| 英文摘要 | All the indium-rich deposits with indium contents in ores more than 100x10(-6) seems to be of cassiterite-sulfide deposits or sn-bearing pb-zn deposits, e.g., in the dachang sn deposit in guangxi, the dulong sn-zn deposit in yunnan, and the meng'entaolegai ag-pb-zn deposit in inner mongolia, the indium contents in ores range from 98x10(-6) to 236x 10(-6) and show a good positive correlation with contents of zinc and tin, and their correlation coefficients are 0.8781 and 0.7430, respectively. the indium contents from such sn-poor deposits as the fozichong pb-zn deposit in guangxi and the huanren pb-zn deposit in liaoning are generally lower than 10x10(-6), i.e., whether tin is present or not in a deposit implies the enrichment extent of indium in ores. whether the in enrichment itself in the ore -forming fluids or the ore-forming conditions has actually caused the enrichment/depletion of indium in the deposits? after studying the fluid inclusions in quartz crystallized at the main stage of mineralization of several in-rich and in-poor deposits in china, this paper analyzed the contents and studied the variation trend of in, sn, ph and zn in the ore-forming fluids. the results show that the contents of lead and zinc in the ore-forming fluids of in-rich and -poor deposits are at the same level, and the lead contents range from 22x 10(-6) to 81x10(-6) and zinc from 164x10(-6) to 309x10(-6), while the contents of indium and tin in the ore-forming fluids of in-rich deposits are far higher than those of in-poor deposits, with a difference of 1-2 orders of magnitude. indium and tin contents in ore-forming fluid of in-rich deposits are 1.9x10(-6)-4.1x10(-6) and 7x 10-6 -55x10(-6), and there is a very good positive correlation between the two elements, with a correlation coefficient of 0.9552. indium and tin contents in ore-forming fluid of in-poor deposits are 0.03x 10(-6)-0.09x10(-6) and 0.4x10(-6)-2.0x 10(-6), respectively, and there is no apparent correlation between them. this indicates, on one hand, that in-rich oreforming fluids are the material basis for the formation of in-rich deposits, and, on the other hand, tin probably played a very important role in the transport and enrichment of indium. |
