Abstract: The Wang Phar tungsten deposits are located 32 km west-southwest by road from Hatyai, Southern Thailand. The oldest rocks occurring in and around Wang Phar consist of a suite of metamorphosed sedimentaries of Palaeozoic age. These rocks have been intruded by an elongated north-south trending granite body of Cretaceous age. The emplacement of this granite body has resulted in the formation of hydrothermal vein systems which were concentrated in the granite cusps and impounded beneath the invaded rocks.
The vein systems at Wang Phar consist of a series of near-parallel, steep, westerly dipping and north-south striking quartz-muscovite veins with economic quantities of wolframite. Altogether there are five different localities within the Wang Phar area where significant vein developments are exposed on the surface. They are Kuen Mai Phai, Kuen Leng, Khog Yang, Klong Kung Lang and Klong Kung (or Ban Kam Chad).
