PRELIMINARY STUDY ON THE STRUCTURAL CHARACTERISTICS OF THE YISHU FAULT ZONE AND ITS SURROUNDING AREAS BY USING GRAVITATIONAL AND MAGNETIC SURVEYING DATA

摘要:

Abstract:

The Yishu Fault Zone(a segment of the Tancheng--Lujiang Fault Zone in Shandong Province)and the structures in its surrounding areas have been clearly shown on the gravitational and magnetic maps;the Yishu Fault Zone is expressed as a NE-trending gravity gradient zone and a ran- tdom magnetic zone,whereas the boundary between the Jiaonan Uplift and he Jiaolai Depression on the east side of the Yishu Fault Zone is indicated by a distinct gravity gradient and an aeromagnetic linear normal anomaly, both of whic...
