Oct 17, 2019· Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific. There are two main approaches to mineral deposit classification.

An ore deposit may also form as a result of several steps of processes that are identical but belong to different periods of geological history. Ore deposits are divided into deposits of ferrous, light, non-ferrous, noble, rare, and radioactive metals and deposits of trace elements.

Mining - Wikipedia

Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite ...

Current ore deposit models document the mineralizing processes that lead to hydrothermal ores, their geochemical, mineralogical, and textural footprints, and those of their alteration haloes, their host terranes, and their tectonic settings. Hydrothermal ore deposits subjected to high-grade metamorphism after formation can have world-class tonnages and grades, but nowhere does their ...

Mining in Europe has a very long history. Examples include the silver mines of Laurium, which helped support the Greek city state of Athens.Although they had over 20,000 slaves working them, their technology was essentially identical to their Bronze Age predecessors. At other mines, such as on the island of Thassos, marble was quarried by the Parians after they arrived in the 7th century BC.

Ore deposit | geology | Britannica

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. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Metals are largely derived from the mantle or crust by partial melting and fluid-related leaching. Ligands can be provided from the same sources, or from the atmosphere, hydrosphere and biosphere. Transport is mainly by mechanical or mass transfer mechanisms and by fluids. On and near the surface, biological processes can also concentrate and transport ore components or remove non-ore components.

Geochemistry Geochemical dispersion halos. Primary ore deposits contain primary ores that may develop a geochemical dispersion halo known as primary dispersion expressions. " These primary expressions are syndepositional in nature, and thus can occur at or close to the time of ore formation". Primary ore expressions may show alteration of the host rocks.
