中文摘要:选择云南易门地区作为研究试验区, 采用微量元素主成分因子-泛克里格模型对地球化学弱信息进行增强, 建立了判识隐伏断裂或地质单元界线的地球化学标志, 对在土壤覆盖区划分不同地质单元的地球化学依据进行了初步探讨。经与地质填图结果对比, 证明该方法在实践工作中是可行的, 对指导土壤覆盖率高、地表地质工作难度较大的地区的地质工作具有重要的指导意义。 |

A Tentative Discussion on the Division of Geological Units in the Soil-covered Area: A Case Study of Yimen Area in Yunnan Province |
|
|
Abstract:With Yimen area in Yunnan Province as the study area, the authors employed the principal component factor of trace elements with Pan-Kriging model to enhance weak geochemical information, established geochemical criteria for judging and recognizing concealed faults or boundaries of geological units, and made a tentative discussion on the geochemical grounds for dividing geological units in the soil covered area. A comparison with the geological mapping shows that this method is feasible in practice. The results obtained by the authors are of important guiding significance for geological work in soil-covered areas where surface geological work is likely to meet with great difficulties. |
