Mineral Exploration for Epithermal Gold in Northern Patagonia, Argentina

2009
Abstract Over the last decade, a new exploration frontier has opened up in Patagonia, Argentina, for gold mineralization. Important deposits, such as Cerro Vanguardia and Esquel, were discovered during this period. Despite these discoveries, basic geologic information for the vast Patagonia territory is still markedly scarce for ...

Epithermal environments and styles of mineralization: Variations and their causes, and guidelines for exploration

Journal of Geochemical Exploration, 1990
Abstract Epithermal precious- and base-metal deposits are diverse, reflecting the different tectonic, igneous and structural settings in which they occur, the complexities of their local setting, and the many processes involved in their formation. Most epithermal deposits form at shallow crustal levels where abrupt changes in physical and chemical ...

Epithermal Gold Mineralization and Modern Analogues, Kyushu, Japan

2001
Abstract The late Cenozoic volcanic activity in Kyushu is characterized by large-scale volcano-tectonic depressions. The sites of these depressions together with associated volcanism and gold mineralization migrated southeastward in northern Kyushu and eastward in southern Kyushu.

EPITHERMAL MINERALIZATION POTENTIAL OF THE VOLCANICS IN SOUTH EAST HAVRAN (BALIKESiR)

1993
The Hallaçlar formation of Upper Oligocene-Lower Miocene age is the oldest unit of the area. The volcanics of this formation are affected by widespread hydrothermal alteration. The Dedetepe formation, of Lower Miocene age, unconformably overlies the Hallaçlar formation and is characterized by andesitic lavas, tuffs and aglomerates which are not ...

Geology and mineralization characteristics of epithermal gold, suwan prospect, changwat Phitsanulok

2023
The Suwan prospect is located about 6 km northwest of the Chatree gold mine in Phitsanulok province, central Thailand. Gold-silver mineralization occurs as veins and stockworks hosted in volcaniclastic and volcanogenic-sedimentary rocks of Late Permian- Early Triassic age which is classified as a low sulfidation epithermal deposit base on ...

Epithermal Gold Mineralization, Wenatchee and Liberty Districts, Central Washington

1994
Abstract This road log uses mileposts (MP) as a reference unless otherwise stated. The mileposts are green, numbered in white, and placed on the right side of the road on small metal poles. The times refer to the viewing direction: 12:00, straight ahead; 3:00, to right; etc. Geologic data are from Livingston (1963), Taboret al. (1982,
