WebJan 2, 2024 · Chromitite seam formation is modeled using an infiltration metasomatic model, in which a fluid becomes progressively undersaturated in pyroxene as it rises into the hotter part of the crystal pile. As this pyroxene-undersaturated fluid moves through a noritic protolith, it dissolves the Cr-bearing orthopyroxene to produce an anorthosite. WebJan 15, 2024 · Chromium is the earth's 21 st most abundant element (about 122 ppm) and the 6 th most abundant transition metal.
