Ore genesis

This is on fairly steep hillside, but it is strange that a prospect pit has not been dug here. Skarn deposits are another manifestation of intrusive-related deposits. Commonly, copper is either formed within sedimentary rocks, or associated with igneous rocks.

The gold is transported up faults by hydrothermal waters and deposited when the water cools too much to retain gold in solution. Metamorphic processes also control many physical processes which form the source of hydrothermal fluids, outlined above. The process of forming nickel laterite deposits is essentially similar to the formation of gold laterite deposits, except that ultramafic or mafic rocks are required.

Radon is a common problem during mining of uranium as it is a radioactive gas. MVT and similar styles occur by replacement and degradation of carbonate sequences by hydrocarbonswhich are thought important for transporting lead. Sedimentary copper forms within ocean basins in sedimentary rocks.

These metal-bearing complexes facilitate transport of metals within aqueous solutions, generally as hydroxides, but also by processes similar to chelation. Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust.

Often ore deposits are classified after examples of their type, for instance Broken Hill Type lead-zinc-silver deposits or Carlin-type Gold deposits. This may occur without much hydrothermal fluid flow, and this is typical of podiform chromite deposits.

Sedimentary copper forms within ocean basins in sedimentary rocks. This scheme, proposed by Waldemar Lindgren classified hydrothermal deposits as hypothermal, mesothermal, epithermal, and telethermal.

Vuggy silica is prevalent in this type of deposit, and massive lower-grade gold ore.

The foundations of hydrothermal processes are the source-transport-trap mechanism. The diagram below is from the paper and depicts clearly how High-Sulfidation VMS deposits form in shallow water near the shoreline of an ocean or brine lake.

This will be described further on the Exhalite page, but jasperoid beds occur prominently on the Prospect, and it is believe each and every one is the edge of a VMS deposit.

It is believed this is the source of the gold for the high sulfidation gold deposit. Hydrothermal processes These processes are the physico-chemical phenomena and reactions caused by movement of hydrothermal waters within the crust, often as a consequence of magmatic intrusion or tectonic upheavals.

Ore genesis. The various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore genesis theories are very dependent on the mineral or commodity.

Ore genesis theories generally involve three components: source, transport or conduit, and trap.

It is believed the size of the orebodies in brecciated arkose (the Whitetail Formation) in Area 1 have the potential to be much larger than the ones beneath the basalt because of.
