KUSHK ZINC-LEAD DEPOSIT A TYPICAL BLACK-SHALE-HOSTED DEPOSIT IN YAZD STATE, IRAN

Kushk zinc- lead deposit is located about 167 km east of the city of Yazd, Iran. The geographical location of the mine is 31°, 40' N and 55", 40' E. Different rock types including volcanics and subvolcanics (rhyolites, rhyodacites, dacites, and rhyolitic tuffs) and sedimentary rocks (shale, limestones and dolomites) crop out in the area. Mineralization of the deposit occurs in black shale o...

MODELLING THE As-Au ASSOCIATION IN HYDROTHERMAL GOLD MINERALIZATION: EXAMPLE OF ZARSHURAN DEPOSIT, NW IRAN

Investigation of mineralization and fluid inclusions of the Lapeh-Zanak copper deposit, Central Alborz zone, Iran

The Lapeh-Zanak copper deposit is located about 15 km east of Tehran, in the southern part of the Central Alborz Zone. The rock units exposed in this area include a sequence of volcanic and pyroclastic rocks (basalt, andesite, trachy-andesite and dacitic and vitric tuff) belonging to the Fajan Formation with the Paleocene-Lower Eocene age, which are cut by subvolcanic igneous masses with a comp...

Epithermal Gold and Base Metal Mineralization at Gandy Deposit, North of Central Iran and the Role of Rhyolitic Intrusions

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...
