Abstract: Abstract：The Xitian tin polymetallic deposit in Hunan is another major discovery after the significant breakthrough in finding the Qitianling tin deposit during tin prospecting in the Nanling belt in recent years. The Xitian tin polymetallic deposit consists of several types of deposit which encircle the Xitian granite complex and have clear genetic relation to the granite complex. With the Xitian granite complex as the center outward, multiple metallic minerals such as tin and tungsten occurring within an area of ~18 (north-south) by ~10 km (east-west) form mineralization zoning of complex
