Mineralization styles: veins and stockworks
Geological ages: Middle Cretaceous - Late Cretaceous (mineralization)
Coincident features: host pluton (veins and swarms of veinlets in northwest-trending 20 x 10 km pluton and in adjacent rocks); Coincident feature name: Cochahuasi Pluton
Host rocks: (1) intrusive; gabbro-diorite suite (monzo-diorite phase intruded by quartz-diorite phase); Magma series/sedimentary package/metamorphic group: calc-alkaline; Depositional setting: continental; Metamorphic grade: amphibolite
Host rock stratigraphy:Cochahuasi Pluton
Related igneous rocks: (1) intrusive; kimberlite-lamproite suite (swarms of lamprophyric dykes); Magma series: alkaline; Depositional setting: continental
(2) intrusive; granite suite (Post-tectonic felsic intrusion); Initials: Tiabaya Pluton of Coastal Batholith; Magma series: calc-alkaline; Depositional setting: continental
Metallogenic signatures: Cu
Fe
Au
Co
Mineralogy: (alteration): clinopyroxene, garnet, epidote, hornblende
(gangue): quartz, calcite, chlorite, biotite
(vein mineralization): chalcopyrite, pyrite, magnetite, bornite, sphalerite, galena, pyrrhotite, cobaltite, molybdenite, ilmenite, arsenopyrite, marcasite, melnicovite, gold
Qualified comments: (Applies to: discovery and development) Mined by local miners informally; reserves plus historic production in the order of some hundreds of thousands of tonnes averaging 1.5% Cu, with Au and Ag by-products; upper oxidized levels are richer.
