Trace metals in pyrite and marcasite from the Agua Rica porphyry-high sulfidation epithermal deposit, Catamarca, Argentina: Textural features and metal zoning at the porphyry to epithermal transition
(Elsevier, 2015-04)
Agua Rica is a world-class Cu (Mo–Au) deposit located in Catamarca, Argentina, in which the porphyry and high
sulfidation epithermal stages are juxtaposed due to the telescoping of the mineralizing system. Pyrite is the ...
The Marianas-San Marcos vein system: characteristics of a shallow low sulfidation epithermal Au–Ag deposit in the Cerro Negro district, Deseado Massif, Patagonia, Argentina
(2016)
The Cerro Negro district, within the Argentinian Deseado Massif province, has become one of the most significant recent epithermal discoveries, with estimated reserves plus resources of ∼6.7 Moz Au equivalent. The Marianas-San ...
Mineralogical, petrographic and fluid inclusion evidence for the link between boiling and epithermal Ag-Au mineralization in the La Luz area, Guanajuato Mining District, Mexico
(2017)
Theoretical, experimental and observation data provide strong evidence that boiling is the dominant depositional mechanism in many low to intermediate sulfidation epithermal precious metals deposits. Textural and petrographic ...

Silver-rich chalcopyrite from the active Cerro Pabellon geothermal system, northern Chile
(MDPI, 2020)
Active subaerial geothermal systems are regarded as modern analogues of low- to
intermediate-sulfidation epithermal Au–Ag deposits, where minor amounts of Cu are mostly present
as chalcopyrite. Although trace element ...
Vein carbonates in the low sulfidation epithermal Au-Ag District of El Peñón, II Región, Chile: environment of formation and exploration implications

Sulfide Composition and Isotopic Signature of the Altar Cu-Au Deposit, Argentina: constraints on the Evolution of the Porphyry-Epithermal System
(Mineralogical Assoc Canada, 2013-12)
Sulfides and sulfosalts from the porphyry, transitional, and epithermal high sulfidation stages of the Altar Cu-(Au) deposit (San Juan, Argentina) were investigated by electron microprobe, laser ablation-inductively coupled ...
