摘要
以区域地质资料和物性资料为依据,对黑龙江省虎林市幅重磁场特征进行了综合分析。根据航磁ΔT异常以及布格异常平面等值线展布特点,对该区的杂乱磁场区、线性磁场区和平稳磁场区进行了相关的地质解释,描述了30条断裂构造带及其重力场特征;结合重力异常和航磁异常等综合资料,按结晶基底起伏形态,将虎林盆地划分为4个隆起、3个凹陷共7个构造单元。
A comprehensive analysis is made on the characteristics of gravity and magnetic anomaly on map-area of Hulin City in Heilongjiang Province according to the geological and geophysical data. Based on the feature of plan contour of aero-magnetic(ΔT)and gravity anomalies,the relative geological interpretation was given on stray,linear and reposeful magnetic field. 30 faulted structure zones and their characteristics were described. By the study of synthetic data of aero-magnetic and gravity anomalies and the shape of crystallization base,the Hulin Basin was marked four uplifts and three depressions,i.e. seven structural units.
