Geology and mineralization of the Tiegelongnan supergiant porphyry-epithermal Cu (Au, Ag) deposit (10 Mt) in western Tibet, China: A review

China Geology, 2022
The Tiegelongnan Cu (Au, Ag) deposit in central Tibet contains more than 10 Mt of copper ranking 29th in the world. It is characterized by typical porphyry-epithermal alteration and mineralization.

Porphyry copper formation driven by water-fluxed crustal melting during flat-slab subduction

Nature Geoscience
The prevailing view of the formation of porphyry copper deposits along convergent plate boundaries involves deep crustal differentiation of metal-bearing juvenile magmas derived from the mantle wedge above a subduction zone.

MobileMT for porphyry exploration - model studies and field examples

, 2021
Resistivity methods are an important part of the arsenal of geophysical techniques for the exploration of porphyry-style mineralization. One of the geophysical techniques that could be used to detect the porphyry targets, or its attributes is MobileMT ...

Spatial Overlay Analysis of Geochemical Singularity Index α-Value of Porphyry Cu Deposit in Gangdese Metallogenic Belt, Tibet, Western China

Applied Sciences, 2023
The statistical modeling with ILR-RPCA-back CLR has two problems when dealing with the closure effect of geochemical data. Firstly, after performing isometric logratio (ilr) transformation, robust principal component analysis (RPCA) is employed for ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

Geological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.
