Revisiting the Pangjiahe Au Deposit, West Qinling Orogen, Central China: New In Situ Sericite and Apatite Geochronology, Fe-S Isotope Constraints, and Implications for Regional Metallogeny

Geosciences
The Pangjiahe Au deposit is the largest gold deposit in the Fengxian district of the West Qinling Orogen (WQO), Central China. However, the timing of gold mineralisation and its relationship to the regional metallogenic evolution of the WQO remain poorly

LA-ICP-MS Zircon U-Pb Dating and Geochemistry of Late Cretaceous Quartz Diorite in the Nuri Cu-Mo-W Deposit, South Tibet

Yankuang ceshi, 2015
The Nuri deposit is located at the south margin of the Gangdese metallogenic belt in Tibet. Its mineralization age revealed by Re-Os dating of molybdenite is 23 Ma, which is consistent with that of the Mingze and Chengba deposits.

AGE CONSTRAINTS AND METALLOGENIC PREDICTION OF GOLD DEPOSITS IN THE AKZHAL-BOKO-ASHALIN ORE ZONE (ALTAI ACCRETION-COLLISION SYSTEM)

Геодинамика и тектонофизика, 2021
We present new age constraints for igneous rocks and ore-metasomatic formations of the gold deposits in the Akzhal-Boko-Ashalin ore zone. In terms of their ore formation, these deposits correspond mainly to the orogenic type, which generally reflects ...

The Age and Origin of the Ruwai Polymetallic Skarn Deposit, Indonesia: Evidence of Cretaceous Mineralization in the Central Borneo Metallogenic Belt

Economic Geology, 2023
Abstract The Ruwai skarn deposit is the largest polymetallic skarn deposit in Borneo and is located in the Schwaner Mountains. The skarns and massive orebodies are hosted in marble of the Jurassic Ketapang Complex, which was intruded by Cretaceous Sukadana granitoids.

Fission-track ages of the metallogenic epoch of the Ikuno-Akenobe province in Japan.

The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1976
The igneous rock specimens taken from Ikuno-Akenobe province in Japan were dated by the fission-track technique. Ages of pre-ore dikes, ranging from 72 to 65 my, are younger than ages of Ariga granite and Yakuno metamophic rocks in this province, which are 75 and 115 my, respectively. Being obvious from the ages of post-ore dikes, ranging from 55 to 51

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.
