通过对吉林省白山地区1∶20万地球化学元素中Au、Cu、Pb、Zn、Co、Ni等6 504个样品进行因子泛克里格模型进行定量组合求异,最终确定白山地区地球化学元素异常是多个元素组合,揭示不同成矿作用。全区共圈定出组合异常22处,组合异常具有明显的分带性,分为3个带:Ⅰ带元素组合以Co-Mn-Ti为主,显示在玄武岩覆盖下寻找Co矿的潜力很大;Ⅱ带元素组合以As-Au-Sb为主,显示该带是金矿的密集区;Ⅲ带元素组合为Cr-Ni。该带异常为与超基性岩、暗色火山岩类有关的元素聚集过程。
In this paper, 6 504 samples of Au, Cu, Pb, Zn, Co, Ni among 1: 200000 geochemical elements in Baishan area of Jilin Province were quantitatively combined and identified by factor-pan-kriging. Finally, the geochemical elements Abnormal is a combination of multiple elements, revealing different mineralization. A total of 22 anomalies of assemblages were identified in the region, and the anomaly of the anomaly has obvious zonation. There are three zones: the elemental composition of the zone I is dominated by Co-Mn-Ti, showing great potential for looking for Co ore under basaltic cover ; The composition of Ⅱ-band elements is mainly composed of As-Au-Sb, which indicates that the belt is a gold-intensive area; and the Ⅲ-element combination is Cr-Ni. The anomaly is an element aggregation process related to ultrabasic rocks and dark-colored volcanic rocks.
