The Dachang tin-polymetallic deposit, which is located in the northwestern part of the Guangxi Zhuang Autonomous Region, contains great amounts of indium. But the occurrence and enrichment of indium are rather complex and not yet well understood. In this paper, the Dachang West ore belt (Tongkeng, Gaofeng) sphalerite is taken as the research object. Based on detailed field investigation and indoor microscopic observation of mineral phase, the spatial distribution law, occurrence state and relationship with main metallogenic elements of scattered elements indium were studied by means of high-precision electron probe and plasma mass spectrometry, in order to reveal its enrichment in sphalerite. The study results show that the content of scattered elements indium in the sphalerite of the Tongkeng deposit decreases with the increase of depth, while the Gaofeng deposit remains stable. Indium occurs mainly in the form of isomorphism and enters sphalerite lattice in the form of double substitution of zinc with copper, but does not exclude the possibility of indium being deposited as a sub-microinclusions. On the basis of previous studies, it is inferred that the indium-rich and copper-rich fluids produced by magma crystallization are metasomatic and enriched with the early-formed sphalerite in the late evolution of Granite Magma. The results of this study point the way to mineral processing and the search for scattered elements indium.
