonts ...
-
(2001)The systematic position of a peculiar group of Angaran gymnosperms usually treated as "cordaites" is discussed. The systematics of these plants related to coniferophytes remains uncertain because of their extreme peculiarity. ...
-
(2001)Three new species of Carboniferous brachiopods from the orders Spiriferida and Spiriferinida are described. There species belong to three different families: Anthracospirifer solenensis belongs to the Spiriferidae (subfamily ...
-
(1985)Episodic volcanism favors, as shown by examples from Europe, the USA, and Brazil, the formation of organic-rich sediments (hydrocarbon source rocks). The examples examined from Europe comprise the Lower Carboniferous ...
-
(2003)Paleomagnetic measurements were made on samples from Silurian, Devonian, Carboniferous and Permian aged rocks from the Omulevka terrane, northeast Russia. The Omulevka terrane is a fragment of continental margin that forms ...
-
(1989)Gabbro-monzodiorite plutons in different parts of Mongolia are lumped together with the granitoid bodies intruding them into the gabbro-monzonite-granosyenite, monzonite-granosyenite-granite and other rock associations, ...
-
(1998)Four new species of schwagerinids are described from the Carboniferous/Permian of the Fore-Urals (Perm Region): Rugosofusulina larga, R. gubachica (Rugosofusulinidae), Sphaeroschwagerina visherensis (Pseudoschwagerinidae), ...
-
(2001)Three new schwagerinid species of the genus Praepseudofusulina, i.e., P. gemma, P. bullula, and P. arsenii, are described from the Upper Carboniferous (Gzhelian Stage, Daixina bosbytauensis-Globifusulina robusta Zone) of ...
-
(1990)The silver-gold sulfide investigated by the authors, uytenbogaardtite, was discovered in part of a gold-bearing quartz vein in the oxidation zone of one gold-silver deposit in western Uzbekistan, where the primary ore is ...
-
(1990)This paper attempts to fill the gap for some metasomatites from western Uzbekistan, where they accompany rare-metal mineralization. The ore field in which we worked consists of Carboniferous sedimentary and volcanosedimentary ...
-
(2001)Revision of the type material of dispersed cordaitean fructifications of Krylovia Chachlov 1939 supports previously proposed morphological interpretation and its identity to the genus Samarospadix Neuburg, 1948 from the ...
-
(2001)Project No. 369 ("Comparative Evolution of PeriTethyan Rift Basins") of the International Geological Correlation Program produced a new palaeotectonic-palaeogeographic atlas of the western PeriTethyan domain. The atlas ...
-
(2003)In the WNW-ESE Donbas fold belt (DF), inversion of 3500 microtectonic data collected at 135 sites, in Proterozoic, Devonian, Carboniferous, and Cretaceous competent rocks allowed reconstruction of 123 local stress states. ...
-
(2003)Three new Middle–Late Ordovician and two new Early Carboniferous paleomagnetic poles have been obtained from the North Tien Shan Zone (NTZ) of the Ural–Mongol belt in Kyrgyzstan and Kazakhstan. Paleolatitudes for the ...
-
(2002)Because of a depositional hiatus, Late Carboniferous corals are unknown from the eastern Cimmerian Continent. Early Permian (Asselian to Artinskian) corals are characterized by non-dissepimented solitary forms, and the ...
-
(2004)Permo-Carboniferous rifting in Europe was accompanied by the widespread emplacement of mantle-derived magmas forming regional dyke swarms and sills in northern England, Scotland, Norway and southern Sweden during the late ...
-
(2003)The Carboniferous succession in the Donets Basin hosts about 130 seams, each with a thickness over 0.45 m. Nine economically important seams from the (south)western Donets Basin are studied using organic petrographical, ...
