barika gold (and silver) rich massive sulfide deposit is located 18 km east of sardasht, north western part of sanandaj-sirjan metamorphic zone. rock units outcropped in this area are cretaceous metamorphosed volcano-sedimentary rocks in green schist facies, and include association of meta-andesite, meta-tuffite, phyllite and slate rocks, where the meta-andesitic unit (kmv1) is host rock to the...

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...

Mesozoic orogenic gold deposits in the Jiaojia goldfield, Eastern China show features of regular mineralization spatial distribution and have long been captivated attention geologists. This study integrates 3D modeling, model space analysis, association rule analysis to extract relationship between structural deformation mineralization. The Apriori algorithm with constraints is used quantify fa...

Mineralization along continental suture zones is facilitated through the frequent presence of pathways from fertile mantle source regions to crustal repositories. Due their inherent rheological weakness, these are often concealed, which hinders surface-based observations. Here, we use zircon U-Pb and sericite 40Ar/39Ar dating, whole-rock geochemical data, investigate crystallization mineralizat...

The Dalradian Supergroup of Britain and Ireland is mineralised by gold-tellurium vein deposits. The host succession includes carbonaceous, pyritic shales (pelites) which were a source of trace elements, including gold and tellurium. LA-ICP-MS mapping of pyrite crystals shows that late stages are enriched in gold, tellurium and lead, representing concentration of these elements during metamorphi...

in this study, the reliability of the primary gold mineralization exploration using multispectral etm+ imagery was investigated in lahroud region, northwest iran, which was conducted by integration of alteration and structural indicators. co-occurrence of the clay minerals and iron oxides is an important criterion in gold deposit exploration; therefore, their alteration zones were mapped using ...
