Paragenesis of Micro - and Nanominerals as Indicators of Fluid-Dynamic Conditions of Soil Formation in Oil and Gas - Bearing Intermountain Mud-Volcanic Depressions of the Baikal Region

It is shown that the soil is a mineral petrographic facie of endogenous-exogenous oil and gas bearing lithocomplexes of mud volcanoes in the South Siberian region, which belong to the fluid-dynamic systems of modern Earth degassing pipes. The fluid-dynamic regime of the latter determines wide variations of thermodynamic, physic-chemical, and geochemical conditions of soil formation. It has been established that mineral associations are formed thus and can be used as soil-genetic indicators. A number of the mineral paragenesis of soil formation fluid-dynamic conditions is identified: fluid-pyrometamorphic one, appeared during recovered gases strong oxidation and natural cracking of liquid oil; fumarole steam gasous one; heterogenization products of hot springs hydrotherm; hydrothermal-sedimentary chemogenic one involving bacterial communities.
