Abstract

The paper deals with the geological and metallogenic characteristics of a group of tin deposits which are controlled essentially by metamorphism of the Lantang Group of Late Triassic-Early Jurassic sandstone and shale along the Lianhuashan fracture zone. The characteristics of spatial distribution and mineral association of the tin deposits suggest that their formation is closely related to fracturing and metamorphism in the fracture zone. The syngenetic sandstone ellipsoids in some ore deposits are rich in metallic elements, such as Sn, Pb, Zn and Cu, while the oolites are rich in Sn. This indicates that both the ore-forming and the rock-forming elements must have been deposited from the sea water. The oxygen and sulphur isotopes tend to show that the major ore-forming elements and fluids were not of a mantle source.
