The mineralogy, structure and geological setting of the world's largest stratabound tin-polymetallic sulphide deposits of Dachang and Gejin (South China) are now presented to the international readership for the first time. In addition, reviews of the world's major types of tin deposits and models of grades and tonnages allow worldwide comparisons. The world's foremost tin metallogenic province of Southeast Asia is described in papers on Indonesia, Malaysia and Thailand. Several papers describe tin deposits outside the Asian region, notably Tasmania, Western Canada, the Iberian Peninsula, and South America.
