摘要:
1. Syclinal warping at the end of the Cretaceous time?(Phase Ⅲof Yenshan Movement?).Intermont sedimentation.Deposition of the lowerand middle portions of the Kuanchuang Series during the Eocene(and earlyOligocene?)time. 2. Block-faulting and progressive tilting during the late Oligocenetime(Nanling Movement).Accumulation of the "bajada breccias" in con-nection with the faulting and the inauguration of the Tanghsien consequentdrainage system. 3. Tanghsien erosion to full maturity during the Miocene time. 4. Prolonged period of chemical weathering.Fossil soils withmanganese-iron pisolites and karst surfaces formed(Pliocene). 5. Deposition of gravels(Late Pliocene?). 6. "Z erosion" of moderate dissection followed by the accumula-tion of the Concretionary Reddish Loams (Lower Pleis cene). 7. Chingshui dissection along old lines,followed by the deposition ofbrownish-gray loams and loess of the Malan epoch(Upper Pleistocene). 8. Present cycle of erosion and deposition.
