As exploration is time-consuming, costly, and risky, determination of the erosion surface a metalliferous deposit before geophysical surveying drilling might be very helpful. Geochemical haloes can used to determine whether supra-ore or sub-ore thus reduce risk operations. The aim this investigation North ROK porphyry (NRPD) in northwestern British Columbia Canada using linear productivity (LP)...

The phyllic alteration in a number of circum-Pacific porphyry Cu-Au deposits is related to high-temperature saline magmatic fluids. This contradicts the widely used genetic models wherein phyllic alteration formed as the result of mixing between magmatic and meteoric fluids. At the Endeavour 26 North porphyry deposit in eastern Australia, the transition from early potassic to the main-stage phy...

The Mount Milligan deposit, centred at latitude SS”O8’ north and longitude 124”04’ west, is 100 kilometres westsouthwest of Mackenzie and 160 kilometres northwest of Prince George in central British Columbia. The deposit occurs in gently rolling topography (Plate 2-6-l) 5 kilometres due south of Mount Milligan. Access to the property is by a 93.kilometre logging road that connects with the Hart...

The fast mineral exploration system with remote sensing is a brand new exploration system of recognition, identification, analysis and prediction. It takes metallogenic materials as the detection targets, uses the spectrum measuring technique as detection means and takes the spatial and temporal sequence of mineralization and alteration information as an evaluation basis. It develops and improv...

the ali-abad porphyry copper deposit is located in the central iranian magmatic belt. as a result of subduction magmatism, oligo-miocene leucogranitoid rocks have intruded into conglomerates of lower cretaceous age. due to contact metamorphism the following mineral assemblage has occurred in the altered conglomerate: garnet (andradite-grossular) + epidote+ quartz + calcite + pyrite skarnificati...
