摘　　要：地球化学元素序结构分析是本团队研制的一套用于地球化学数据信息挖掘与地质分析的新技术方法。本文利用西准噶尔地区1∶20万化探数据,从地球化学元素序结构特征的角度,分析了该区的成矿地球化学背景、主要成矿元素异常分布及异常地质特征等,并对其找矿潜力作出评价。分析认为,西准噶尔地区主要矿床类型应为中低温热液矿床,区内Au、Ag、As-Sb-Hg、Mo-W-Bi和U-Be等元素或元素组合异常表现较为强烈,具有较好的找矿潜力。Geochemical element sequence structure analysis is a set of new technical methods developed by our team for geochemical data information mining and geological analysis.Based on the 1∶200000 geochemical data of the West Junggar area,this paper analyzes the metallogenic geochemical background,the abnormal distribution of the main ore-forming elements and the anomalous geological characteristics of the area from the perspective of geochemical element sequence structure characteristics,and evaluates its prospecting potential.The analysis shows that the main ore deposit type in the western Junggar area should be medium-low temperature hydrothermal deposit,and the anomaly of elements or element combinations such as Au,Ag,As-Sb-Hg,Mo-W-Bi and U in the area is relatively strong,which has good prospecting potential.
