introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...

The paper presents the results of comprehensive isotope geochemical (Re-Os, Pb and ?34S) study sulfide mineralization Morozkinskoye deposit. ore zones deposit are localized in syenite massif Mount Rudnaya, which is located within Central Aldan region (southern Yakutia). Gold represented by vein-disseminated or vein type manifested acidic low-temperature metasomatites – beresites (Qz-Ser-Ank-Py)...

The Alta Floresta Gold Province (PAAF) is abundant in gold deposits and, located the state of Mato Grosso, Brazil, an ideal place to study geoelectric signature mineralization. Auriferous mineralization occurs along shear zones quartz veins and disseminated granites this region. Ores are associated with oxides sulfides, mainly pyrites. To identify primary or continuities mineralized zones, data...

Tourmaline-bearing quartz veins and replacement deposits, commonly copperand gold-bearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them. Mines and prospects that exploit the tourmaline-bearing deposits are found in a zone approximately 70 miles long and 50 miles w...
