Gravimetric Separation of Heavy Minerals in Sediments and Rocks

Exploratory geochemistry studies of heavy minerals, stream sediments and rock in Asbkhan region, Heris, northwest Iran

The study area is located in the south of Qushadagh mountain range, in the north of Asbkhan village, Heris township. In terms of structural geology of Iran, this area is located in the main zone of Central Iran and Alborz-Azerbaijan sub-zone. The geological units of the region are including Eocene igneous and pyroclastic rocks with combination of andesitic, trachyandesitic, basaltic, tuffic and...

Recognition of heavy minerals in Oman continental shelf sediments and their application for interpretation of sediments sourc rock is the purpose of this study. Seven core samples of sea sediment and three surface samples from tidal flat area have been examined. Heavy minerals are dense grains, wich are found not only in rocks, but also in different types of sand and sediments. Separation of he...

Elasticity of Selected Rocks and Minerals

been the subject of numerous investigations (Birch, 1960, 1961). In this study, measurement of bulk density and of compressional and rotational wave velocities of a variety of rocks and minerals affords the opportunity of calculating elastic constants and of studying anisotropy in elastic velocities. Although it was not possible to take into account the effect of confining pressure on velocitie...
