This article describes the characteristics of gold–sulfide–quartz and gold–sulfide (gold–arsenic) ore occurrences in Manitanyrd region Polar Urals. Ore are confined to NE-trending shear zones have common features a geological structure. The host rocks metamorphosed volcanic volcanic–sedimentary rocks. We analyzed mineral chemical composition mineralization all studied occurrences, showing that ...

Deficiency rickets results from a deficiency of vitamin D that is responsible for deficient calcium absorption, leading to failure of bone mineralization and cartilage bone growth, especially in children. We report the case of a 9-year-old girl who shows signs of rickets. Her family history, which includes similar malformations in several family members, led us to suggest vitamin D-resistant ri...

Numerical analysis of geophysical data to uncover Precambrian belts and probably enclose mineral deposits is becoming once more communal in mining activity. The method founded on typifying zones branded comprehend looking for analogous areas. proposed work outlines a semi-automatic image processing system the structural investigation Bou Azzer inlier, which varies from preceding approaches as i...

Two texturally and mineralogically distinct types of Mississippi Valley-type mineralization are hosted by the upper Cambrian Metaline Formation in northeastern Washington. Josephine-type mineralization is iron poor and coarse grained, whereas Yellowhead-type mineralization is iron rich, fine grained, and commonly botryoidal. Josephine mineralization is found largely in the Josephine lithofacies...

this paper presents the new geochemical isotopes sr and nd, and the mineralization data for the south neyshabour volcanic rocks located in ne iran. based on the chemical classifications, the studied rocks are basaltic trachy andesite, trachy andesite, trachyte, and trachy dacite in composition. all the analyzed volcanic rocks display enrichment in light rare earth elements (lree) relative to th...

An assemblage of hydrous, Cl-bearing alteration-induced minerals is present within 150 m of footwall-style Cu–Ni–PGE sulfide mineralization hosted by the Sudbury Breccia at the Fraser Copper zone, Fraser mine, Onaping–Levack area, Ontario. The pyroxene hornfels to hornblende hornfels contact-metamorphic aureole of the Sudbury Igneous Complex (SIC) contains less than 15 modal % hydroxysilicates....
