The potassium silicate (K-silicate) alteration zone is the main ore contributor in porphyry copper deposits worldwide. Knowledge of element behaviors and mineralization processes essential for an improved understanding mineralization, but they are still not well understood. In this study, we reacted synthetic Cl-rich fluids, containing K, Na, Cu, Mo, Zn, etc., with andesite a complex experiment...

the study area is a part of cenozoic magmatic belt of central iran, which is located in the west of yazd porovince. contact metamorphism and skarn occurred in conglomerate part of sngestan formation. the oligocene intrusion bodies of ali-abad-darreh zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setti...

This paper focuses on the relationships between the geological model and exploration techniques for porphyry Cu ± Au deposits, with reference to the discovery record and exploration practices over the past fifteen years. The porphyry model is built on a long record of study dating back to the 1960s which has been gradually refined to encompass differences and complexities in mineralization and ...

The Poplar copper-molybdenum porphyry deposit, 50 kilometres south-southwest of Houston, is centred near 54 degrees 01 minute north and 126 degrees 50 minutes west. The property is accessible from Houston via 80 kilometres of forest access roads along the Morice River, Owen Lake, Tahtsa Reach, and Poplar Lake. The deposit is situated on the northeast shore of Tagetochlain (Poplar) Lake in an ar...

Primary tin deposits usually contain little or no copper due to the distinct geochemistry of Sn and Cu. However, examples copper-rich in many provinces around world are also well known. The genesis remains controversial. Maodeng Sn-Cu polymetallic, a typical Cu-rich deposit southern Great Xing’an Range (SGXR) Northeast China, offers an excellent opportunity reveal coupled copper-tin deposits. o...

In this paper, we used 3D modeling and nonlinear methods (fractal, multifractal, and probabilistic neural networks (PNN)) for regional mineral potential mapping and quantitative assessment for porphyry and skarn-type Mo deposits and hydrothermal vein-type Pb–Zn–Ag deposits in the Luanchuan region, China. A 3D geological model was constructed from various geological maps, cross sections, borehol...

Fluorite is a widespread mineral in porphyry and hydrothermal vein Mo-polymetallic deposits. Here, fluorite utilised as probe to trace the fluid source reveal evolution process Chalukou giant Mo (Pb–Zn) deposit, Northeast China, which characterised early later vein-style Zn–Pb mineralisation. A detailed rare earth element (REE) Sr–Nd isotope study of combined with Sr isotopes sphalerite conduct...
