Mobilisation and bioavailability of arsenic around mesothermal gold deposits in a semiarid environment, Otago, New Zealand. [PDF]

open access: goldScientificWorldJournal, 2002
Arsenopyrite (FeAsS) is the principal arsenic (As) mineral in mineralised mesothermal veins (typically 5,000 mg/kg As) in southeastern New Zealand. Groundwater in contact with arsenopyrite-bearing rocks has elevated As concentrations (up to 0.1 mg/l). The arsenopyrite decomposes slowly on oxidation in soils and historic mine workings in a cool semiarid

Mesothermal Lode Gold Deposit Central Belt Peninsular Malaysia [PDF]

open access: hybrid, 2012
Malaysia had already established itself as one of the important gold producer long before the development of the great gold-fields such as in South Africa, Australia and USSR (Chu & Singh, 1986; Becher, 1983; Santokh Singh, 1977). Prior to the Portuguese conquest of Malacca in 1511, the country was known as the “Aurea Chesonese” or “Golden Peninsular”.

A Fluid Inclusion Study of the Brookbank Deposit, Northwestern Ontario: A Transition from Mesothermal to Epithermal Gold Deposition [PDF]

open access: goldMinerals, 2018
The Brookbank and Cherbourg Zone gold deposits are located in the Beardmore–Geraldton greenstone belt of the Wabigoon Subprovince of the Archean Superior Province of the Canadian Shield. Brookbank is a shear zone deposit, whereas the Cherbourg Zone, joined by a shear zone to the Brookbank, is a fissure vein deposit, presumably formed by the same ore ...

Geochemistry of the Youngbogari deposit, Republic of Korea: An unusual mesothermal gold-silver deposit of the Youngdong area.

open access: goldGEOCHEMICAL JOURNAL, 2002
Mesothermal gold-quartz veins of the Youngbogari deposit in the Youngdong area, South Korea, are hosted in faulted shear zones in Precambrian gneiss of the Sobaegsan massif. The Youngbogari deposit shares many features with other metamorphic rock-hosted gold deposits in the area, including a massive single-stage nature of veins and a simple vein ...

Gilt by Association? Origins of Pyritic Gold Ores in the Victory Mesothermal Gold Deposit, Western Australia

open access: closedEconomic Geology, 2000
Sulfur isotope data and calculated fluid-rock reaction paths constrain the origin of pyritic gold ores in the Victory mesothermal gold deposit of Western Australia. Pyrite δ 34S values range from –4.4 to +5.1 and are negatively correlated with gold tenor in mafic host rocks, indicating a significant increase in fluid oxidation state accompanied ...

Geochemistry and genesis of mesothermal gold deposits in Korea: Base metal-rich gold mineralization of the Byungjibang mine, Hwoingsung area.

open access: bronzeJOURNAL OF MINERALOGY, PETROLOGY AND ECONOMIC GEOLOGY, 1999
Electrum (79.67-88.68 atom.%Ag)-sulfide mineralization of the Byungjibang mine in the Hwoingsung area represents the first recognized example of mesothermal gold mineralization of late Cretaceous age in South Korea, and was deposited in three stages of mineralogically simple, base metal-rich quartz±calcite veins that filled the fractures in Cretaceous ...
