| 摘 要： | 本文据茅山地区1∶20万大比例尺布格重力异常及其延拓结果,并结合爆破地震和天然地震等资料,分析了茅山断裂带的延伸规模及切割深度.认为茅山断裂带属地壳断裂;茅山断裂带与近东西向的石桥—无锡隐伏地壳断裂相交汇构成了溧阳地震的深部构造条件.

ON THE RELATIONS BETWEEN DEEP-SEATED CRUSTAL STRUCTURES AND GENESIS OF LIYANG EARTHQUAKES IN MAOSHAN AREA-A NEW IDEAS |
| |
| Abstract: | In this paper,according to the data of the Bouguer anomaly observed (a scale from 1 to two hundred thousand) and Bouguer anomaly through extending up to 10,20,30km,the extending scale and deepth of Maoshan fault zone were analised.The authors suggest that the Maoshan fault Zone extends through crustal and the two group fault zones i.e.Maoshan fault zone of NNE-trending and Shiqiao-Wuxi blind fault zones nearly EW-trending,as well as intersecting of two group fault zones,are considered to be the deep tectonic factors of a genesis of Liyang earthquakes. |
