Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron , silver , gold , copper , zinc , quartz , and pyrite intermittently from the 1860s until 1963.
Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and produced by volcanic-associated hydrothermal vents in submarine environments. [2] [3] [4] These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits
Iron sulfide concretions, such as the Kansas Pop rocks, consisting of either pyrite and marcasite, are nonmagnetic. [79] On the other hand, iron sulfide concretions, which either are composed of or contain either pyrrhotite or smythite , will be magnetic to varying degrees. [ 80 ]
Massive sulfide deposits are ore deposits that have significant stratiform ore bodies consisting mainly of sulfide minerals.Most massive sulfide ore deposits have other portions that are not massive, including stringer or feeder zones beneath the massive parts that mostly consist of crosscutting veins and veinlets of sulfides in a matrix of pervasively altered host rock and gangue.
Kidd Mine or Kidd Creek Mine is an underground base metal (copper-zinc-silver) mine 24 km (15 mi) north of Timmins, Ontario, Canada. It is owned and operated by Swiss multinational Glencore Inc. The ore deposit was discovered in 1959 by Texas Gulf Sulfur Company. Exploration drilling at the Kidd site began in November 1963.
The one-story, nearly-8,000-square-foot fortification is bulwarked by concrete walls 30 inches thick. The two exterior entrances have armored steel blast doors — one paired with a radiation ...
Sedimentary exhalative deposits (SEDEX or SedEx deposits) are zinc-lead deposits originally interpreted to have been formed by discharge of metal-bearing basinal fluids onto the seafloor resulting in the precipitation of mainly stratiform ore, often with thin laminations of sulfide minerals.
A sulfide deposit is an ore body or rock containing a great deal of sulfide minerals. Articles on this topic include: Seafloor massive sulfide deposits;
