摘要
文章以2005年广东龙门地区1∶5万比例尺的直升机航空电磁测量数据为基础资料,结合地质、航磁、地面重力等资料,建立了该区地层单元划分的地球物理标志,并对该区的地层单元进行了划分。通过与广东龙门地区地质图进行对比,发现与该图大部分吻合较好,并增加了上覆和下伏地层的岩性信息,以及若干新的地层单元。该项成果对于今后采用航空电磁法进行地质填图具有一定的参考意义。
Based on the data of helicopter electromagnetic survey with the scale of 1 ： 50000 in Longmen, Guangdong in 2005, and combined with the geology, aero-magnetic survey, ground gravitational survey, etc. , this paper first sets up the geophysical indication for the divistion of stratigraphie units, and then divides the stratigraphic units in this area. Compared with the geological map of Longmen, Guangdong, most divisions units between them coincide well, and some information of rocks at different depths and new stratigraphic units is added to the map. This achievement will help the geological mapping by using aero-electromagnetic method for the future.
