【正文】 地質大隊又在外圍普查，同年，物探隊進行電、磁測，否定礦床價值，認為主要異常由超基性巖引起。近年來，其規(guī)模有所擴大，截止2002年底，鐵礦石總資源儲量為462萬噸，銅31200噸，金1051千克。喬夏哈拉－老山口金銅成礦帶位于額爾齊斯異常帶和烏倫古河斷裂異常帶之間的航磁異常區(qū)，其磁場走向以北西向為主，呈現條帶狀正負相間的異常區(qū)。m左右；而在南部的背景磁場上，激電則顯示出低阻高極化特征，其中極化率大于10%，視電阻率小于100Ω②礦區(qū)：喬夏哈拉礦床東礦區(qū)II號礦體：一方面與海底火山成礦作用有關的異常有些相似，如Co、Ni、Cr的異常主要分布于礦體下方，另一方面又顯示熱液成礦作用的特點，如異常范圍寬，異常分帶明顯，As、Sb異常則主要分布于礦體下方等?，F有的礦床成礦體系中，還沒有喬夏哈拉式鐵銅金礦的確切位置，但根據該礦床的地質特征和其他礦床的對比，與索爾庫都克式銅鉬礦較為相似，可暫時地將喬夏哈拉式鐵銅金礦歸入與晚古生代構造－巖漿作用有關的鐵、銅、鎳礦床成礦系列，與華力西早期次火山－火山巖建造有關的鐵銅金礦床成礦亞系列中。喬夏哈拉式鐵銅金礦在準噶爾北緣向東南具有進一步找礦的潛力。 minerogenetic subseries of mineral deposits。massive and disseminated Cubearing magnetite ore174。 3) ZaisangNorth Junggar fold system→Fuyun tectonic formation belt→Ertix subbelt (Chen Yuchuan et al., 1995)。 ③alteration in wall rocks: epidotization occurred closely to Fe orebodies and widely spreaded, carbonation was closely related to CuAu, and silication guided for Au (Ni Liang, 2004).(2) History criteria for prospecting:①prospecting relic: the Qiaoxiahala FeCuAu deposit was found by Team 622 in Geological Bureau in 1955, and checked by Team 713 in 1958. In 1959, the Altay geological team finished the peripheral reconnaissance survey, and the geophysical team denied its economic value after electric and magnetic survey. Later it was confirmed as a smallscale deposit by the Altay geological team after initial exploration. There were magnetite open pit relic by locals on the surface。 ②in the mining area: taking orebody in the eastern mining sector as an example, it was similar to the marine volcanism anomaly such as Co, Ni, and Cr occurring beneath the orebody, meanwhile it also showed the similarity to hydrothermal mineralization with wide anomaly area, clear anomaly zoning and As and Sb anomaly beneath the orebody.(5) Remote sensing information criteria: until now, there is no remote sensing information about the Qiaoxiahala area.(6) Surface criteria for prospecting: there occurred magnetite outcrops in the eastern and western mining sectors in Qiaoxiahala.3 Prospecting significanceBased on the Palaeozoic minerogenetic region classification, the Qiaoxiahala FeCuAu deposit in Xinjiang located in the PaleoAsian minerogenetic domain→Junggar minerogenetic province→Ni, Cu, Fe, Mo, Au, bentonite, coal minerogenetic belt of North Junggar (Tang Zhongli et al., 2005). In the present minerogenetic system of mineral deposits, there is no precise position for the Qiaoxiahala FeCuAu deposit, but according to its now geological features and pared to the Suoerkuduke CuMo deposi, it can be put in the Late Palaeozoic tectonicmagmatism related Fe, Cu and Ni minerogenetic series and further the Variscan early subvolcanicvolcanic formation related Fe, Cu and Au minerogenetic subseries.In the Palaeozoic large scale mineralizion process, the Qiaoxiahala FeCuAu deposit closely correlated to the marine volcanicmagmatism or seafloor volcanicexhalation sedimentary mineralization. It’s potential to prospect Qiaoxiahalatype FeCuAu deposits in the basic volcanic rock series in the arc belt of the Variscan tectonic active zone.
