The Gandy gold-base metal deposit is located in Tertiary Torud-Chahshirin volcano-plutonic range, north of Central Iran. Various styles of gold mineralization occur throughout the range. Mineralization at Gandy occurs in close spatial relation with rhyolitic domes in a caldera setting in a series of narrow brecciated veins. Two mineralogically and spatially different argillic alterations have a...

Abstract Integrating structural control on mineralization and geochemical ore-forming processes is crucial when studying deformed ore deposits. Yet data are rarely acquired at the same scale: typically investigated from district to deposit macroscopic scales whereas described microscopic scale. The deciphering of a deformation–mineralization history valid every scale thus remains challenging. T...

The Tareek Darreh gold deposit is located 40km north of Torbat-e Jaam in the Khorassan-Razavi province, NE-Iran. The study area mainly comprises slightly metamorphosed, sedimentary rocks of Jurassic age including alternation of shale, siltstone, and sandstone. These rocks have been intruded by plutonic rocks such as gabbro-norite, diorite, quartz-diorite, and rhyodacite. The ore bodes are expos...

Currently, uranium production occupies a decisive place in the world energy industry. In Kazakhstan, to meet demand for uranium, hydrogenous deposits with technologically and economically favorable natural indicators are being developed, including large Semizbai deposit. The deposit by genesis belongs hydrothermal-hydrogenous polygenic type terrigenous sandy-clayey deposits. As result of geolog...

the trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. a very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. these elements may be concentrated in non-magnetic and magnetic part of calcrete. based on the current research, mineralogica...

Abstract Dongping is the largest Au-Te vein deposit (~120 t Au) in North China craton, but its age, origin, and setting remain unsolved. Here, we integrate paragenesis, geochemistry, situ U-Pb geochronology of garnet to constrain timing possible origin deposit. Gold mineralization at hosted Shuiquangou alkaline complex (ca. 401–390 Ma) dominated by quartz-sulfide veins with minor ores adjacent ...

The Shuangwang gold deposit, with more than 70 tons of Au, is located in the Fengxian-Taibai ore concentration area Qinling Orogen central China, hosted a Northwest-trending breccia belt. Fragments body are cemented by ankerite, albite, quartz, calcite, and pyrite. Four metallogenic stages identified mineral paragenesis: quartz-albite, ankerite-pyrite-albite, pyrite-quartz-calcite, fluorite-anh...
