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 c

Introduction. Concepts describing bacterial effects on mineral formation and, first of all, on the formation of carbonate deposits, started to appear late in the 19th century both in Russia and globally. The precipitation of materials was demonstrate

There are five great cycles of reef formation in Paleozoic — Early Cambrian, Middle—Late Ordovician, Silu-rian—Devonian, Late Visean—Serpukhovian and Permian. Their upper limits are determined by the corresponding periods of biotic crises and

In a complex and diverse reef community composition the biogenic nature of the deposition of the carbonate material is the most evident. Biotic crises, after which a significant evolutionary update of the organic world took place, also affected sedim

Oil- and gas-bearing reefs are widespread in the Paleozoic of ancient (North American, East European, and Siberian) platforms. Two main types of reefs have been identified according to their morphology and paleogeographic position. Single isolated re

An ultramicroscopic study of tubiphytes—tubular formations, composed of pelitomorphic calcite from the Lower Permian Tra-Tau reef (Cis-Urals)—was carried out. A multilayer structure of the walls was recognized. The inner layer is an ultrathin lay

Carbonate deposits of tidal zones are characterized by micritic structures, considerable content of clay material, wide development of cyanobacterial formations. Under arid climate conditions, dolomite tidalites are formed in association with evapori

Carbonate sediments in tidal zones are characterized by microgranular textures, insignificant content of the clayey material, and abundance of the cyanobacterial formations. The arid climate fosters the formation of dolomitic tidalites in association

Paleozoic reef formation developed cyclically, and its global termination has been caused by the biological reasons — biotic crises and mass extinctions near the borders early and middle Cambrian, Ordovician and Silurian, Frasnian and Famennian, Se
