(2002)The distribution and migration history of the genus Fortipecten, a characteristic late Cenozoic bivalve, is evaluated on the basis of specimens from Hokkaido, northern Japan. Fossil occurrences indicate that Fortipecten ...
-
(2002)The accompanying CD-ROM contains a compilation of geophysical, geologic, and tectonic data for the Bering Shelf, the Chukchi Sea, the Arctic margin, and adjacent landmasses. These data sets focus on Alaska, the Russian Far ...
-
(2003)The aim of this paper is to discuss the Late Precambrian rock complexes in the southern margin of the Siberian Craton, associated with the extension. The analysis of the data available suggests two episodes of intracontinental ...
-
(2000)Geological analysis of planets typically begins with the construction of a geologic map of the planets’ surfaces using remote data sets. Geologic maps provide the basis for interpretations of geologic histories, which in ...
-
(1990)In seismic sections of many regions in the world, there are discrete intracrustal wave-guide or inversion layers with low elastic-wave velocities relative to the host rocks. From our model of the development of intracrustal ...
-
(2001)U-Pb age values were obtained on an intrusion of alkaline quartz diorite in the northwestern closing of the Paleoproterozoic Imandra-Varzuga sedimentary-volcanic structure in the Kola Peninsula. The diorite is hosted by ...
-
(1987)An expedition conducted in 1984 by our Institute on the R/V Akademik Aleksandr Nesmeyanov dredged the central part of the Volcano Trench. It lies between the Izu and the Mariana Trenches and is separated from the Philippine ...
-
(2004)Genetic and geological model for the formation of the Kovdor Massif and the accompanying apatite was discussed. Particular emphasis was placed on the distinguishing of reliable sequence of geologic event resulting formation ...
-
GEOLOGICAL AND GEOCHEMICAL COMPARISON OF SOUTHERN URALS AND SOUTH INDIAN CRYPTOCRYSTALLINE MAGNESITE (2004)South Indian and Southern Urals cryptocrystalline magnesites, deposited in similar geological milieu, are broadly comparable in mineralogy and geochemistry. Magnesite mineralisation in South India is mostly associated with ...
-
GEOLOGICAL AND GEOCHEMICAL CONTROLS ON THE SILVER CONTENT (FINENESS) OF GOLD IN GOLD-SILVER DEPOSITS (1991)A compilation of microprobe fineness data and a re-evaluation of bullion production fineness data suggest that the gold fineness model of Fisher (1945) can be updated and applied to a wide range of gold-mineralised ...
-
(2003)Specific porphyraceous biotite-amphibole granites considered rapakivi-like according to texture and rock and mineral compositions have been distinguished among granitoids in the eastern Hovsgol region. The granites are ...
-
(2002)This paper describes the Late Precambrian geologic complexes from the southern margin of the Siberian Craton, associated with the extension epochs. Analysis of the data available suggests that there were two episodes of ...
-
(1996)A classification of geological engineering structures is presented. The hierarchy of such structures is as follows: geological engineering superstructure; megastructure; macrostructure; mesostructure. The taxonomic division ...
-
(2003)The central Pamirs (CP) as an element of the Alpine Afghanistan-Central Pamir-Tashkurgan Fold System (Fig. 1) is characterized by diverse and multistage sedimentation, magmatism, and metamorphism spanning a wide ...
-
(1999)A currently emerging sulfur isotope record for Phanerozoic seawater, based on structurally substituted sulfate in stratigraphically well constrained biogenic carbonates, allows the detailed assessment of secular variations ...
-
(2002)Located at western portion of northern margin of North China craton, the Baotou-Bayan Obo district is one of the most important Fe-REE-Nb and Au metallogenic provinces in China. Presently, about 52 gold deposits and prospects ...
-
(2002)Fullerenes have been reported from numerous terrestrial and meteoritic sources, but only at low concentrations. The occurrences are associated with localized energetic events such as lightning, impacts of extraterrestrial ...
-
(1997)Geological heritage, as part of natural heritage, includes the in situ located geological reference objects (sites) visualising geological phenomena with high information potential. Forty objects of geological heritage of ...
