Porphyry tin deposit.
The Tashan deposit in eastern Guangdong was discovered in the 1950's, and underground mining has been in progress since the 1970's. It contains about 7280 t Sn (avg. grade: 0.64%) with orebodies mainly hosted in the granite porphyry.
Mineralization at Tashan occurs in a 1.5 km long, 100–250 m wide, and 350 m deep region. It contains over 19 NE-trending (40–50°) ore bodies, dipping 30–60° SE, with a length of 40–860 m and thickness of 0.2–13.5 m. Mineralization is characterized by quartz–silicate or quartz veins containing cassiterite and sulfides hosted by the granite porphyry and minor in Jinji Formation strata.

The Tashan deposit is hosted and genetically associated with the highly fractionated A-type granite porphyry formed at ca. 138 Ma. Its Sn metallogenic processes can be subdivided into three stages: biotite–K-feldspar–cassiterite (stage I, main Sn mineralization), quartz–cassiterite (stage II), and chlorite–sulphides (stage III).

Stage I is represented by the developing of potassium alteration as indicted by the occurrence of K-feldspar and biotite. Cassiterite is widely distributed in this stage and occurs as euhedral to anhedral grains, making it the main Sn mineralization stage at Tashan. Other minerals, such as quartz as well as minor muscovite, fluorite, chalcopyrite, pyrrhotite, and pyrite are also found in this stage. These minerals together form veinlet disseminated ores distributed in granite porphyry.

Stage II is characterized by locally developed, 0.5–50 cm thick, quartz veins, which are mainly composed of quartz + cassiterite + sulfides (e.g., pyrite, chalcopyrite, pyrrhotite, and galena) and rarely biotite and fluorite and hosted in the granite porphyry. Cassiterite is similar to those in the former stage and is mainly dispersed in ores. The ore veins in this stage commonly crosscut ore replace the ores in the former stage.

Stage III is represented by widely occurrence of low temperature altered minerals (e.g., chlorite and calcite) and sulfides (e.g., sphalerite, pyrrhotite, and pyrite). Ore veins occur as veins and veinlets and only minor cassiterite was found. Ore veins from this stage generally crosscut the quartz veins in the former stage.
