Study on the ore-controlling structure of Yanglin'ao tungsten deposit and the mineralization prediction, Hunan province

Yanglin'ao tungsten deposit is a typical mesothermal to hyperthermal filling-metasomatism postmagmatic deposit. It is featured with the structure-controlling distribution of ore-body and mineralization; while veinlet-type ore-bodies are particularly situated at the hanging wall of F24(No.24 of Fault Fracture), and the mineralization is especially concentrated below and above the unconformable surface between Proterozoic Banxi slate group and Middle DevonianYanglin'ao sandstone formation. Geological characteristics, structure forms and its formation mechanisms of ore-controlling structure were studied in this paper and a special tectonic-controlled model was initially set up. Furthermore the author also made mineralization prospecting prediction based on structure characteristics.
