esteghlal fireclay mine, northern abadeh, with dominant composition of kaolinite and pyrophyllite, and annual production of over a million tons, is one of the largest sedimentary deposits in iran. linear spectral unmixing (lsu) and mixture tuned matched filtering (mtmf) processes were applied on the vnir + swir dataset of aster for identifying the frequency fraction and distribution of clay min...

A method of clay mineral sample preparation for electron microprobe analysis has been developed in which a film of clay plus 10-12 wt. % colloidal graphite is deposited on a porous ceramic disc using a specially designed suction device. Correction procedures are used to obtain quantitative elemental analyses representing the average chemical composition of the prepared sample. A statistical tec...

We aimed to study the composition and availability of various vitamin preparations in the Indian market, data about which was collected from an annual Drug Compendium. The preparations were assessed for total number, different formulations, constituents and amount of each constituent present in the formulation. A large number of vitamin supplements are available in the Indian market. It include...

this paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from mighan playa aquifer. cluster analysis classified samples into four clusters(a, b, c and d) according to their dominant chemical composition: cluster a (dominant comp...

We report isotopic and chemical compositions of unusual tridymite–hercynite xenoliths in middle Miocene Niutoushan tholeiites from the southeast coastal area of China. These xenoliths are characterized by positive cerium (Ce) anomalies and extremely high Al2O3 (32–34 wt.%) and total iron oxide (20–22%). They have Sr/Sr of 0.7050–0.7058, eNd(0) values of + 3.2 to + 4.2, Pb/Pb ratios of 18.8–19.1...

Although multivitamins, multiminerals, and similar terms (eg, multis or multiples) are commonly used, they have no standard scientific, regulatory, or marketplace definitions. Thus, multivitamins-multiminerals refers to products with widely varied compositions and characteristics. Multivitamin-multimineral composition databases use label values as surrogates for analyzed values. However, actual...
