Disseminated Epithermal Gold Deposits - 911 Metallurgist

Mar 26, 2018· Gold mineralization occurs near the surface most strongly disseminated within the zones of silicification, but it also is found in trace amounts in the argillic altered rocks. Mercury, antimony, and arsenic occur anomalously in and near exposed disseminated gold …

disseminated gold mineralization associated with orogenic ...

Disseminated gold, without quartz veins, occurs in some types of Klondike Schist, typically near mineralized orogenic veins. The disseminated gold and sulphide minerals (mainly pyrite) are

(PDF) Disseminated gold mineralization associated with ...

The disseminated gold occurs with fine disseminations of pyrite that are concentrated along foliation surfaces and is associated with a distinctive spotty chlorite and ankerite alteration and weak...

Jun 01, 2009· Gold mineralization was recorded in assoc iation with the banded iron formation ... Gold occurs as disseminated t iny grains within both silicates and ir on oxides . Minerals of the BIF. Ibrahim Badr

Alteration and mineralization styles of the orogenic ...

Sep 01, 2019· Orogenic disseminated gold refers to deposits where the host rock itself is mineralized (e.g., Bierlein et al., 2001; Christie and Brathwaite, 2003, Craw et al., 2006). This type of deposit was firstly found by narrow alteration zone surrounded gold-bearing quartz lode (Arehart, 1996). After several years research, it has been reported that the alteration halos can extend to as much as 150 m in width and the disseminated deposit can occur solely as an important gold …Cited by: 8

Disseminated Ore - Mining Fundamentals

Disseminated mineral deposits can be very large, with maximum dimensions measuring in the 10s of kilometers. They are formed by a number of geologic processes and, in most cases, contain very large amounts of ore. Gold, copper, molybdenum, and several other valuable metals have been discovered and mined from disseminated deposits.

Relationship Between Magmatism and Mineralization in the ...

Sedimentary rock-hosted disseminated gold mineralization occurs at Alligator Ridge and along the western margin of Mooney Basin, forming a ~40 km north-trending belt of gold deposits and prospects, the best described of which is the Vantage deposit (Ilchik, 1990). In these deposits, gold is hosted in Devonian through Mississippian

Gold Mineral Properties - Geology

Therefore, most gold found in nature is in the form of the native metal. Gold occurs in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits. The most obvious physical property of gold is its color.Chemical Classification: Native element
