(1993)
-
(2004)Based on the study of the Tsentral'noe deposit, specific features of the formation of mineral assemblages of complex titanium–zirconium placers are considered. The placers formed during the multiple redeposition of clastogenic ...
-
(2002)The discipline of organic geochemistry is an outgrowth of the application of the principles and methods of organic chemistry to sedimentary geology. Its origin goes back to the last part of the nineteenth century and the ...
-
(1997)A detailed study of size distributions of framboidal pyrite in Holocene Black Sea sediments establishes the timing of a change from deposition under an oxic water column to deposition under an anoxic and sulfidic water ...
-
(2005)На основании анализа возможных распределений компонент ксенона, азота и углерода между двумя популяциями зерен алмаза метеоритов Orgueil CI и Allende СVЗ сделаны следующие выводы о свойствах популяций зерен наноалмаза в ...
-
(2002)The study of Holocene deposits on Iturup Island is very important for understanding palaeolandscape changes on the island. It is separated by deep straits from the neighbouring islands and was isolated during the last ...
-
(2003)We investigate the geometry and kinematics of Holocene active compressional structures in the Mondy basin and its surroundings (western termination of the Tunka system of rift basins) and continue the discussion on the M ...
-
(2004)Peatlands provide a widespread terrestrial archive of Holocene environmental change. The taphon omy of peat is relatively simple, the range of evidence and proxies is wide, and dating methods have become more accurate and ...
-
(2000)Areal interpretation of air photographs was carried out for the Koryak Autonomous District (KAD) which includes the northern part of Kamchatka and the southern Koryak Highlands (ca. 240 000 km2) to locate young (Holocene) ...
-
(2003)Synthetic glacier length records are generated for the Holocene epoch using a process-based glacier model coupled to the intermediate-complexity climate model ECBilt. The glacier model consists of a mass-balance component ...
-
(2004)Radiocarbon-dated pollen, rhizopod, chironomid and total organic carbon records from Nikolay Lake (73°20’N, 124°12’E), complemented by a pollen records from nearby peat sequence, provide the detailed environmental ...
-
(1996)On the basis of new factual material, the history of the formation of the Prebaikalia vegetation cover is considered. For this purpose data of palynological analysis for nine sections of lacustrine-palustrine deposits were ...
-
(2002)The primary aim of this paper is to describe and discuss the palaeoclimatic significance of mid-to late-Holocene fields of raised-beach ridges at Matalaniemi and sea-ice-pushed boulders at Kutovaya Bay on the Kola Peninsula. ...
-
(2004)The mineral and chemical compositions and physical properties of diatomaceous clayey–siliceous sediments in the Sea of Okhotsk are studied. Absolute masses of silica accumulation are determined. Their compositional model ...
-
(1998)Based on the study of the mineralogy, chemistry, and particle size of late Pleistocene tephra from the marine and alluvial terraces of southern and central Kunashir I., five tephra groups were identified: four of these ...
-
(2004)Pollen, stomata, and macrofossils in a lake core with a basal date of 9700 14C BP were used to reconstruct past changes in climate and vegetation in the arctic tree line area, northeast European Russia. A palsa peat profile ...
-
(2004)Ostracods secrete their valve calcite within a few hours or days, therefore, its isotopic composition records ambient environmental conditions of only a short time span. Hydrographic changes between the calcification of ...
-
(2002)The pollen stratigraphy of an ombrotrophic patterned ridge-hollow raised bog in the Salym-Yugan Mire Area in boreal West Siberia (60°109N, 72°509E) covers the entire Holocene period. Pollen data from three parallel peat ...
-
(2002)Examples of Holocene-historical volcanism in the territory of Armenia and adjacent areas of Eastern Anatolia and Western Iran are discussed. Holocene-historical activity is proved for the volcanoes of Tskhouk–Karckar, ...
