Annotation Marine and freshwater organogenic carbonates of different ages have been identified in Transbaikalia, both principal and secondary producers have been determined for them. The principal (first) group of producers creates carbonates as a result of their vital activity, the secondary one – with the accumulation and grouting process of skeletal remains (bioclast). The carbonate producers are the representatives of three kingdoms:Cyanobacteria, Fauna (Zoo) (animals) and Flora (Phyta) (plants).The principal producers of organogenic carbonates of Precambrian Transbaikalia are Cyanobacteria, which form such autochthonous structures as stromatolites and oncolites. In the Riphean, along with cyanobacteria, the producers of carbonates are Udokanii that are conventionally referred to as soft cnidarians and represented mainly in the form of a bioclast of colonies (segmented types of skeletons). From the Cambrian onwards, in the Paleozoic, archaeocyatha, cnidarians, mollusks, arthropods, bryozoans, brachiopods, the most part of which is presented in the carbonates in the form of bioclast, have become the producers of organogenic carbonates. There are 6 types of skeletons, which differ in their ability to resist the destruction: covered shells (corals, trilobites), segmental (red algae, archaeocyatha, Udokania, crinoids), branching (corals, bryozoans), chambered (myarians, gastropods, foraminifers, crustaceans, brachiopods, echinoderms), crusted (cyanobacteria, algae, corals, bryozoans) and massive ones (cyanobacteria, cnidarians, some kind of bryozoans). The feature of the Paleozoic carbonates of Transbaikalia is the presence of specific limestone-encrinites consisting of the segments of crinoid columns (segmented group of skeletons). The marine Mesozoic of Transbaikalia is characterized by a slight carbonate formation. In burial places, bioclasts of bivalves predominate in a diffuse or lenticular form with rare gastropods (chamber group of skeletons) confined to terrigenous rocks. Molluscs (myarians and gastropods) and ostracods (chambered group of skeletons) have become the producers of organogenic carbonates in the continental deposits of the Mesozoic in the region.
