The Cerro Quema Au-Cu deposit is hosted by a dacite dome complex of the Río Formation, Late Campanian-Maastrichtian volcano-sedimentary sequence Panamanian magmatic arc. Its formational age constrained at ~49 Ma field evidences, crosscutting relationships and 40Ar/39Ar geochronology (Corral et al., 2016, Corral, 2021). recent molybdenite Re-Os dates Perelló al. (2020) claim that ore spatially t...
Abstract Most known porphyry Cu deposits formed in the Phanerozoic and are exclusively associated with moderately oxidized, sulfur-rich, hydrous arc-related magmas derived from partial melting of asthenospheric mantle metasomatized by slab-derived fluids. Yet, whether similar metallogenic processes also operated Precambrian remains obscure. Here we address issue investigating origin, f O 2 , S ...
Molybdenite is a common sulfide hosting many trace elements. Trace elements in molybdenite from individual deposits have been widely used to constrain the source and conditions of ore-forming fluids. However, relationship between element composition deposit types has not well investigated large dataset. Here, simple statistics partial least squares–discriminant analysis (PLS-DA) were determine ...
Abstract Porphyry Cu ore deposits are a rare product of arc magmatism that often form spatiotemporal clusters in magmatic arcs. The petrogenetic evolution igneous rocks cover the temporal window prior to and during porphyry deposit formation may provide critical insights into processes key generating these systems. This study documents Palaeocene–Eocene Yarabamba Batholith, Southern Peru, was i...
The spectral and spatial properties of the advanced spaceborne thermal emission and reflection radiometer (ASTER) data can be used in detailed lithological and hydrothermal alteration mapping related to copper and gold mineralization, particularly the shortwave infrared radiation subsystem where hydrothermal alteration minerals have diagnostic spectral absorption features. This paper reviews th...
In order to improve our understanding of the mineral potential of northern Vancouver Island beyond the wellknown intrusion-related Cu-Au-Ag(-Mo) porphyry deposits (e.g., Hushamu, MINFILE 092L 240 and the former Island Copper mine, MINFILE 092L 158) and base and precious-metal skarns (e.g., Merry Widow, MINFILE 092L 044), we need a better understanding of the stratigraphy of the Bonanza island a...
Rock unites which are exposed in Tak-I mine area are: Taknar formation (Ordovician), Mid-late Paleozoic and younger intrusive rocks. Taknar formation consists of sericite schist, chlorite schist, chlorite-sericite schist and some meta-diabase- gabbro-diorite. Taknar Polymetal (Cu-Zn-Au-Ag-Pb) Massive sulfide deposit formed at certain horizon of Taknar formation. Three style of mineralization ar...
Porphyry Cu–Au deposits are the major global source of copper, an essential metal for green transition, and a significant gold. They occur both in thick continental thin oceanic arcs at depths between ∼1 ∼6 km above parental magma chambers situated ∼5–15 depth. Although it is believed that precipitation processes these same arcs, not clear why porphyry two environments display different Cu Au e...
