Studies of black bituminous dolomites and shales in the Republic of Uzbekistan, which contain noble, rare, and trace metals, uranium, and lithomedicinal extracts have shown that metallic and non-metallic minerals are saturated with organic matter and are located in the form of amorphous and coalified inclusions. Part of the organic matter in the rocks was in a solution of seawater and fell into the sediment by adsorption of dissolved organic molecules of mineral particles that settled to the bottom. Organic bituminous black and dark gray dolomites are fossils formed from the bottom sediments of seas and lakes with inclusions of gaseous fluids, represented from dry gas to condensate gases, into which many organic and inorganic substances can pass when a certain temperature, volcanic activity, pressure, and tectonic movements are reached (Turamuratov IB et al. Scandium – metal of the XXI century. Sс – potential of world and Uzbekistan. Geology and mineral resources. Uzbekistan. Tashkent. No. 3, pp. 31–43, 2021). It is believed that black, organic matter-rich dolomites and shales were deposited in very calm conditions, of intercontinent or adjacent tectonically stable continental blocks. Some of the richest and largest deposits probably formed in the marginal part of these areas, apparently in an environment of pre-rock stability. Gold and uranium accumulated syngenetically with the sedimentary process. Marine waters could be enriched in dissolved uranium to a large extent due to nearby volcanic activity or as a result of intense weathering under oxidizing conditions of granites, which served as a source of gold and/or uranium rare earth elements. These metals could also be extracted from seawater by organic matter, phosphate minerals, pyrite, or colloidal clays under reducing conditions (Raymond and Coveny in Metalliferous paleozoic black shales and associated strata. Geochemistry of sediments & sedimentary rocks, pp. 135–144).
