【摘要】 本文首先简要地介绍了前陆盆地的一般概念及其构造—沉积演化模式,然后根据钦州—玉林地区的沉积特征及有关的区域地质资料进行综合分析,并与国外典型前陆盆地进行对比。我们认为,前人资料中的“钦州残余海槽”,应是云开碰撞造山带的前陆盆地,并尝试恢复钦州前陆盆地的构造—沉积演化过程。更多还原

【Abstract】 Beginning with the brief introduction to the general concepts of foreland basin and its tectono-depositional model, the paper comprehensively analyzes the sedimentary features of Qinzhou-Yulin area and related regional geological data and compares them with the typical foreland basins in the foreign countries. The paper considers that the so-called Qinzhou residual trough should be the foreland basin of Yunkai collision zone and tries to restore the tectono-depositional evolutionel process of Qinzhou forelend basin.更多还原
