SPATIAL STRUCTURE CHARACTERISTICS OF GRAVITY HIGH ANOMALY COMBINATION IN VOLCANIC AREAS: A Case Study of Northeast Inner Mongolia

摘要: 以布格重力异常的地质成因为指导，针对区域重力异常、布格重力异常、剩余重力异常中的局部重力高异常的空间分布，结合区域地质、路线地质调查成果，从三维角度认识重力高异常组合所反映的地质体主成分相构造地质特点，探讨重力高异常的成因机制，以揭示地质体的空间成生、演化规律，为区域地质调查中局部重力异常的解释提供借鉴.

Abstract: Guided by the geologic origin of Bouguer gravity anomaly, according to the spatial distribution of local gravity high anomaly in regional gravity anomaly, Bouguer gravity anomaly and residual gravity anomaly, combined with the regional and field geological survey results, the paper analyzes the geological characteristics of principal component facies of geological bodies reflected by gravity high anomaly assemblage from three-dimensional perspective and discusses the genetic mechanism of gravity high anomaly, to reveal the spatial formation and evolution rules of geological bodies and provide reference for the interpretation of local gravity anomaly in regional geological survey.
