| 摘 要： | 对新疆—甘肃—内蒙古衔接区的1∶20万地球化学数据研究结果表明，该区Cu地球化学异常主要与基性、超基性岩和斑岩体有关，成矿元素组合为Co-Zn-Cr-Ni-Cu；W地球化学异常主要与中酸性岩有关，成矿元素组合为W-Sn-Bi。区内主要铜、钨矿床和新发现的矿床（点）均有相应元素区域异常显示，表明地球化学异常在本区具有重要指示意义。在全区确定了4个Cu地球化学省、5个W地球化学省、15个Cu区域异常和17个W区域异常，其中上马崖—铜山Cu地球化学省、黄山—梧桐窝子—葫芦北Cu地球化学异常带、土屋—赤湖Cu区域异常、大狐狸山Cu地球化学省、鹰嘴红山W地球化学省、古堡泉—柳园W地球化学省、英姿山W区域异常具有重要的找矿意义。

| Abstract: | According to the 1:200000 geochemical data of the Xinjiang-Gansu-Inner Mongolia border area, the copper geochemical anomalies are mainly related to the mafic-ultramafic rocks and the porphyry bodies, and the ore-forming elements are of Co-Zn-Cr-Ni-Cu combination; the tungsten geochemical anomalies are mainly related to the intermediate-acid rocks, and the ore-forming elements are of W-Sn-Bi combination. Most of the copper deposits and tungsten deposits in this area have the corresponding element anomalies, suggesting that the geochemical anomalies have important prospecting significance. The authors identified 4 copper geochemical provinces, 5 tungsten geochemical provinces, 15 copper regional anomalies and 17 tungsten regional anomalies, among which Shangmaya-Tongshan copper geochemical province, Huangshan-Wutongwozi-Hulubei copper geochemical anomaly belt, Tuwu-Chihu copper regional anomaly, Dahulishan copper geochemical province, Yingzuihongshan tungsten geochemical province, Gubaoquan-Liuyuan tungsten geochemical province and Yingzishan tungsten regional anomaly have important ore-prospecting significance. |
