中文摘要:东昆仑祁漫塔格构造带位于东昆仑造山带西北部，发育一系列大-中型矽卡岩矿床。哈西亚图Fe-Au矿床位于祁漫塔格构造带东部，铁、金矿产规模已达中型，仍具有较大的找矿空间。哈西亚图Fe-Au矿床具有明显的层控矽卡岩型矿床特征，矿体产在南倾的灰岩-矽卡岩地层中。矿区北部的早-中三叠世闪长岩早期被认为是潜在的致矿岩体。文章发现矿区北部存在闪长岩(（247.9±4.3）Ma)和辉长闪长岩(（241.6±2.3）Ma)2种岩体，野外观察表明矿区北部岩体与矿体之间没有明显的接触交代现象。自东向西，矿区矿种分别为铁、铜、金、锌矿化，指示矿化温度由高到低，东部为热液中心。矿区东北隐伏区钻孔中发现晚三叠世二长岩(（220.2±1.7）Ma)，该岩体具有埃达克质岩的特征(w（Yb）<1.3×10-6,w（Y）<16×10-6,La/Yb>40)，且具更高的氧逸度（ΔFMQ+0.54～+1.20），是哈西亚图矿床潜在的致矿岩体。矿区地球物理磁异常资料显示，东北隐伏区和现有矿区具有相似的磁异常值；结合区域构造分布情况，文章在矿区和东北隐伏区之间识别出1条具有左行走滑性质的断层，揭示了矿区和东北隐伏区为被该断层错断的同一成矿系统，故东北隐伏区具有巨大找矿潜力。在传统的勘查方法之外，文章选取矿区内16个钻孔开展短波红外光谱（SWIR）测试，发现金矿化段的特征吸收峰位普遍大于2207 nm，铁矿化段的特征吸收峰位普遍大于2205 nm。文章利用钻孔揭露的矿化信息建立了矿体三维模型，清晰地展现了矿区内存在深部和浅部2个含矿层，二者之间被一层片麻岩隔开，其中位于深部的第二层矿体目前还未被控制，具有良好的找矿前景。
Abstract:The Qimantagh belt is situated in the northwestern part of the East Kunlun Orogenic Belt, where a series of medium to large sized skarn deposits are well-developed. The Haxiyatu Fe-Au deposit is located in the eastern segment of the Qimantagh belt, with the scale of iron and gold mineralization having reached the medium-sized category and significant prospecting potential. The Haxiyatu Fe-Au deposit exhibits distinct characteristics of stratabound skarn-type deposits, with orebodies occurring in south-dipping limestone-skarn strata. The Early Middle Triassic diorite in the northern part of the mining area was previously considered a potential ore-forming intrusion. In this study, two types of intrusions were identified in the northern mining area: diorite（247.9±4.3 Ma） and gabbrodiorite(（241.6 ± 2.3）Ma). Field observations indicate that there is no obvious contact metasomatism between the intrusions in the northern mining area and the orebodies. From east to west, the mineral species distribution in the mining area is characterized by iron, copper, gold, and zinc mineralization sequentially, which indicates a gradual decrease in mineralization temperature and suggests that the eastern part of the mining area is the hydrothermal center. Late Triassic monzonite(（220.2±1.7）Ma) was discovered in drill holes within the concealed area in the northeastern part of the mining area. This monzonite possesses the geochemical characteristics of adakitic rocks(w（Yb）<1.3×10-6, w（Y）<16×10-6, La/Yb>40) and exhibits significantly higher oxygen fugacity（ΔFMQ+0.54～+1.20）, making it a potential ore-forming intrusion for the Haxiyatu deposit. Geophysical magne-tic anomaly data of Haxiyatu indicate that the concealed area in the northeast shares similar magnetic anomaly values with the mining area. Combined with the regional tectonic distribution, a left-lateral strike-slip fault was identified between the mining area and the northeastern concealed area in this study. This finding reveals that the mining area and the northeastern concealed area belong to the same metallogenic system displaced by the aforementioned fault, and the northeastern concealed area holds substantial prospecting potential. Beyond traditional exploration methods, 16 drill holes in the mining area were selected for short-wave infrared spectroscopy（SWIR） analysis in this study. The results show that the characteristic absorption peak positions of gold mineralization intervals are generally >2207 nm, while those of iron mineralization intervals are generally >2205 nm. Utilizing the mineralization information revealed by drill holes, a three-dimensional orebody model was established in this study. This model clearly demonstrates the presence of two ore-bearing layers（a deep layer and a shallow layer） in the mining area, which are separated by a layer of gneiss. Among them, the second（deep） layer of orebody has not yet been controlled, presenting excellent prospecting prospects.
