本研究地球化学数据处理范围:92°30′~100°15′E,40°00′~43°00′N,跨新疆、甘肃、内蒙古三省(区)。基础数据来源为1:20万地球化学数据库。1铜地球化学异常分布以Cb+s=26μg/g为异常下限,在全区确定了4个铜地球化学省和15个铜区域异常。Cu的浓度阶为31,37,47,67,最高含量为383μg/g(10~(-6))。总体看来,异常分布分带明显,明显的受到构造单元的控制,显示出铜的地球化学富集与古生代地壳演化的密切关系。异常与已知矿床及矿化点对应
The scope of geochemical data processing in this study ranged from 92 ° 30 ° to 100 ° 15’E and from 40 ° 00 ° to 43 ° 00’N across three provinces (autonomous regions) in Xinjiang, Gansu and Inner Mongolia. The basic data source is 1: 200000 geochemical database. 1 Distribution of copper geochemical anomalies With Cb + s = 26μg / g as the lower limit of anomaly, four copper geochemical provinces and 15 copper anomalies were identified in the whole area. The concentration of Cu is 31,37,47,67 and the highest content is 383μg / g (10 -6). In general, the distribution of anomalies is obviously zonally and obviously controlled by tectonic units, showing the close relationship between the geochemical enrichment of copper and the Paleozoic crustal evolution. Abnormalities correspond to known deposits and mineralization points
