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。 ②magnetic: TEM had low response value, high magnetic anomaly, middlehigh electrical resistivity, and low polarization value。 Ma, indicating the major iron minerogenetic period concentrated in Devonian. At the aspect of regional minerogenetic tectonic background, the tectonic location of the Qiaoxiahala ore deposit was argued according to different geologists: 1)Siberia plate→Altay continental crust part→Ertix Pz2 early exssentioned continental margin magmatic belt (Xiao Xuchang et al., 1992)。4. Bureau of Geology and Mineral Resources in Xinjiang, Wulumuqi, 830000Abstract: The Qiaoxiahala FeCuAu deposit as a typical ore deposit presents Qiaoxiahalatype mineral deposits, a group of FeCuAu deposits related to volcanism in Early Paleozoic. This paper has expounded the describing pattern, minerogenetic pattern and prospecting model of Qiaoxiahalatype mineral deposits in details.Key words: Qiaoxiahalatype, model of mineral deposits, minerogenetic series of mineral deposits, mineral deposit type1 IntroductionMinerogenetic series of mineral deposits presents a natural group of mineral deposits with genetic relationships formed at a certain geological period or a tectonic movement stage in a certain geological unit and a certain tectonic position under a certain mineralization (Chen Yuchuan et al., 2007). It is a brandnew natural classification of mineral deposits. Minerogenetic system includes five order classes of units: minerogenetic series association of mineral deposits and minerogenetic series type of mineral deposits。(6)地表找礦標(biāo)志：在喬夏哈拉東礦區(qū)和西礦區(qū)地表能見(jiàn)到磁鐵礦鐵礦(化)體露頭。喬夏哈拉銅金礦化區(qū)顯示高磁異常。之后地表磁鐵礦出露處有民采遺跡。(1)地質(zhì)條件：①構(gòu)造環(huán)境：?jiǎn)滔墓F銅金礦床處于額爾齊斯斷裂南側(cè)的額爾齊斯擠壓帶內(nèi)。喬夏哈拉黃鐵礦鉛同位素的206Pb/～；207Pb/～；208Pb/～；～，顯示正常鉛的特征(萬(wàn)博等，2006)。
