  • Magmatic Segregation Mining Fundamentals

    Some of the commonly formed mineral deposits formed due to magmatic segregation are iron, granite, aluminum, diamond, chromite, and platinum. The different temperatures and basicity zones that prevail in magma cause the concentration of the ore, thereby resulting in the segregation of various minerals.Ore deposits produced by magmatic segregation, with,2020-10-13 · In recent years the theory of the origin of ore deposits by magmatic segregation has taken strong hold upon students of economic geology. The segregation theory was a bold departure from the earlier views that all ore bodies were the result of concentration by circulat­ ing meteoric waters, and it has furnished the most satisfactory explan­

    Abstract. 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 relationships, from ore textures and from the results of experimental petrology that the ores have segregated during the crystallization of a magma.Magmatic hydrothermal deposits SpringerLink,Abstract. In the previous chapter we have described some of the mineral deposits that have formed by magmatic activity, often by segregation within the magma chamber itself. In this chapter we turn our attention to other magmatic activity which results in important mineral deposits. These are not ores that have segregated during crystallization of

The mineral system approach considers the origin of these deposits in the framework of lithospheric-scale processes from the time-honoured perspective of source, fluids, transport and traps.

    The magmatic segregation and formation of pegmatites leaves the residual magma very fluid and it contains gases of great chemical activity. These gases penetrate the adjacent country rock and by their reaction with the latter form mineral deposits Such deposits are known as pneumatolydc ore deposits. Examples are cassiterite deposits.Magmatic Ore Deposits in Layered ,2012-2-7 · Layered, ultramafic to mafic intrusions are uncommon in the geologic record, but host magmatic ore deposits containing most of the world’s economic concentrations of platinum-group elements (PGE) (figs. 1 and 2). These deposits are mined primarily for their platinum, palladium, and rhodium contents (table 1).
