基于欧拉反褶积方法计算辽宁地区重力变化场源特征

Determine the Field Source Characteristics of Gravity Variation in Liaoning Based on the Eulerdeconvolution Technique

以2012-2018年辽宁地区的流动重力观测资料为基础,结合实际地下地质体构造特征构建理论模型,应用欧拉反褶积法对重力变化场源深度及空间分布特征进行反演和解释。结果表明:在辽宁西部辽蒙交界和海城-岫岩断裂带附近场源位置集中,地下介质活动增强;欧拉反褶积方法适用于对流动重力观测资料的重力场反演及以场至源的定量研究应用。

In this paper,combining with the actual subsurface features of geological construct theoretical model,we employ the Euler deconvolution method to inverse field source parameters using the mobile gravity dataset from 2012 to 2018 in Liaoning.According to the inversion results of the measured flow gravity data,the field source locations are concentrated near the Liaomeng junction and the Haicheng-Xiyan fault zone in western Liaoning,and the underground medium activity is enhanced.The research in this paper shows that the Euler deconvolution method is suitable for the gravity field inversion of flow gravity observation data and the field-source quantitative research application.
