Mineral Prospectivity Prediction in the Mayoumu Area, Tibet, Based on Multi-Source Exploration Information and Ensemble Learning Models

Remote Sensing
Plateau–orogenic belts host a substantial share of global gold resources, yet quantitative prospectivity mapping is challenged by complex mineralization and strongly heterogeneous, multi-scale datasets.

Mayum: an orogenic gold deposit in Tibet, China

Ore Geology Reviews, 2009
Abstract Located in western Tibet, China, the Mayum orogenic gold deposit was discovered in 2002 with estimated resources of > 80 tonnes gold. The gold mineralization is hosted by Neoproterozoic–Cambrian schists, and is controlled by nearly parallel E–W trending bedding-concordant fracture zones.
