In common rocks, precious metals, such as copper, gold, and silver, are ranked in parts per million or even parts per billion. For us to be capable to obtain these metals, we must find locations where the mineral sources have much higher frequencies. These processes are connected with igneous, sedimentary, and biological methods.
Plate tectonics is sen as the underlying mechanism that leads to the generation of the gold deposits. The majority of them fall into the categories of the lode gold deposits. They are high graded, thin and faulted and are primarily made form the quartz.
The lode deposits have been occurring with the orogeny of the plates that collided with that of the other plate within the geologic history they usually associate themselves the basalts and occupy intrusive igneous rock properties.
Placer deposits are a source of the pre-existing fluvial processes within the river and the streams.
