Abstract：The Lala copper deposit is located in the southwest margin of the Kangdian Axis in Sichuan Province, with the Paleoproterozoic metamorphic volcanic rocks as its ore-bearing country rocks. The ore deposit is a sedimentary-metamorphic copper deposit of volcanic eruptions. Through geological investigation, microscope identification, electron microprobe analysis and other means, the authors studied the modes of occurrence of ore fabric, the main useful components and associated elements of molybdenum, cobalt, gold, rare earth elements and platinum group elements. The useful associated elements occur mainly as independent minerals and subordinately as isomorphism. Minerals of platinum-group minerals, such as ore of bismuth-telluride-nickel-palladium and ore of telluride-palladium-nickel, were found, which shows the great comprehensive utilization value of this ore deposit. Suggestions for further utilization are also put forward in this paper. According to field characteristics of the ore deposit and fabric characteristics of the ore, the ore-forming process can be divided into sedimentary ore-forming stage of volcanic eruptions, hydrothermal metamorphism stage and supergene stage.
