geological gold deposits of ahafo crust. Mesothermal gold deposits in schist and greywacke, Metals in . These deposits formed by hot water moving through rocks as the surrounding rocks were uplifted from deep (10 km) in the Earth's crust. The metals in the deposits were extracted from the surrounding rocks by dissolving trace amounts from a large volume of rocks. The metals were then deposited ...

These processes mentioned above tend to occur in areas with natural faults that move the earth's crust. This is the reason why most areas that contain the most gold are mountainous regions with constant geological activity going on. Although gold can potentially be found anywhere on earth, the truth is that most gold is found in the more active parts of our planet, geologically speaking ...

· 7. Placer deposits form at Earth's surface when weathering action exposes gold from other, older lode deposits. The gold is swept into, and settles in, streams, lakes, rivers or the sea floor. Many placer deposits are of recent geologic age, but some are billions of years old. In most of Earth's crust, gold concentrations are very low. More

gold deposits throughout the whole Jiaodong Peninsula formed in broadly uniform hydrothermal fluid and physicochemical conditions [12]. Despite these intensive studies, a universal answer is not yet available, and the question of source of the ore fluids and metals is still open, as well as the genesis of gold deposit [22–30].
