第四系科学钻探及地层对比方法探讨

Discussion on Quaternary Scienrific Drilling and Stratigraphic Correlation Method

摘要:

随着社会经济发展的需要，地方经济可持续发展中部分环境、资源问题的基础——第四纪地质变得日益重要，第四系钻探作为第四系覆盖区填图的重要工作手段，钻探质量及编录资料的质量直接影响着第四系区域填图成果的表达。该文结合1∶5万辛安庄等五幅区调项目实践经验，对第四系科学钻探的工作流程进行了总结，并对第四纪钻孔多重地层划分与区域对比方法进行了初步的探讨。

Abstract:

Accompanying with the demand of social and economic development, Quaternary geology is becoming increasingly important, for which is a basis for sustainable development of local economy. Quaternary scientific drilling is an important means on geological mapping which covered by Quaternary sediments. The quality of geological drilling and geological logging determines the expression of geological survey of Quaternary covering region. In this paper, Quaternary scientific drilling workflow has been made, and multiple stratigraphic division and regional stratigraphic correlation of Quaternary sediments have been studied.
