Composition and evolution of ore fluids in a magmatic-hydrothermal ...

The relative Cu, Pb, and Zn concentrations in fluid inclusions at Bismark are consistent with those measured from base-metal ores in high-temperature carbonate- replacement deposits throughout Mexico, and suggest that the bulk-metal budget of these deposits is primarily controlled by magmatic-hydrothermal fluids deficient in Cu.

Ore Minerals : What are Ore Minerals? - Geology Page

Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable ...

chemical element - Ore deposits | Britannica

An ore deposit, in its simplest terms, is a portion of the Earth's crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical. Nevertheless, its formation required the operation of geochemical processes to produce the concentration of a specific element or elements in a particular place.

CLASSIFICATION OF DEPOSITS - Earth Sci

Hydrothermal solutions pass along the fault zone and deposit or precipitate the ore and gangue minerals within the open spaces. Thus, the vein is necessarily younger than the rocks that contain it.
