Magmatic segregation deposits

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.
