摘　　要：通过对庐枞火山岩盆地及周边重、磁资料以及实测高精度重磁剖面的综合解释,揭示了庐枞盆地的莫霍界面隆起带的特征,确定了郯庐断裂的位置,对庐枞火山岩盆地的边界断裂以及区内主要断裂构造进行了探讨,圈定了盆地范围,初步推测火山岩盆地的底界埋深约2000~2500m左右,为该区找矿工作提供了重要的参考资料。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 2000-2500m or so.

关 键 词：重磁资料 断裂构造 火山岩盆地 罗河式铁矿
