Gold mineralization in the Um El Tuyor area, South Eastern Desert, Egypt
… that constrain the hydrothermal alteration and gold mineralization in the Um El Tuyor area, SE Egypt. In order to distinguish the characteristics and envisage the genesis of gold mineralization in the study area, insights into the geologic context, structural evolution and geochemistry of the …

Gold mineralization in the Missanabie-Renabie district of the Wawa subprovince (Missanabie, Ontario, Canada)
… responsible for the formation of hydrothermal gold deposits are often equivocal. For example, gold-bearing, shear zone-hosted laminated quartz veins in the Missanabie-Renabie gold district (Archean Wawa subprovince, Ontario, Canada) have been interpreted as both intrusion-related and …

Time-Space Relationships between Sediment-Hosted Gold Mineralization and Intrusion-Related Polymetallic Mineralization at Kinsley Mountain, NV
Carlin-type gold deposits (CTGDs) in north-central Nevada contain a large endowment of gold, making Nevada one of the world's leading gold producers. Most CTGDs occur in four distinct clusters, known as the Carlin Trend, Cortez, Getchell, and Jerritt Canyon. These four camps of CTGDs are estimated …

Fracture reactivation and gold mineralization in the epithermal environment : structural evolution of the Endeavour 42 gold deposit, New South Wales, Australia
… pit mine at the Endeavour 42 (E42) epithermal gold deposit, situated in the Junee-Narromine Volcanic Belt of the Ordovician Macquarie Arc, central New South Wales, has provided a 3D view of the structurally controlled deposit which was hitherto not available due to the paucity of outcrop in the …

Multi-stage orogenic gold mineralization of the Pine Lake greenstone belt: evidence from the Seabee Gold Operation, Trans-Hudson orogen, northern Saskatchewan
The Seabee Gold Operation, located within northern Saskatchewan, Canada, hosts the Seabee and Santoy deposits, as well as important exploration targets, including the Fisher property. These properties occupy the Pine Lake greenstone belt, hosted within the Glennie domain of the larger …

Structural analysis of the north-central Glennie Domain and controls on gold mineralization in the Santoy Gap Hanging Wall deposit, Seabee area, northern Saskatchewan
… The domain also hosts the only producing gold mine in Saskatchewan, Seabee Gold Operation, currently producing from the Santoy deposits situated along a splay of the Tabbernor fault zone. This thesis presents results of structural study at a range of scales and involves two main …

The stratigraphic and structural controls on copper-gold mineralization at Cassenha hill prospect, within the Archean to Paleoproterozoic Angolan shield, Congo craton, South Western Angola
The Cassenha Hill copper-gold prospect is situated in the Catabola area, Huambo Province, southwestern Angola. Geologically, the prospect is part of the Angolan Central Eburnean Zone (CEZ) and consists of Paleoproterozoic metasedimentary rock sequences which have been intruded by Eburnean …

Lode gold deposit characterization using evidence from stream sediments: an example from Brush Creek, Montgomery County, Virginia
… correlation between the heavy minerals and the gold. However, analysis of the relict phases intergrown with the gold grains yields important results. Placer gold grains recovered from streams draining the Brush Creek deposit, in southwestern Virginia, contain relict quartz, orthoclase, ilmenite …

CHARACTERIZING THE AURIFEROUS SYSTEM AT PORKY LAKE WITHIN THE PINE LAKE GREENSTONE BELT, NORTHERN SASKATCHEWAN, WITH A FOCUS ON PETROGRAPHY AND MINERAL CHEMISTRY
Gold mineralization occurs within the Pine Lake greenstone belt in several known and prospective deposits in northern Saskatchewan, Canada. The mineralization systematics at some of these locations within the Seabee Gold Operation, including the Porky Main and Porky West deposits, are poorly …

Die Genese der Goldlagerstätte Hira Buddini, Südindien
The Hira Buddini Gold Mine is situated in the Hutti-Maski Greenstone Belt of the Indian Dharwar Craton. Hydrothermal gold mineralization is hosted by a narrow ENE- trending steep dipping reverse shear zone at the lithological contact of metabasalt,metadacite and metagabbro. The host rocks are …

Paragenetic Evolution of the Robertson Deposit: Eocene Intrusion Related Gold Deposit in the Northern Shoshone Range, Nevada
… known as Tenabo, is an Eocene intrusion-related gold deposit 5 km north of Pipeline, which is a 20 Moz+ Carlin-type gold deposit in the northern Shoshone Range, Nevada. Carlin-type gold deposits have been the focus of many studies as they represent the second largest accumulation of gold in the …

Structural and metamorphic evolution of the Ormsby Zone and relative timing of gold mineralization: a newly defined Archean orogenic gold prospect hosted on the Discovery Property, Yellowknife greenstone belt, Slave Province, Canada
… has produced approximately 14 million ounces of gold, 13 of which came from the well explored southern half of the belt. The northern half of the belt, where the Discovery Property (1 million ounce past producer) is located, is not as well explored, but geologically very similar to the gold …

Tektono-metamorphe Kontrolle der archaischen Goldmineralisation in der New Consort Gold Mine, Barberton Grünsteingürtel, Südafrika
The New Consort Gold Mine in the Palaeo- to Mesoarchaean Barberton greenstone belt, South Africa, is one of the oldest recognized orogenic gold deposits on Earth. The gold mineralization is hosted by discrete mylonitic units, the so-called Consort Bar, which occurs at the contact between the c. …

History of the fluids associated with the Proterozoic Star Lake lode-gold deposit, northern Saskatchewan, Canada
… subparallel northeasterly-striking shear zones. Gold mineralization was fracture-controlled, and the main stage of deposition occurred during late fracturing episodes within the shear zones. The majority of the fluid inclusions trapped within the vein-quartz are of secondary origin, and are …

Structural study of the auriferous Santoy shear zone, northeastern Glennie domain, Saskatchewan
… the Santoy 7, Santoy 8/8 East, and “Santoy Gap” gold deposits. This shear zone was studied using a structural and geochronological (ID-TIMS) approach in order to decipher its complex relationship with plutonism, deformation, alteration, and gold mineralization. Surface and subsurface mapping …
