Significance of heavy minerals

WebTools. In geology, a heavy mineral is a mineral with a density that is greater than 2.9 g/cm 3, most commonly referring to dense components of siliciclastic sediments. A heavy mineral suite is the relative percentages of heavy minerals in a stone. Heavy mineral suites are used to help determine the provenance and history of sedimentary rocks. WebGlobally, the principal thorium resources occur in a variety of REE deposits and some heavy-mineral sands (Fig. 10.3), which are mineral deposits in which the thorium minerals are accessory to other ore minerals. Significant REE deposits of all deposit types, as well as monazite-bearing deposits of heavy-mineral sands, are not only the largest ...
