Biohermic bioclastic (detrital) lithofacies are distinguished composition. types represented by bryozoans coral framestones rudstones, tubiphytes packstones, palaeoaplisyna boundstones rudstones. Granular or fusulinid, crinoid-fusulinid grainstones, bryozoans-tubiphytes crinoid polybioclastic packstones wackstones. Polybioclastic grainstones predominate section Lower limestones. In part section, at base shikhans, there lithofacies. These limestones make up shihan Toratau. Coral common shikhan Yuraktau upper part.
