The use of rock has had a huge impact on the cultural and technological development of the human race. Rock has been used by humans and other hominids for at least 2.5 million years. [22] Lithic technology marks some of the oldest and continuously used technologies. The mining of rock for its metal content has been one of the most important ...
Mineralogy applies principles of chemistry, geology, physics and materials science to the study of minerals. Mineralogy [n 1] is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.
Nickel E H, Nichols M C (2007) IMA/CNMNC list of mineral names compiled by Ernest H. Nickel & Monte C. Nichols supplied through the courtesy of Materials Data, Inc.: it updates the Nickel-Strunz 9 ed mineral identifiers, with this publication the mineral database had increased from less than 3,000 to over 4,000 mineral species.
The minerals are then concentrated using sluices or jigs. [citation needed] Large drills are used to sink shafts, excavate stopes, and obtain samples for analysis. Trams are used to transport miners, minerals and waste. Lifts carry miners into and out of mines, and move rock and ore out, and machinery in and out, of underground mines.
Systematic scientific studies of minerals and rocks developed in post-Renaissance Europe. [2] The modern study of mineralogy was founded on the principles of crystallography and microscopic study of rock sections with the invention of the microscope in the 17th century.
In rocks, some mineral species and groups are much more abundant than others; these are termed the rock-forming minerals. The major examples of these are quartz, the feldspars, the micas, the amphiboles, the pyroxenes, the olivines, and calcite; except for the last one, all of these minerals are silicates. [39]
Geochemistry is the science that uses the tools and principles of ... practically all rocks contain felspars or feldspathoid minerals. In the acid rocks, the common ...
The visible and near infrared (VNIR) and thermal infrared (TIR) are sensitive to intra-atomic electronic transitions and inter-atomic bond strength respectively can help mineral and rock identifications. The instrument in use is called spectroradiometer in lab and imaging spectrometer or multi-/ hyper-spectral scanner as imaging remote sensors. [3]
