Described mineral assemblages indicate changes in geochemical conditions during the bitumen and copper mineralization formation. Tectonic processes, which occurred in the rift environment, created favorable conditions for the ore-bearing solutions migration. It can be assumed that the original copper and hydrocarbons transfer carried in the fluid, and copper and bitumen in the rocks were formed at the same time. Epigenetic process of copper deposition from solutions occurred as a result of the reduction process under the action of gases (Corg, CH4). |
