X-ray transmission (XRT) and computed tomography (CT) was used on five samples from the Niaz porphyry Cu–Mo deposit in Iran, representing different alteration zones. Analysis of three-dimensional CT data revealed structural information groups elements with low, medium high attenuation, which were assigned to minerals previously determined by scanning electron microscopy. Thus, mineralization ca...

The origin of hypogene alteration and mineralization features in the Escondida porphyry Cu deposit resulted from intense overprinting related to three main hydrothermal stages. beginning each stage is recorded by deposition bright quartz crystals on vein walls that precipitated high-temperature fluids. In deepest zones deposit, earliest started with exsolution intermediate-density fluids, which...

The Casino Cu–Au–Mo deposit is one of the largest and highest-grade porphyries its kind in Canada, residing an unglaciated region west-central Yukon. A batch 22 stream water samples eight groundwater were collected proximal to for purpose identifying most diagnostic trace element isotopic pathfinders associated with hydrothermal mineralization, as well establishing natural hydrogeochemical base...

Demingding is a promising porphyry Mo-dominated deposit recently discovered in the eastern Gangdese metallogenic belt Tibet, China. We present zircon U-Pb-Lu-Hf isotopic studies, as well geochemical data of late monzogranites and prior rhyolites from to uncover their origin geodynamic mechanism. Zircon U–Pb dating yielded precise crystallization ages 17.3 ± 0.6 Ma (MSWD = 2.5) 186.5 3.0 2.0) fo...

Detection of deep and hidden mineralization using the surface geochemical data is a challenging subject in the mineral exploration. In this work, a novel scenario based on the spectrum–area fractal analysis (SAFA) and the principal component analysis (PCA) has been applied to distinguish and delineate the blind and deep Mo anomaly in the Dalli Cu–Au porphyry mineralization area. The Dalli miner...
