SITUATED on the eastern margin of Kangdian axis the lead-zinc mineral belt is an important mineral occur- rence of lead-zinc in southwestern China. It is 1 200 km in length from Kangding in Sichuan Province tonortheastern Yunnan Province, and 500 km in width from west to east. There are four large deposits,fourteen middle deposits and many small deposits or mineralized spots. Famous large deposits such as Doliangzi, Tianbaoshan, Chipu and Kuangshanchang are distributed in this belt. 1 Geological setting There are many mineral-bearing strata in carbonate-hosted lead-zinc deposits of this mineral belt,such as Dengying formation (Zbdn), Longwangmiao formation (_2 l) Erdaoshui formation ( _3 e ),Daqing formation(O_2 d ), Daguan formation (S_2d ), the lower Devonian and Baizuo formation ( C_1 b).
