MULTI-LEVEL GEOLOGICAL MAPPING APPROACHES OF THE PLANE AREA AND APPLICATIONS: A CASE STUDY IN 1∶50000 SHEETS OF GANGKOU, TAIXIAN,ZHANGDIANGONGSHE, TAIXINGXIAN AND SHENGCITANGZHEN
摘要
Abstract
To take geological survey of 1∶50000 sheets of Gangkou,Taixian,Zhangdiangongshe,Taixingxian and Shengcitangzhen for an example,geological mapping technologies for three depth levels of shallow (0 to 4 m),Quaternary and bedrock depth have been discussed in this paper.Different combination of effective mapping methods should be selected to determine different mapping targets of different depths.Shallow deposits are mapped by the methods of groove drilling,DEM analyzing and RS (remote sensing) image interpretation.The stratigraphic framework of Quaternary deposits is established by combination of drilling and integrated geophysical logging.The bedrock geological characteristics are studied according to the regional magnetic data combined with the shallow seismic exploration method.These geological methods could obtain geological information effectively.The multi-scale three-dimensional geological models of different depth and precision are established based on a variety of geological information.The multi-level geological structure characteristics are presented by three-dimensional modeling,which enriches 1∶50000 geological mapping results.Finally,the applications of different level mapping results are discussed,leading the way of expression and application of 1 ∶ 50000 geological mapping results in plane area.关键词
