Chuquicamata, in northern Chile, is the world’s greatest copper orebody. It was controlled, from the initial intrusions (probably at 36–33 Ma) through mineralization (last major hydrothermal event at 31 Ma) to postmineral brecciation and offset, by the West fault system. East porphyry, West porphyry, Banco porphyry, and Fine Texture porphyry make up the Chuqui Porphyry Complex. East porphyry, the dominant host rock, has a coarse, hypidiomorphic-granular texture. Intrusive contacts between most… Expand
Chuquicamata , the world ’ s greatest copper orebody
Chuquicamata, in northern Chile, is the world’s greatest orebody. It was mainly controlled by initial intrusions (probably at 36 to 33 Ma) through mineralization (last major hydrothermal event at 31Expand
Timing and formation of porphyry Cu–Mo mineralization in the Chuquicamata district, northern Chile: new constraints from the Toki cluster
The recently discovered Toki cluster, which includes the Toki, Quetena, Genoveva, Miranda, and Opache porphyry Cu–Mo prospects, is located 15 km south–southwest of the Chuquicamata–Radomiro TomicExpand
Reported supergene sphalerite rims at the Chuquicamata porphyry deposit (northern Chile) revisited: Evidence for a hypogene origin
Previous studies attributed a supergene origin to sphalerite rimming copper minerals occurring in Chuquicamata in a mineral assemblage including typically chalcocite-digenite (Cu1.85S1.12 andExpand
GEOCHEMISTRY OF IGNEOUS ROCKS ASSOCIATED WITH THE MMH PORPHYRY COPPER DEPOSIT, CHUQUICAMATA DISTRICT, CHILE
The MMH deposit is located 7 km to the south of the Chuquicamata mine within the Chuquicamata District in northern Chile, in the Domeyko Cordillera. The two deposits are located on opposite sides ofExpand

Mineralogy and mineral geochemistry of the Tuwu porphyry Cu deposit, Eastern Tianshan, NW China: implication for the ore-forming condition and Cu mineralization
The Tuwu deposit is one of the largest porphyry copper deposits in Eastern Tianshan, NW China. The widespread hydrothermal alteration is associated with porphyries and their wall-rocks in theExpand
Geochronology of the Xiaodonggou Porphyry Mo Deposit in Northern Margin of North China Craton
The Xiaodonggou porphyry Mo deposit is located in the Mesozoic calc-alkaline Xiaodonggou granitoid within a Palaeozoic fold zone of northern China. The mineralization mainly occurred in an area ofExpand
Evidence of Ediacaran glaciation in southernmost Brazil through magmatic to meteoric fluid circulation in the porphyry–epithermal Au–Cu deposits of Lavras do Sul
Abstract The Lavras do Sul Au–Cu mining district, southern Brazil, hosts an Ediacaran plutonic–volcanic association with hydrothermal alteration. This association is interpreted as a ca . 600–580 MaExpand
Porphyry deposits and oxidized magmas
Abstract Porphyry deposits supply most of the world's Cu and Mo resources. Over 90% of the porphyry deposits are found at convergent margins, especially above active subduction zones, with much fewerExpand
