Orogenic Gold Mineralization in the Qolqoleh Deposit, Northwestern Iran
Resource Geology, 2007AbstractThe Qolqoleh gold deposit is located in the northwestern part of the Sanandai‐Sirjan Zone, northwest of Iran. Gold mineralization in the Qolqoleh deposit is almost entirely confined to a series of steeply dipping ductile–brittle shear zones generated during Late Cretaceous–Tertiary continental collision between the Afro‐Arabian and the Iranian ...

Gold-bearing volcanogenic massive sulfides and orogenic-gold deposits in the Nubian Shield
South African Journal of Geology, 2017The Nubian Shield is a large region of juvenile Neoproterozoic rocks that, together with its counterpart in the Arabian Shield, is part of a major accretionary orogen. It originated as late Tonian-Cryogenian island arcs on the site of the Mozambique Ocean formed by breakup of Rodinia.

Gold mobility in Archean metasedimentary belts: Implications for orogenic gold deposits
GeologyThe southern Superior Province (Canada) comprises large metasedimentary belts, such as the Pontiac and Quetico subprovinces, adjacent to Au-endowed greenstone belts. The Pontiac sedimentary rocks have been proposed as a source of Au for the highly endowed southern Abitibi greenstone belt.

Experimental Metalloid Mobilisation from a New Zealand Orogenic Gold Deposit
Mine Water and the Environment, 2015Elevated dissolved antimony (Sb) and arsenic (As) are common environmental issues around orogenic gold mines. The metalloids occur principally in stibnite (Sb2S3) and arsenopyrite (FeAsS), and are typically accompanied by pyrite (FeS2). Samples of arsenopyrite-rich (≈2.5 wt% As) and stibnite-rich (≈10 wt% Sb) ore were collected from the Globe-Progress ...

Orogenic Gold-Ore Deposits of Taimyr–Severnaya Zemlya Province, Russia
Geology of Ore DepositsThe paper presents geological and genetic typification of gold orogenic mineral deposits of Taimyr-Severnaya Zemlya associated with accretionary processes in the Precambrian and collisional ones in the Late Paleozoic. Gold-bearing mineral associations of gold-quartz and gold-sulfide-quartz deposits of accretionary formations of the Precambrian Shrenk ...
