| Abstract: | 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 as follows:,(1)"Maanshan style",typical ore-controlling structure in the Mangchang ore field,with veins in the upper portion and strata in the lower portion,dominated by vein-like orebodies;(2)"Tongkeng style",typical ore-controlling structure in the Dachang ore field,also with veins in the upper portion and strata in the lower portion,but dominated by layered orebodies;(3)"Jianzhupo style",typical ore-controlling structure in the Wuxu ore field,dominated by vein-like orebodies.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. |
