Abstract The Wulong deposit is a large tonnage deposit (>80 t of Au), characterized by quartz vein style of gold mineralization in the Liaodong Peninsula, China. The auriferous quartz veins are mainly hosted by Late Jurassic gneissic two-mica granite (165–157 Ma) and Early Cretaceous granodiorite (129 Ma) and are structurally controlled by NNE- and NW-trending faults. Previous attempts to date the gold mineralization yielded ambiguous results (135–112 Ma). Here we report the first in-situ and di...

The Baiyun gold deposit in the Liaodong gold province, NE, North China Craton (NCC), is a lode gold deposit hosted within the Paleoproterozoic metamorphic rocks. Disseminated and vein-hosted gold mineralization occurs along NWW-trending interlayer faults and NE-trending normal faults. Crosscutting relationships and mineral assemblages indicate hydrothermal process of the gold deposit can be divided into three stages, characterized by pyrite–quartz (stage 1), quartz–pyrite–chalcopyrite (stage 2),...

Abstract The newly discovered Dasuji Mo deposit is located on the northern margin of the North China Craton, and the Mo mineralization is related to Triassic granite porphyry and quartz porphyry. Alteration associated with the deposit includes silicification, sericitization, chloritization, K-feldspathization, kaolinitization, carbonatization, and fluoritization. The silicification and sericitization (phyllic alteration) are closely related to the Mo mineralization. Based on mineral assemblages ...

Abstract The Dasuji porphyry Mo deposit is located at the northern margin of North China Craton. Mo mineralization occurs mainly within the intrusions of alkali feldspar granite, granite porphyry, and quartz porphyry, which yield weighted mean 206Pb/238U ages (2σ) of 227.6 ± 1.5, 225.7 ± 1.5, and 224.3 ± 1.8 Ma, respectively. These ages are indistinguishable to the molybdenite Re Os isochron age of 223.9 ± 1.5 Ma (2σ). The Dasuji granites show the petrological, mineralogical, geochemical, and ge...

Abstract The Wulong vein-type gold deposit, located along the northeastern margin of the North China Craton (NCC), contains > 80 tonnes of gold at an average grade of 5.35 g/t. A total of 380 auriferous quartz veins are hosted in Late Jurassic gneissic two-mica granite and Early Cretaceous granodiorite. A paragenetic sequence, representing three hydrothermal stages, has been identified: (1) quartz ± pyrite; (2) quartz-polymetallic sulfide; and (3) quartz-calcite ± pyrite. Petrography, fluid incl...
