Integrating geophysical datasets for fault spatial distribution and activities analysis: a case study of Changxing-Fenghua Fault in Hangzhou Bay

摘要

The Changxing-Fenghua Fault (CFF),which is a regional fault trending NVV-SE diagonal across the Hangzhou Bay region,changed the NE-SW trending tectonic frameworks formed in Indosinian movement.Therefore,this fault is important for the exploration of mineral/oil resources in this region.However,determining the distribution of CFF is still a challenging task because CFF consists of a series of NVV-SE trending faults which are discontinuous,parallel to each other or en-echelon with right order,which are hard to interpret In this paper,four different categories of geophysical datasets (i.e.medium-spatial resolution optical remote sensing dataset,aeromagnetic,Bouguer gravity and seismic datasets) are integrated for determining the spatial distribution of the CFF and analyzing the activity in Mesozoic and Cenozoic.
