Alteration mapping with short wavelength infrared (SWIR) spectroscopy on Xiaokelehe porphyry Cu-Mo deposit in the Great Xing’an Range, NE China: Metallogenic and exploration implications

The newly discovered Xiaokelehe porphyry Cu-Mo deposit (PCD) is situated in northern part of the Great Xing’an metallogenic belt, northeastern China. The syn-mineralization granodiorite porphyry was intruded by multiple phases of post-ore barren monzonite, diorite porphyry and granite porphyry, leading to complex and overprinting hydrothermal alteration patterns. This paper present new data on the alteration mineralogy, vein paragenesis, sulfide...
