Abstract Barite deposits of the Lasbela District, Balochistan, hosted in the Ferozabad Group (FG) of Jurassic are relatively pure and have BaO value ranging from to % with minor amounts of Sr, Fe and Ca. The measured average density of the studied samples ( g/cm3) is compatible with the API13A specification. The quantity of watersoluble alkaline earth metals found is very low ...

"Feldspar" is the name of a large group of rockforming silicate minerals that make up over 50% of Earth''s crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties.
In 1996, a memorandum of understanding was signed by representatives of the Geological Survey and Kennecott Greens Creek Mining Company to initiate a cooperative applied research project focused on the Greens Creek massive sulfide deposit in southeastern Alaska. The goals of the project were consistent with the mandate of the Geological Survey Mineral Resources Program to maintain a ...

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of orebearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten
