Abstract
We have studied the main factors that effect consolidation of terrigenous rocks. The porosity of mudstones of the Nepa Formation (Siberian Platform) is shown to reflect the maximum pressures under which the rocks existed throughout their geologic history. It can be used for regional paleotectonic analysis. The porosity of sandstones depends on much more factors operating both on sedimentogenesis and on subsequent catagenesis of the rocks; the major of them are the depths of the maximum burial of sediments, the size of mineral grains, and the intensity and time of secondary cementation of rocks.
