Caraga Region likewise occupies the northern and central part of the Eastern Mindanao Gold District, one of the principal gold belts of the country. The province is traditionally known for its productive epithermal to mesothermal gold ± silver deposits even during the pre-WWII times and has been a prime producer of the royal metal during the Annual budget: Personal Services-P million .

The Axi low-sulfidation (LS) epithermal deposit in northwestern China is the result of geological controls on hydrothermal fluid flow through strike-slip faults. Such controls occur commonly in LS epithermal deposits worldwide, but unfortunately, these have not been quantitatively analyzed to determine their spatial relationships with gold distribution and further guide mineral : Xiancheng Mao, Wei Zhang, Zhankun Liu, Jia Ren, Richard C.

Many examples are for a study area in the Aroroy district in the Philippines. Geologically-constrained mineral potential mapping for this area was already the topic of the author's Ph.D. thesis at Delft University of Technology in the Netherlands. This district contains 13 known epithermal gold deposits. Mount Diwata, also locally unofficially nicknamed Diwalwal, is a remote 1,metre (4, ft) high range of volcanic mountain and biodiversity area in Davao Region on eastern part of Mindanao island of Philippines. Rich in gold and copper ores and mines, it is spread across the 3 municipalities: (a) Monkayo in the province of Compostela Valley; as well as (b) Cateel and (c) Country: Philippines.

[A H G Mitchell; T M Leach]. Epithermal gold deposits have size, geometry, and grade variations that can be broadly organized around some genetic classes and, therefore, influence the exploration approach or philosophy.
Nearly 80 years ago, Waldemar Lindgren defined the epithermal environment as being shallow in depth, typically hosting deposits of Au, Ag, and base metals. Lindgren () showed that despite sharing common gangue mineral assemblages (e.g., quartz, carbonate, adularia, clays, fluorite, barite, pyrite), metal inventories of deposits were wide-ranging, with varying proportions of gold, silver, and base metals, including mercury, antimony, tellurium, and selenium.
Nine subclasses of epithermal deposits were thus grouped. Find many great new & used options and get the best deals for Academic Press: Epithermal Gold in the Philippines: Island Arc Metallogenesis, Geothermal Systems and Geology by T.

The geochemical behavior of gold in hydrothermal systems. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system.
Gold mostly occurs as AuCl − 2 in a system with temperature higher than °C (Gammons and Williams-Jones, ), and with decreasing temperature being the Cited by: developed for subsets of gold deposits such as those considered to be epithermal (Heald et al., ), intrusion-related (Sillitoe, ), bulk-mineable (Bonham, ) or epigenetic Archean (Gebre-Mariam et al., ).

Introduction. The term “epithermal deposits” was first defined by Lindgren () in a genetic classification scheme for hydrothermal ore deposits, although similar concepts were described by Lindgren ().This type of deposit is an important source of precious metals (e.g., gold and silver) and base metals (Simmons et al., ).Epithermal deposits are generally considered Cited by: 9.
Nevertheless, following a review of relevant exploration and scientific breakthroughs at the time, including the discovery of the Zijinshan high‐sulfidation Au–Cu deposits in southeastern China (Zhang et al., ) and the proven link between world‐class porphyry and epithermal deposits at Far Southeast and Lepanto in the Philippines Cited by: 1.
The Navilawa caldera is the remnant of a shoshonitic volcano on Viti Levu, Fiji, and sits adjacent to the low-sulfidation Tuvatu epithermal Au–Te deposit. The caldera occurs along the Viti Levu lineament, approximately 50 km SW of the Tavua caldera, which hosts the giant low-sulfidation Emperor epithermal Au–Te deposit.
Both calderas host alkaline rocks of nearly identical age Author: Nathan A. Forsythe, Paul G. Spry, Michael L. Thompson. OceanaGold Enters Into $ Million Gold Prepayment Agreement. 24 February OceanaGold Reports Growing High-Grade Resources at WKP in New Zealand.
