Abstract: The stratigraphical, lithological and structural controls of hydrothermal Sb, Ba, Cu, F, Pb-Zn and Sn-W deposits of northern Thailand (viz. north of lat. 17°30‘N) are statistically determined and evaluated. Most deposits appear to be strata-bound. Strata-binding mineralization of various ore deposits occurred notably in the Ordovician Hod Limestone, Silurian-Devonian Don Chai Formation, Permo-Triassic Volcanic Group and Triassic Hong Hoi Formation. The Jurassic red beds of Khorat Group are limited to copper mineralization in particular. Similarly, hydrothermal tin-tungsten deposits are invariably related to granitic rocks of Triassic and younger ages. The result of investigation has also showed that within any square grid area equivalent to the 1:50,000 topographic map sheet, the ore deposits, by large, exhibit spatial relationship to the set of lineaments whose total length is the longest.
