متن کاملGeochemistry, mineralization and alteration of porphyry copper in the Grouh area, Sardouya (Kerman Province) with a view to the lack of supergene zone
The Grouh area is located about 19 km north-east of Sarduyeh city in Kerman Province. The major lithological units in this area include Eocene andesite and andesitic basalt. Oligo-Miocene intrusive units include diorite, quartz diorite and granodiorite; while pyroclastic units include tuff and breccia. The alteration in the Grouh area is remarkable due to the penetration of the intrusive masses...
متن کاملThe Bijvard epithermal gold-manganese prospect area, Northern Bardaskan, Khorasan Razavi: Evidence from geology, mineralization and geochemistry
Bijvard prospect area is located in the northern part of Central Iran zone, Sabzevar zone, about 40 km north of Bardaskan. The rock units exposed in the area include Cretaceous volcano-sedimentary rocks (andesite, basalt, graywacke and conglomerate) that syenogranite porphyry unit has intruded into them. Mineralization has structural control, with N35E trending, and has altered the andesitic r...
