摘要
通过对大兴安岭浅覆盖区1∶20万小二沟幅区域化探特征元素Fe、Mg、Si、K、Sb、Hg、U等地球化学背景场分布规律的研究,对浅覆盖区地质体界线、断裂、隐伏岩体等基础地质问题进行了有益的探讨。经野外验证,在该区应用区域化探特征元素研究基础地质问题是有效的。而且对今后在浅覆盖区开展区域地质填图和提高地质填图质量、速度都将发挥重要作用。
Based on a study of the regularity governing the distribution of geochemical background fields of such regional characteristic elements as Fe,Mg,Si,K,Sb,Hg and U in 1∶200 000 Xiaoergou sheet of Da Hinggan Ling shallowly-covered region, the authors have made a useful discussion on such basic geological problems as boundaries of geological bodies, faults and concealed rock bodies. Field inspection shows that the application of regional geochemical characteristic elements to the study of basic geological problems is effective and seems likely to play an important role in conducting regional geological mapping and improving as well as accelerating geological mapping.
