Remote sensing images reveal that the nappe structures in Jurong Basin might relateto E-W or NEE striking arcuate linear structures in the basin.The tenso-shear fault linear structural system in Ningzheng Mountains that stretches into the basin once had been in-terpreted to be imbricate structures in seismic profile by mistake rather than nappe structures.According to v-circular structure-tonal anomaly model of remote sensing

hydrocar-bon tone halos are mainly located in the east side of Jurong gravitational high

suggestingthat the distribution of the halos is controlled by NNE-strike torsion structures and their subsidiary faults

and by NW-strike cross faults and near NS-directional faults.Thus thehalos could be considered as ground indication of hydrocarbon traps.It is proposed thatnon-seismic techniques such as remote sensing

geochemical exploration

radio activeprospecting should be strenghed in the study area

and a synthetic assessment model of hy-drocarbon traps should be established so as to make a break throug in its oil and gas explo-ration.This is the general trend for hydrocarbon exploration in Paleozoic and Mesozoic carbonate rocks in the middle and lower reaches of the Yangtze River.
