WebAbstract. Some ore deposits have such an intimate association with igneous rocks that a common heritage can be inferred. In many cases it can be confirmed by a study of field … WebThe principal styles of mineral deposit which have formed by magmatic segregation are listed in Table 2.1. It is evident that nickel, copper, chromium, vanadium, titanium and the platinum group elements (PGEs) are the major elements produced from this class of deposit. In addition cobalt and gold may be significant by-product elements.

WebNov 1, 2024 · Magmatic deposits form directly from a melt by magmatic segregation, either by direct crystallization or by exsolution of an immiscible liquid. These deposits are genetically related to their host rocks, and thus mineralization age is the same as or close to the age of the host rocks. Webmagmatic-segregation deposit Concentration of particular minerals in different parts of a magma chamber during consolidation, by gravity settling, filter pressing, flow, fractional crystallization, liquid immiscibility, or gas transference; for example, the accumulation of heavy minerals such as chromite and magnetite by gravity settling.
