(1999)Ti-biotite megacrysts, glimmerites, and intergrowths of biotite, clinopyroxene, and ilmenite megacrysts were found in Quaternary basanites and Miocene picrobasaltic tuff of the Vitim Plateau. The TiO2 content in the micas ...
-
(2003)Paired apatite fission track and U-Th/He dates provide the first Late Cenozoic cooling ages for the northern Tien Shan. These data clearly argue for pulsed deformation since the Late Miocene, with early (11–10 Ma) and late ...
-
(2001)Carbon isotopic composition was studied in oils and hydrocarbon gases from different oil and gas fields and reservoirs hosted in the Upper Cretaceous to Upper Pliocene sequences of the South Caspian mega-depression. It was ...
-
(2003)The transition from the Early Miocene to the Middle Miocene is a crucial point for the development of mollusc faunas (gastropods and bivalves) in the Central Paratethys. Here, we first discuss the confusing and partly ...
-
(1988)To reconstruct the evolution of the climate, the authors mapped its zoning on the basis of planktonic forminifera characteristic of the end of the middle and the end of the late Miocene. The position of climatic zones in ...
-
(2006)Structural evolution of the Kamchatka-Aleutian junction area in late Mesozoic and Tertiary was generally controlled by (1) the processes of subduction in Kronotskiy and Proto-Kamchatka subduction zones and (2) collision ...
-
(2003)Comparative characteristic of spore-pollen assemblages from the Son'e (late Eocene), Bui, Svetlovodnaya (late Eocene-early Oligocene), Amgu (late Oligocene-early Miocene), Dembi, Velikaya Kema (late early Miocene-earliest ...
-
(1999)According to the present day knowledge, the stratigraphic equivalents of the Early Miocene volcanic rocks of Sakhalin in the East Sikhote-Alin must be the rocks of the Dembi Suite, a constituent of the Kizinsky Formation ...
-
(1999)The Early Miocene volcanic rocks of Sakhalin, constituents of the Chekhov Formation, are separated from the older Late Paleogene volcanics (phase I of Cenozoic volcanism) by a thick normal sedimentary sequence and, hence, ...
-
(2002)Upland and shield areas of central and northwestern Europe are characterised by an abundance of relict weathering mantles (saprolites). These saprolites, if accurately dated and interpreted, may serve as an important ...
-
(2001)Mineralogical discrimination of iron oxides in soils and sediments is not a trivial task, mainly because of their small grain size and low concentration. With mineral-magnetic techniques, highly magnetic ferrimagnetic ...
-
DIAGENETIC AND CATAGENETIC PRODUCTS OF ISORENIERATENE: MOLECULAR INDICATORS FOR PHOTIC ZONE ANOXIA (1996)A wide range of novel diagenetic and catagenetic products of the diaromatic carotenoid isorenieratene, a pigment of the photosynthetic green sulphur bacteria Chlorobiaceae, has been identified in a number of sedimentary ...
-
(1989)One of the tasks of the 21st cruise of the RV Yevpatoriya in the Black Sea in 1988 was to search for accumulations of gas hydrates supplied by an underwater mud volcano, and inferred to exist there by analogy with those ...
-
(2001)The rodent assemblage from the Middle Members of the Chul’adyr Formation contains seven species that belong to six (sub)families. The dominant Cricetidae are represented by a new genus and species:Aktaumys dzhungaricus and ...
-
(2004)The Aral Faunal Assemblage is rich in small mammals. Insectivores there include the hedgehogs Galerix sp., Exallerix efialtes Lopatin, Amphechinus akespensis Lopatin, A. microdus Lopatin, and Amphechinus sp.; the moles ...
-
(2006)The purpose of this paper is to document the influence of depositional environments on shallow-water, low-relief clinoforms from the description of five ancient carbonate platforms: the Neoproterozoic (Namibia), Middle ...
-
(2006)The selection of the disposal site is probably the most important step in the development of solid waste management. In site selection, geology plays a determining role. This study evaluates the characteristics of the ...
-
(2000)New high-resolution seismic reflection data from the central part of Lake Baikal provide new insight into the structure and stratigraphy of Academician Ridge, a large intra-rift accommodation zone separating the Central ...
-
(1995)In oils and Precambrian- to Miocene-age source rocks from varying depositional environments, we have conclusively identified several novel 3-alkyl sterane and triaromatic steroid series, including (1) 3β-n-pentyl steranes, ...
-
(1996)Lherzolite xenoliths in Miocene to Pleistocene basalts from five sites in the Hamar-Daban range in southern Siberia provide sampling of the mantle close to the axis of the Baikal rift. These anhydrous spinel lherzolites ...
