郯庐断裂中段古裂谷的基本特征

The evidence of the paleorift (J_3-K_2) in the middle section of the Tan-cheng-Lujiang Fracture Zone is described here in detail. A preliminary conc-lusion about the paleorift is obtained through reconstruction of paleotectonicsand paleogeomorphology, elucidation of magmatic evoluttion and deep struct-ures, and comparison with some typical rifts in the world.
