-
(2001)The Azov Region and adjoining areas are rich in sedimentary successions that have yielded abundant remains of fossil mammals. These encompass the time span from Late Miocene through late Pleistocene. The occurrence of some ...
-
(2004)The two rock-forming polymorphs of serpentine Mg3Si2O5(OH)4, lizardite and chrysotile, occur in nature in virtually identical ranges of temperature and pressure, from surficial or near-surficial environments to temperatures ...

(2004)
-
(1997)The study of Pliocene-Quaternary sediments of the Kamchatskii Cape and the paleoecologic analysis of associated mollusks and foraminifers resulted in distinguishing the early and late Ol'khovaya transgressions. During the ...
-
(2006)Large seasonal variations in the dissolved load of the headwater tributaries of the Marsyandi river (Nepal Himalaya) for major cations and 87Sr/86Sr ratios are interpreted to result from a greater dissolution of carbonate ...
-
THE SIGNATURES OF TECTONICS AND GLACIAL ISOSTATIC ADJUSTMENT REVEALED BY THE STRAIN RATE IN EUROPE (2004)Tectonics and glacial isostatic adjustment (GIA) are simultaneously taken into account in order to quantitatively define their role in crustal deformation in Europe. A spherical finite-element model, based on the thin ...
-
(1993)Carbon-isotope analysis of CO2 has been undertaken on pure mineral separates from six cordierite-bearing assemblages from Kerala, South India, to identify the significance of fluid inclusions and channel-trapped volatiles ...
-
(2004)Enclaves are often incorrectly used to measure magmatic strains in plutons. We emphasize that microgranitoid enclaves are not like other ellipsoidal markers used to determine strain for the following reasons. (1) Adjacent ...
-
(2003)Large diamonds (10–200 carats) from Udachnaya, Mir, and Aikhal kimberlite pipes of Yakutia contain variable mineral inclusions typical of diamonds of smaller size. Among these inclusions, extracted from outer portions of ...
-
THE SIGNIFICANCE OF MULTIPLE SATURATION POINTS IN THE CONTEXT OF POLYBARIC NEAR-FRACTIONAL MELTING (2004)Experimental petrologists have successfully located basaltic liquid compositions parental to mid-ocean ridge basalt that are, within experimental resolution, multiply saturated with three-phase harzburgite or four-phase ...
-
(2004)Amphigraptus divergens Lapworth is known to be restricted, in Britain, to the linearis Biozone, and its occurrence in the type Ashgill Series reinforces Rickards' prior independent attribution of that part of the type ...
-
(2003)All previous versions of a physically based land-surface model SWAP have assumed for simplicity that vegetation is fully covered by snow during the cold season. Such assumption is reasonable only for the regions dominated ...
-
(1997)The review and recalculation of all experimental data on the solubility of quartz and amorphous silica in liquid water and saturated vapour along the lower three-phase curve up to the critical end-points give the relation: ...
-
(1996)Pyrite framboids are densely packed, generally spherical aggregates of submicron-sized pyrite crystals. In this study, a survey was made of framboid size distributions in recently deposited sediments from euxinic (Black ...
-
(2001)The cranial anatomy of Orlovichthys limnatis, a Famennian, Late Devonian dipnoan from the Orel region of central Russia, is described on the basis of an almost completely preserved skull, a mandible, and numerous elements ...
-
(2001)An almost complete skull with teeth of Archaeoryctes euryalis sp. nov., one of the earliest members of the family Didymoconidae, is described from the Tsagan-Khushu locality in Mongolia (Upper Paleocene, Naran Bulak ...
-
(2003)Carbonatite and alkaline magmatism repeatedly occurred within the southwestern Siberian Platform and its folded surrounding during Late Riphean, Early-Middle Paleozoic, and Late Mesozoic. The least determined is the timing ...
-
(1996)The Sm-Nd isochron age was defined for rocks from various associations which make up part of the ophiolite assemblage of the Ozernaya zone of the early Caledonides. The age of gabbroids and tholeiite basic rocks of the ...
-
(1989)The solidus for a fertile peridotite composition (“Hawaiian pyrolite”) in the presence of CO2 has been determined from 14 to 35 kbar. The solidus shape inP-T space is consistent with previous studies in the model system ...
-
(2004)Abyssal tholeiite is generated by partial melting of the upper mantle. The mantle sections of ophiolite complexes show that partial melting leaves mantle residua that are lherzolitic or harzburgitic, harzburgite being the ...
