abstract: Introduction. Until relatively recently, all carbonate rocks have been divided into organogenic and chemogenic rocks. The former group includes those half-composed of skeletal remains, thus representing a biological problem. The group of chemogenic carbonate rocks initially included all carbonate rocks with a crystalline structure. Later, the “chemogenicity” of formation was attributed only to pelitomorphic and microgranular varieties, while pure crystalline structures were recognised as the res
