日照-连云港地区重磁异常特征及其构造意义
|
摘要
航空重力、磁力测量是解决海陆过渡区地球物理资料不连续问题的有效途径,所获取的数据为进一步认识苏鲁造山带西段断裂展布、大地构造属性等基础地质问题提供了科学依据.基于最新高精度航空重磁数据,编制了日照-连云港地区1∶25万重力、磁力异常图,结合区域地质资料,分析重、磁异常特征,在日照-连云港地区圈定了郯庐断裂带、桑墟-连云港断裂、东海-赣榆断裂、五莲-桃园断裂等基底断裂构造.研究认为苏鲁造山带南部边界为桑墟-连云港断裂(连黄断裂),以该断裂为界,北侧基底为华北板块组成部分,断裂南侧为下扬子板块基底;以东海-赣榆断裂为界,苏鲁造山带可分为南部和北部,两部分在后期构造活动方面差异显著.
Airborne gravity and aeromagnetic data are very effective and important for solving the basic geological structure problems.Based on the newly acquired high-precision airborne gravity and aeromagnetic data,the 1∶250 000 gravity and magnetic anomalies map were compiled,the gravity and magnetic field characteristics with regional geological and geophysical materials were analyzed,the basement faults including Tanlu fault belt,Sangxu-Lianyungang fault belt,Donghai-Ganyu fault belt and Wulian-Taoyuan fault belt were recognized.It is believed that the south boundary of Sulu orogenic belt is SangxuLianyungang fault,the northern basement of the fault belongs to North China plate and the southern basement belongs to the Lower Yangtze plate.Bounded by Donghai-Ganyu fault belt,the Sulu orogen can be divided into southern and northern segment,which have quite different tectonic movements.
