(2003)The Ordovician iron oolites in Baltoscandia are generally geographically extensive but lean, [The oolites were formed during the period of the highest global iron oolite production ever. Most of the major oolites from this ...
-
(2002)One of the most complete sections of Permian deposits in the southern Urals is described. It spans the middle Asselian-Artinskian interval and yields fusulinids, ammonoids, and conodonts. The upper half of the Uskalyk ...

(1995). 30 species of fusulinids belonging to 14 genera: Pamirina, Boultonia, Quasifusulina, Darvasites, Rugosofusulina, Darvasella, Dutkevitchia, Robustoschwagerina, Zellia, Alpinoschwagerina, Chalaroschwagerina, ...
-
(2001)Recent diffusion modeling of eclogitic garnets from the Great Caucasus, Russia, and Yukon, Canada, have shown that the preservation of garnet growth zoning in rocks that have equilibrated at high temperature (680–700 °C) ...
-
(1998)Apatite-dolomite carbonatite at Lesnaya Varaka, Kola Peninsula, Russia, hosts intricate mineral intergrowths composed of lueshite in the core and pyrochlore-group minerals in the rim. Lueshite is a primary Nb-bearing phase ...
-
(2001)Of the terrestrial archives, loess–palaeosol sequences provide a most complete record of climatic change. This may be compared with the Marine oxygen isotope stratigraphy, and may help in the reconstruction of past atmospheric ...

-
(2001)The purpose of this study was to assess, for the first time, the presence of muramic acid (Mur) and 3-hydroxy fatty acids (3-OH FAs), chemical markers for terrestrial bacteria in ''curated'' lunar samples by use of ...
-
(1998)The rare earth elements (REE) and selected other trace elements were measured in plagioclase and pyroxene from nine samples of the lunar ferroan anorthosite (FAN) suite of rocks. Samples were selected from each of four FAN ...
-
(2004)Studies of lunar meteorite Dhofar 026, and comparison to Apollo sample 15418, indicate that Dhofar 026 is a strongly shocked granulitic breccia (or a fragmental breccia consisting almost entirely of granulitic breccia ...
-
(2001)Indigenous lunar nitrogen composition and abundances have been determined in old ferroan anorthosite 60025 and in anorthositic breccia 67915 from North Ray Crater, as well as in 55 cm deep volcanic glasses of 74001 ...
-
(2003)Dhofar 287 (Dho 287), a recently found lunar meteorite, consists in large part (95%) of low-Ti mare basalt (Dho 287A) and a minor, attached portion (˜5%) of regolith breccia (Dho 287B). The present study is directed mainly ...
-
(2004)Accurate estimates of global concentrations of Th, K, and FeO have an important bearing on understanding the bulk chemistry and geologic evolution of the Moon. We present empirical ground-truth calibrations (transformations) ...
-
(2004)Taphofloras of the Koryak Upland and the Sagwon Locality of North Alaska are described in terms of their taxonomic composition, stratigraphic ranges, and comparison with coeval floras of Northeastern Russia and Alaska. ...
-
(1995)MacFlinCor was developed to process laboratory data gathered on fluid inclusions and to calculate isochores for geologically important fluids composed of H2O, CO2, CH4, NaCl, and N2. Within the program, interactive diagrams ...
-
(1987)The recent additions to the lists of meteorite craters discovered on the Earth's surface are mainly impact-induced structures over 1 to 3 km in diameter [1-3]. This paper describes the identification and study of another ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2019)Inter-well measurements are used to reduce drilling costs with no reduce small kimberlite body detection. The radio wave method enables measurement of the apparent absorption coefficient that is proportional to the effective ...
-
(2003)The isotopic composition of carbon and oxygen was determined by two techniques in whole-rock samples and single grains of carbonates from rocks of various morphogenetic types from the Aldan Shield. The isotopic values ...
