Stratification and structure of rocks of the Mesozoic-Palaeozoic contact zone
In the article features of development of the changed rocks at the border of pre-Jurassic formations and the Western Siberian plateau mantle are characterised. Palaeozoic residual soils widespread within Nyurolskaya, Silginskaya and Tom-Kolyvanskaja structurally facial zones have trinomial stratification: the hydrolysis zone, the leaching zone and the hydration zone. The best collectors are rocks of the leaching zone
