Palaeozoic and Cenozoic reef formation. An attempt in comparative analysis

An article contains a comparative analysis of the Palaeozoic and Cenozoic reef formation, mainly in terms of the position of reefs in the basins of continental and oceanic blocks. It is shown that in the Cenozoic the main formation of reefs took place directly in the oceans, including at the boundaries between oceans and continents, and, to an extremely limited extent, in the basins of the continental segment. In the Palaeozoic, along with oceanic reef formation, there was intensive development in extensive basins of the continental block. This is one of the manifestations of the general evolution of carbonate accumulation, when the Palaeozoic carbonate sediments were formed in similar shallow water bodies that covered very significant surfaces of the continents.
