湖南邓阜仙半隐伏复式花岗岩体的二维形态研究
A study of the two-dimensional morphology of Dengfuxian semi-concealed compound granitic body in Hunan Province
摘要
Abstract
This paper describes in brief the geological background of Dengfuxian half-concealed compound granitic body.According to characteristics of density,gravity and magnetic anomaly and surface geology as well as regional geochemical composite anomaly,the au-thor holds that Dengfuxian gravity low is the reflection of Dengfuxian rock mass and its concealed part.Based on the gravity gradient zone,residual anomaly and zero line of vertical second derivative anomaly around the rock mass,the author determined the position and boundary of the semi-concealed rock mass,and chose a representative gravity profile to conduct two-dimensional morphological inver-sion.On such a basis,the author puts forward some new opinions in the aspects of the morphology,attitude,buried depth of the top and bottom as well as its contact relationship with the wall rocks,the distribution of the Batuan rock mass and its contact relationship with Hanba rock mass.关键词
