ABSTRACT_ The study area is located near Kanzan village, about 89km south-west of Loikaw City, Kayah State. The Mergui Group is widely distributed around the study area. In this unit, the prominent rock is sandstone and phyllite. Muscovite Granite intrudes the metasediments of the Mergui Group. The major Shan Scarp Fault, N-S trending longitudinal fault, runs in the western part of the study area, In the study area, metasedimentary rocks of Mergui Group and granite are well exposed. The metasedimentary rocks ard sandstone, siltstone and phyllite. Sandstone is fine-to medium-grained and granular texture. It is composed of quartz, orthoclase and opaque minerals. Silstone is fine-grained and composed of quartz, feldspar, mica and opaque minerals.Pyhllite is fine-grained and foliated. Granite is medium-to coarse-grained hypidiomorphic granular texture. It is mainly composed of quartz, orthoclase, plagioclase and muscovite. The common types of alteration associated with Sn mineralization in Kanzan area are greisenization, silicification, sericitization and kaolinization. The mineralization style of the Kanzan deposit is designated as vein type deposit which is hosted by the muscovite granite and metasedimentary rocks. The nature of distribution of the ore minerals in Kanzan Sn mineralization is represented by the quartz veins which contains cassiterite, pyrite ,chalcopyrite, arsenopyrite and sphalerite. Cassiterite, arsenopyrite and pyrite are early formed minerals in the vein system and late stage of the vein in represented by the chalcopyrite and sphalerite. Tin abundances range from 250ppm to 18.99% and tungsten content is from 620 ppm to 1.60% Tin is positively correlated with tungsten and copper. However, tin is negatively correlated with arsenic and rubidium. According to the mineralizations style, ore microscopic study and geochemical data, Sn mineralization of Kanzan area is associated to the granite related hydrothermal mineral system.
