Age and patterns of karst distribution at the Pikalevskoye fluxing limestone deposit
Authors:
Abstract
The Pikalevskoye deposit of fluxing limestone (Leningrad Region) is located within the so-called Carboniferous plateau. The productive strata of the deposit is represented by organogenic, crystalline and dolomitic limestones and dolomites of the Tarussky and Venyevsky horizons of the Visean Stage, which in the western part are overlain by Quaternary moraine and lake-glacial deposits with a thickness of 6 to 30 m, and in the east also by terrigenous carbonate rocks of the Steshevsky horizon of the Visean Stage and dolomites of the Protvino horizon of the Namurian Stage.
