英文摘要The palaeoenvironment of the magnetic anomaly area in the northward Lishi, Yimen was a low depression relative to its surrounding in Proterozoic, when the subaqueous alkaline-carbonatitic volcanoes erupted. The ore-bearing layers of Yinmin Formation are consist of (sub) volcanic rocks, pyroclastic sedimentary rocks and hydrothermal rocks including clayey-nontronite rock, ferruginous rock, ferruginous sillcalite, ferruginous ruffite, carbonate rock, muddy dolomite, sillcacous dolomite et al. The rocks consisted of carbonate mineral fragments or the carbonatic rocks with sodium silicate mass are caibonatitic volcanic rocks. Nb/Ta, Zr/TiO2, Nb/Y, Zr/Hf, U/Th ratios of HFSEs, and (La,/Nd)n, (Sm/Nd)n, (La/Yb) n ratios of chorndrite-abnormalied REEs of the rocks and ores, and Co/Ni, sulfur isotopic ratios of sulfide reveal that the hydrothermal rocks is derived from alkaline-carbonatitic volcanic rocks, as well as the hydrothermal metasomatism took all important role in the mineralization. The mineralization in the hydrothermal rocks includes iron as well as copper, zinc, cobalt and silver. If compared the mineralization rocks with the typical hydrothermal ore deposit, Kuroko deposits in Japan, the network mineralized subvolcanoic rock, blocky lavas and breccia near by Lishucun are similar to the mineralized dacite dome and breccia in the eruption central. The ferruginous ruffle and ferruginous sillcalite with high BaO and gypsum occuring in same horizontal on the margin of the magnetic anomaly are corresponded to the barite and gypsum sediment in the low depression of Kuroko deposit. The main ore-bodies of Kuroko is just setting on the space between eruption opening and barite and gypsum depression, and northward Lishi magnetic anomaly just appear in this kind space. Apparently, the main body of mineralization in this area is absolutely not the small iron mine oil the margin of magnetic anomaly. A large copper-bearing iron ore deposit is most likely lying under the deep of magnetic anomaly space between the eruption central and gypsum and barite sediment.
