Abstract
Sediment-hosted copper deposits in Kazakhstan are hosted by red-colored sandstones and shales of Silurian to Permian-Triassic age. All of the mineable deposits (Dzhezkazgan, Zhaman-Aibat, and Zhilandinskaya group) are localized by syndepositional brachy-anticlines within Permian-Carboniferous red-colored formations of the Chu Sarysu basin. The location and paragenesis of these copper deposits is related to the accumulation of petroleum and natural gas. Numerous sediment-hosted copper occurrences in other regions are related to disseminated coalified organic matter in red-colored sedimentary rocks that formed small centers of copper-accumulation and scattered copper mineralization.
