Mobilisation and Bioavailability of Arsenic Around Mesothermal Gold Deposits in a Semiarid Environment, Otago, New Zealand [PDF]
The Scientific World Journal, 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 ...

Mesothermal Lode Gold Deposit Central Belt Peninsular Malaysia [PDF]
, 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”.

Petrology of hydrothermal metasomatism of intra-ore dolerite dikes of mesothermal gold deposits
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 There is a necessity of working up the geology-genetic theory of hydrothermal gold deposit formation instead of the four hypotheses excepting one another: granitogene, basaltogene, metamorphogene, polygene.

Geofluids, Volume 2022, Issue 1, 2022., 2022 The Roc Blanc Pb‐Zn‐Ag‐Au vein deposit is located in the NW of Marrakech, in the Central Jebilet massif. It is spatially related to Bramram‐Tabouchennt‐Bamega (BTB) granodioritic pluton (ca. 330 Ma) metamorphism aureole. The main veins hosted in black shales are oriented N‐S to NNW‐SSE. Pb‐Zn‐Ag‐Au ore is associated with quartz, chlorite, sericite, and
