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...

introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...

The Bodaibo gold-bearing district in the Lena gold province of Siberia is one largest and oldest placer provinces world. Approximately 1650 tons has been extracted from region. Precise studies on source these unique deposits are lacking still controversial. Native four different locations was gathered to investigate its morphology, chemical signatures, structure inclusions. Some data primary be...

The area under investigation is the Bau gold mining district in the State of Sarawak, East Malaysia, on the island of Borneo. It has tropical climate with limited bedrock exposures and the other constraints imposed in the environment. Bau is a gold field with Carlin style gold deposits. Geological analyses coupled with remote sensing data were used to detect structure elements and hydrothermall...

This report presents three new potassium-argon isotopic age determinations of minerals associated with epithermal alteration from the Toodoggone district, north-central British Columbia. The Toodoggone area has received extensive exploration attention over the past 10 years. In addition to a former goldsilver producer (Baker mine), the district contains a major new gold-silver mine in developme...
