Classification of Minerals | GlobalSpec
Classification of Minerals. All minerals are classified into polar or non-polar types according to their surface characteristics. The surfaces of non-polar minerals are characterised by relatively weak molecular bonds. The minerals are composed of covalent molecules held together by van der Waals forces, and the non-polar surfaces do not ...

The Classification of Ore Deposits
About the turn of this century interest in economic geology had reached a high level in North America. The thoughtful paper in 1893 by J. H. L. Vogt, of Norway, on injected igneous deposits derived from an igneous source by the process of magmatic differentiation, which was also advanced to account for hot mineralizing waters, drew attention once more to …
hydrothermal mineral deposit

Not included in the classification, but often mentioned is a mineral occurrence. Usually an occurrence is synonymous with a prospect or a …
Mineral deposits: Classification | SpringerLink
His classification makes essentially no attempt,·unlike Lindgren's, to include deposits formed by surface processes. Perhaps the greatest weakness in the Schneiderhöhn classification is the assumption that the mineral content of a given ore deposit furnishes a direct clue to the conditions under which it was formed.

Mineral Deposits: Breccia can serve as a host rock for mineral deposits. Ore minerals may be concentrated within the fractures and pore spaces of brecciated rocks, making it an important target for mineral exploration. Paleontology: In some cases, fossils or ancient organisms can become incorporated into breccia during its formation. …
Classification of Ore Deposits
The genetic classification should ultimately determine the limits of ore deposition in each class by temperature and pressure. Each deposit should be considered as a problem in physical chemistry, and the solution of this problem, with the necessary geologic data, will suffice to fix the mode of formation of the deposit.
