用剩余重力异常对玲珑大岩体几何形体的研究

USING REMNENT GRAVITY AUORMALIES TO STUDY THE GEOMORPHIC FORMS OF LING LONG MAIN GRANITE BODY

本文利用重力剩余异常计算得出的玲珑大岩体的几何形体为一南厚北薄的楔形体，其与毕郭岩体及北部的滦家河岩体在深部则是互相连接的。岩体重心并不是传统认为的以郭家店为中心，而是从曲家至崔苕附近长达５０ｋｍ以上的区域重心带，重心带厚度均在６ｋｍ以上。

Through calculating the remuant gravity anormalies the paper indicates that the geomorphic form of Linglong main granite body is Wedge-like body with thick in South and thin in North and is connected with Biguo granite body and to north Lanjiahe granite body in deep.The gravity centre is located not traditionally believed in Guojiadian Village but along a regional gvauinational bect with length up to 50km from qujia Village to near ceizhao Village. The thicknesses of the belt are all more than 6km.
