In order to determine mineralogy of rock and soil samples, reflectance and emittance spectroscopy in the near-infra red and short-wave infra-red is used extensively and found to be inexpensive. Hyper spectral remote sensing satellite data are found to be prospective to deliver in depth physico-chemistry like mineralogy, chemistry, morphology of the earth’s surface. Therefore hyper spectral data...

As well as fibre size, fibre chemistry is a determinant of toxicity of mineral fibres. On these grounds, a few years ago, the asbestos industry in Québec developed a process to modify the surface chemistry of chrysotile asbestos by fixing phosphorous atoms. The pleuropulmonary fibrogenicity and carcinogenicity of the native and surface treated chrysotile, called chrysophosphate, were tested. Bo...

Application of mineral chemistry to mineralization and alteration evaluation in Zn-Pb Angouran deposit, Zanjan

Our group has devoted to the application of Nuclear Magnetic Resonance (NMR) spectroscopy and Nuclear Magnetic Resonance Imaging (MRI) to basic science and clinical problems of bone mineral and matrix, and to the diseases associated with bone. NMR spectroscopy provides an analysis of the ionic composition and structure of the mineral crystals and matrix, i.e., the properties of bone as a materi...

This paper is an initial report on the mineral chemistry of four metamorphosed stratabound mineral deposits which are located within or adjacent to the Shuswap Complex. These are commonly referred t” as Cottonbelt, CK, Goldstream and Big I.edge deposits. Rock specimens were selected from those collected by Trygve H6y of the British Columbia Geological Survey Branch. The particular specimens cho...
