A study of regional geological setting and ore-control factors for the Xiasai Ag-Pb-Zn deposit indicates that NW-trending structures act as conduits for ore fluids and orebodies are controlled by a NNw-trending fault system, while ore shoot s are confined equidistantly to secondary structures associated with the NNW-trending fault system.

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.
