Geology of the Ajax East and Ajax West, silica-saturated alkalic copper-gold porphyry deposits, Kamloops, South-Central British Columbia
Ajax East and Ajax West deposits are two of a number of porphyry copper-gold deposits that are hosted by the silica-saturated alkaline Iron Mask batholith, in the southern part of Quesnellia. The northwesterly trending batholith is an Early Jurassic composite intrusion emplaced in the Nicola Group, …

An evaluation of indicators of prospectivity and potential mapping of porphyry deposits in middle and southern British Columbia by a GIS study of regional geochemical and other geoscientific data.
… presents mineral potential maps for prospecting porphyry deposits at the regional scale. The study area covers certain geological units in southern and middle British Columbia (from 48°N to 56°N) that are known for hosting major porphyry deposits. Four main types of data were used in this …

Tectonic, magmatic and metallogenic evolution of the Cajamarca mining district, Northern Peru
… e.g. fault, vein and fracture arrays, at the porphyry deposits have subparallel NNW and NE-NNE trends that suggest they were directly controlled by a regionally extensive stress regime. The physiochemical conditions that prevailed during early stage hypogene mineralisation strongly influenced …

Metal- and alteration-zoning, and hydrothermal flow paths at the moderately-tilted, silica-saturated Mt. Milligan copper-gold alkalic porphyry deposit
… deposit is a tilted (~45°) Cu-Au alkalic porphyry located 155 km northwest of Prince George, B.C., Canada. It is the youngest of the BC alkalic porphyry deposits, all of which formed between 210 to 180 Ma in an extensive belt of K-enriched rocks related to the accretion of the …

Geochemical Evolution at White Island, New Zealand
… of the environment associated with formation of porphyry copper deposits. White Island has only been active for about 10 Ka and, as such, is thought to be an ideal location to study early magmatic processes associated with formation of porphyry copper deposits. In this study, the geochemistry of …

Application of platinum-group element (PGE) geochemistry to select geological problems
Porphyry deposits produce nearly 75% of the world's Cu, 95% of its Mo and 35% of its Au. These deposits are related to subduction zones, and their tectonic setting is a critical factor in determining their occurrence. However, not all porphyries give rise to economic mineralisation. Over 90% are …

Data-driven approaches towards understanding trace metal and magmatic processes in arc volcanoes, with applications to Java, Indonesia
… hosts one of the largest and most productive porphyry copper deposits in the world. To understand Java’s volcanism, I combine my data-driven petrological methods with microanalytical techniques applied to whole rock powders, individual crystals, and melt inclusions (small pockets of magma …
