摘要
After integrated interpretation of gravitational, magnetic data and measured high-precision gravitational-magnetic profile for the Lu-Zong volcanics basin and the periphery, this paper unveiled the Moho uplift features of the basin, determined the location of the Tan-Lu fault, discussed the border fault of the basin and some major faulting structures in the area,outlined the basin, and initially proposed the lower limit of the basin at depth of 2 000~2 500 m or so.
