Genesis and geodynamic background of the ore-bearing granodiotite porphyry of the Jilongshan copper-gold deposit in Jiurui district, Hubei Province

地质科技通报, 2021
Jilongshan copper-gold deposit is located in the Jiurui metallogenic district in the middle and lower Yangtze River metallogenic belt. Cu-Au mineralization of Jilongshan deposit is closely related to granodiotite porphyry. The petrogenesis of the rock is

Mineralization of the Tuwu Porphyry Cu Deposit in Eastern Tianshan, NW China: Insights From In Situ Trace Elements of Chlorite and Pyrite

Frontiers in Earth Science, 2021
The Tuwu porphyry copper deposit is located on the Dananhu-Haerlik island arc in eastern Tianshan, NW China. Based on geology, petrology, and in situ trace element studies of pyrite and chlorite, we redefined the characteristics of hydrothermal fluids ...

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 ...

Geochronology and Structure of the Lupa Goldfield, Tanzania [PDF]

, 2012
Gold occurrences in the Lupa goldfield, SW Tanzania, are typical of the orogenic Au deposit type. Auriferous quartz veins and mylonitic shear zones cross cut Archean granitoids (ca.

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.

Magmatic controls on porphyry copper deposit formation and machine learning approaches for mineral exploration

, 2022
Porphyry copper deposits are a rare manifestation of arc magmatism, occurring in restricted spatiotemporal windows within magmatic arcs. Many of the largest deposits are related to the optimal alignment of tectono-magmatic processes, and this magmatic ...

Geochemical Characteristics and Their Geological Significance of Zircon and Apatite From the Wunugetushan Porphyry Cu–Mo Deposit, Inner Mongolia, NE China

Acta Geologica Sinica - English Edition, EarlyView.
The key factors making the monzogranitic porphyry fertile for mineralization, including its high Cl, S, and H2O contents, high oxidation state, significant fluid exsolution, and multiple recharges of deep‐seated mafic magma, were all critical for the formation of the Wunugetushan porphyry Cu‐Mo deposit. ABSTRACT The Wunugetushan (Wushan) porphyry Cu–Mo
