Abstract
A section of Upper Carboniferous and overlying Jurassic sediments in the area of a buried karst depression in the northwestern part of Moscow was studied. According to conodont zoning, it was revealed that in the section of the karst depression the Perkhur Formation directly lies on the Voskresensk Formation altered by karst processes. It was shown that the absence of the Neverovo Formation in the section is associated with landslide deformations, which occurred in the Middle Jurassic (Kudinovo) time, that is, the movement of a block of the Perkhurovsky limestones, which was located hypersometrically higher on the slope of the karst paleodepression.
