Evolution of properties of placer-forming minerals in the process of migration
Authors:
Abstract
During the complex pathway from bedrock sources to placers, hypergenetically stable minerals (gold, platinum, cassiterite ilmenite, pyrope, diamond, etc.) evolve with noticeable changes in many properties. The main factors are strength selection among individuals of the same mineral species, mechanical activation of the surface of grains during their grinding, removal of impurity elements, partial dissolution and re-deposition of mineral matter.
