mineralogyScientific study of minerals, including their physical properties, chemical composition, internal crystal structure, occurrence and distribution in nature, and origins or conditions of formation. Mineralogic studies range from description and classification of new or rare minerals to analysis of crystal structure and laboratory or industrial synthesis of mineral species. The methods employed include physical and chemical identification tests, determination of crystal symmetry and structure, optical examination, X-ray diffraction, and isotope analysis. mineralogy the branch of geology concerned with the study of minerals How to thank TFD for its existence?

Mineralogically, the ore changes with increasing depth from galena to galenafreibergite, to galena-freibergite-sphalerite-siderite, to sphalerite-freibergitegalena-siderite, to sphalerite-siderite, to siderite-pyrite-sphalerite. It's quite mineralogically diverse," says Slack of the rock's mineral content, which contains on average of about 65 per cent igneous calcite (calcium carbonate), 10 per cent apatite (rock phosphate) and some potassium-bearing species. IDPs show a variety of mineralogically distinct compositions, but until now, astronomers had never directly linked an IDP to a meteoritic source. |
