Popis: | In Eastern Transbaikalia, as a result of collision processes during Middle-Late Jurassic, formations of amudzhikano-shakhtaminsky complex (J2-3) has been acquired wide development. The origin of gold mineralization and explosive breccias associated with the final stages of their forming. As a rule, a few stages of the formation of explosive breccias are separated. Marked pre-ore, sin-ore and post-ore breccias differ by the composition of cement and concentrations of ore, rare and rare-earth elements. Magma chambers of early explosive breccias characterized by greater depth and smaller values of their differentiation degree. |
