摘要
The Gao’aobei tungsten-molybdenum deposit is a newly-discovered large-scale altered rock type deposit. The outcropped strata are mainly Sinian silicastone and Cambrian metamorphic rocks. Folds and faults are few in this area . The late Triassic monzonitic granites largely occurred in the eastern part of the ore district. The wall rock alterations are dominated by hornstonization, albitization, greisenization, fluoritization, tourmalinization, chloritization and sericitization, of which the albitization and greisenization are closely associated with the mineralization. The tungsten-molybdenum ore bodies are hosted in the NWW direction alteration belts. They are of large-scale, extend stably, have continuous mineralization and are of high-grade. The discovery of the Gao’aobei deposit is not only a significant guidance to ore-prospecting breakthrough of altered rock type W-Mo deposits around the boundary between Hunan Province and Jiangxi Province in the Nanling metallogenic belt, but also a new direction to study the genesis of tungsten-molybdenum deposits related to granites.
