摘　　要：The new type of copper deposits concerned with in this paper are vein copperdeposits found in the Lanping-Simao Rift Basin, Yunnan, China. As is indicated by H,O, C, S, Pb and Sr isotopes, water and mineralisers in the ore-forming fluids were derivedfrom heated meteoric waer and mantle, respectively. The metallic elements (Cu, Ag, Pb,Zn, As, Sb, Fe, REE, etc.) are characterised by a mised source from the crust and themantle.The new type of copper deposits concerned with in this paper are vein copperdeposits found in the Lanping-Simao Rift Basin, Yunnan, China.
