9.3.2: Hydrothermal Ore Deposits
9.3.2.1 Porphyry Deposits. Porphyry deposits are a special kind of hydrothermal deposit. They form when hydrothermal fluids, derived from magmas at depth, carry metals toward the surface and deposit minerals to create disseminated ore deposits. These deposits are important sources of copper, molybdenum, and gold.

Mineral deposit | Definition, Examples, & Facts | Britannica
A mineral deposit that is sufficiently rich to be worked at a profit is called an ore deposit, and in an ore deposit the assemblage of ore minerals plus gangue is called the ore. All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term.

Reading: Classifying Minerals | Geology
Minerals are classified according to their chemical properties. Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–.

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.
