The hypabyssal rocks of the Omgon Range, western Kamchatka, that intrude Upper Albian-Lower Campanian deposits of the Eurasian continental margin belong to three coeval (62.5-63.0 Ma) associations: (1) ilmenite gabbro-dolerites, ...

The Ladoga, Russia, and adjacent Sulkava, southeastern Finland, metamorphic complexes are the two largest "granulite" provinces of the Svecofennian domain. In this area, the domain is composed of outer and inner zones. ...

The conditions necessary for the existence of nucleic-protein life are as follows: the presence of liquid water, an atmosphere, and a magnetic field (all of which protect from meteorites, abrupt changes in temperature, and ...

The process of granitization was studied in a small massif of high-pressure Paleoproterozoic (2.45-2.36 Ga) metagabbro-norites (coronites) of the Belomorian Group at contacts with Bt-Hbl-Kfs-Pl-Qtz gneiss-granites. The ...

The average compositions (including H2O, Cl, F, and S contents) and chemical structure of oceanic mantle plumes were estimated on the basis of the ratios of incompatible volatile components, potassium, and some other ...

We analyze daily variation in earthquake (EQ) occurrence to try to find a correlation with atmospheric tide whose basic period is 24 h exactly. In selection of earthquake ensembles we use a specially developed index of ...

The formal statistical analysis of variations in the basalt compositions for the whole global system of mid-oceanic ridges (approximately 19000 analyses of quenched glasses), including cluster analysis, discriminant analysis, ...

Palynological analysis of surface samples was accomplished within the framework of integrated ecological investigation of northwestern Timan-Pechora oil-and-gas-bearing province (sampling depth, 0.015 m). Palynological ...

Middle Paleozoic magmatism at the eastern Siberian platform was related to riftogenic processes, which were most clearly expressed in the Vilyui Rift and led to the formation of rift depressions filled with sedimentary-v ...
