Next evolutionary transforming folded buildings can be recognized in the Earth history: 1) transforming areal tectonotype to directive-linear one, 2) increasing of a newly formed (suprucrustal, juvenile) complexes folded structures and their composition, 3) decreasing of time generation (geotectonic cycles), grade of rocks metamorphism and intensity of granite-forming processes.

Rift (neocomian-barremian) and platform (aptian-paleogene) stage of development can be defined for the Muglad and Melut basins of South Sudan on rate of their subsidence.

This article explores the main development stages of metallogeny in Russia and abroad.

Complex of methods for the forecasting of deeply buried endogenetic mineralization as a result of lithogeochemical sampling of soils. The main attention is stressed for the elements of indication, sampling, methods of analysis and methods of evaluation.

The work was in making the analysis of Gold and its trace-elements distribution. The analysis of geo-chemical features of the northern flank of Mayskoe deposit, belonging to Altae-Kyznesko-Zapadno-Saianskyi volcano-plutonic belt of the age frames from posterior Pre-Cambrian to anterior Paleozoic, allocated at the boundary of Gornaya Shoria and Gornyi Altai, was made in 3D space. 3D geochemical model of the northern flank of the deposit was made in accordance with the gained data.

Basing on geological data and special analyses of distance Earth researches data combined with series of geophysical data interpretation, the geological-geophysical model of Telbes region, located in early-middle volcano-plutonic belt, has been produced, where paleovolcanic strucure is easily recognisable.

Problems of the correlation between the geological complexes composition and Earth crust structure are discussed using some original diagrams.

The article devoted to factors, which influence on subsoil hydrocarbon concentration, and also to finding out principles and quantities of concentration changes.
