· 10. Schneiderhöhn Classifiion •Schneiderhöhn also considered only mineral deposits related to magmatic processes. •Four main classes are recognized depending on the nature of the orebearing fluids: intrusive and liquidmagmatic (magma), pneumatolytic (gases under high temperaturepressure conditions), hydrothermal (aqueous solutions ...
Chromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not wellrepresented in mineral collections. Chromite is isomorphous with the mineral Magnesiochromite and is easily confused with it, as they ...

· An example of a potential structualcontrolled ore shoot. Note the fold in the rock. The folded structure in the lower photo is identified as 'folded ore shoot'. The 'nose of folds (ore shoot)' may be enriched in gold, as I found at the Duncan and Carissa mines at South Pass.
· The molcajete (derived from the Náhuatl molcaxitl from molli seasoning or sauce and caxitl box) is the Mexican Spanish name for a traditional stone pestleandmortar, and is of prehistoric ancestry. Whilst perhaps not quite as ancient as the metate, it is a tool that was being used in Mesoamerica thousands of years ago. No Mexican kitchen is complete without one.

· The photo does not show segregation quartz veins, but a metamorphic rock called migmatite. Sometimes a rock is called a migmatite because of the presence of segregation quartz veins in it, but this is a misnomer: segregation quartz forms at hydrothermal conditions, while in migmatites the segregation of minerals into veinlike structures is ...
How to Recognize Hard Rock Gold Ores. September 2017 by Chris Ralph. I regularly get inquiries along the line of: "Hey, I found this rock, and I think it might be gold ore. How can I tell?" Prospectors are always on the lookout for goldbearing rocks that may be the source of any nearby placer gold.

· A new line of research, stereological reconstruction, arose from the obvious observation that an arbitrary cross section of a spherical shape is always less than its characteristic cross section (Fig. 2, above).And it follows from this that the volume fraction of the convex mineral phase in the rock and ore, equal to the fraction of its flat sections, is always .

Intrusive rocks such as this muscovite granite form from magma that solidifies beneath the Earth's surface. Over millions of years scalding hot water leaches copper and other metals out of the rocks and deposits them in veins of ore. Later, erosion exposes the rocks on the surface.
· Sedimentary rocks are formed from the erosion of older instrusive, volcanic rocks or even other sedmentary rocks. They may also be formed through biologic processes, such as coral reef formation. Mineral deposits may form in sedimentary rocks through the erosion of orebearing rocks or through the mobilization of orebearing fluids through ...
Porphyrytype mineralization takes the form of disseminated ore minerals (chiefly of copper, molybdenum and gold) occurring within large bodies of intrusive acid to intermediate igneous rock. They are a particularly important source of copper in global terms: despite the typically low grades (sometimes less than 1% Cu), such orebodies can ...
