Authigenic calcite-dolomite series carbonates of lacustrine bottom sediments: morphology, geochemistry, and mineralogy (South of Western Siberia)

Identifying the features of modern mineral formation is currently an urgent problem. On the example of small lakes in the South of Western Siberia, authigenic calcite-dolomite (Cal-Dol) minerals of various magnesia degrees are considered. Modern mineral formation occurs on the background of demolition of terrigenous and organic matter accumulation in the sediments. The morphology, geochemistry and mineralogy of authigenic Cal-Dol minerals are considered
