摘要/Abstract

摘要： 在前人研究基础上，并结合地质、地球物理、地球化学等资料，审视郯庐断裂带的力学性质、演化阶段、动力学背景以及深部岩石圈活动对郯庐断裂带和渤海湾盆地形成的影响，提出一些与前人研究成果不同的认识：郯庐断裂是追踪继存性断裂；郯庐断裂南段在晚古生代可能存在转换断层；渤海湾盆地形成与地幔柱有关，与郯庐断裂扭动关系不大等。最后质疑3个问题与地学同仁探讨。

关键词: 郯城-庐江断裂带, 演化阶段, 动力学背景

Abstract: Based on the research results of the past, using the integrated geological,geophysical, geochemical etc. data at hand, and combining recent research results of lithosphere evolution of Eastern China, this paper is concentrated on the mechanics character, evolution phases and dynamics background of TanchengLujiang fault zone, and on the influence of the deep lithosphere activity on the TanchengLujiang fault zone and on the formation of Bohai bay basin by bringing up some different cognition from the past studies. For example, the TanchengLujiang fault zone may be a transform fault zone in south section during Late Paleozoic, and the formation of Bohai bay basin was not related to the TanchengLujiang fault zone. Finally three questions are raised to be discussed.

Key words: TanchengLujiang fault zone, evolution phase, dynamics background
