Geological characteristics of the Daduhe gold belt, western Sichuan, China: Implications for exploration

Open Geosciences
Geological characteristics, genetic model, and exploration implications in the Daduhe gold belt are studied. Three categories of gold deposits have been distinguished: “gold deposits in the basement (GDB),” “gold deposits in the cover layer (GDC),” and ...

Machine Learning-Based Delineation of Anomalous Gold Zones from Drillhole Geochemistry in a Sulphide-Hosted Orogenic Gold System

Geosciences
Early stage mineral exploration requires the reliable identification of anomalous gold zones from drillhole geochemistry in data-limited environments. This study applies a machine learning (ML) classification framework to detect anomalous gold zones (Au ≥

U-Pb SHRIMP and 40Ar/39Ar constraints on the timing of mineralization in the Paleoproterozoic Caxias orogenic gold deposit, São Luís cratonic fragment, Brazil

Brazilian Journal of Geology
Caxias is an orogenic gold deposit in the São Luís cratonic fragment, which is correlated with the Rhyacian terranes of the West-African Craton. The deposit postdates peak metamorphism (estimated at 2100 ± 15 Ma) and is hosted in a shear zone that cuts ...

Genesis of the Xiaotazigou gold deposit in the northern margin of the north China craton: constraints from sulfur isotopes, rare earth elements, and trace elements

Frontiers in Earth Science
The Xiaotazigou gold deposit is located in the eastern section of the Chifeng–Chaoyang gold metallogenic belt on the northern margin of the North China Craton. In this study, rare earth and trace element compositions of ores and host rocks, together with
