///The Nandan-Hechi metallogenic belt,consisting of Mangchang,Dachang and Wuxu ore fields,is an important tin-polymetallic metallogenic belt in South China.Based on detailed field investigations,the ore-controlling styles of this belt can be classified into 3 styles.Moreover,the geological setting and structure characteristics of different ore-controlling styles are discussed.According to these ore-controlling styles,it is suggested that some places,such as the northwestern Maanshan Pb-Zn ore deposit in the Mangchang ore field,and the east and south of the Jianzhupo Pb-Zn ore deposit in the Wuxu ore deposit,are probably the loci of concealed orebodies.
