On The Source Of Orogenic Gold Geology Geoscienceworld

Gold has historically been a key strategic commodity, and the study of gold deposit formation has long been investigated. Debate on the genesis of so-called orogenic gold deposits gt75 of gold recovered through history Phillips, 2013, continues largely because it is difficult to reliably identify the source of gold.In this issue of Geology, Gaboury.

Jun 01, 20200183321. Introduction. Gold Au mineralization is relatively common within Archean greenstone belts and has previously been linked to the onset of orogenesis in the early Earth Bierlein et al., 2006, Frimmel, 2008.The Late Archean was an especially productive period dominated by orogenic Au formation related to transcrustal shear zones in metamorphosed terranes Goldfarb et al., 2001.

Gold Deposits Their Geology Geochemistry And Genesis

The course will provide a comprehensive overview of all aspects of the geology of gold ores in both arc environments and metamorphic terranes. Aspects of the geology, geochemistry, mineralogy, alteration, structure, tectonics, and exploration approaches will be covered for the main gold deposit types of interest to explorationists.

The Geology And Genesis Of The Coffee Gold Deposit In West

The Coffee gold deposit, located in the Dawson Range, west-central Yukon, Canada, is an example of structurally-controlled, gold-only mineralization with a global resource of 4 Moz gold. Establishing the controls on ore distribution enhances exploration potential, and provides implications for the tectonic and metallogenic evolution of the northern Cordillera, and global gold deposit models ...

The Genesis Of Gold Mineralisation Hosted By Orogenic

Gold mineralisation hosted by low grade metamorphic facies, often in proximity to syn- to post-orogenic intrusives, and located within collisional orogenic belts, is commonly referred to as orogenic e.g. Goldfarb et al., 2005 Groves et al., 2003.

The Haimur gold deposit was supposed to be derived from metamorphic fluids created by dehydration and decarbonation of ophiolitic m233lange assemblages and volcano-sedimentary rocks, in which the gold was transported as AuHS 2 complexes and precipitated in reduced environment.
