摘要
从石油的地质的探索基于第一手的材料，我们在 Songliao 盆在早白垩纪和地下室裂缝的分发做了构造发展的详细研究。这个时代的沉积特征和盆的 tectono-paleogeography 被详细说明。结果证明在它的早阶段， Songliao 盆被主要，湖外形在山之中在发展了的分开的指责的盆描绘。它逐渐地在早白垩纪的迟了的阶段期间成为了一个湖。在这个时期期间，在 Songliao 盆的差错活动变化了从一对安静开发狂暴，来自小分开的湖的水区域到一个大湖，沉积外形在被划分成不对称的东方、西方的部分。在盆，一个暴烈的碎屑状的岩石冲积的扇子系统发展了，一个扇子 delta-lake-small 三角洲河系统主要被扔。我们的研究也证明地下室裂缝不仅在早白垩纪控制了差错消沉和构造开发的分发，而且也穿上效果沉积，来源区域和河系统的取向，它决定早白垩纪的 tectono-paleogeography。
Based on first-hand material from the geological exploration of petroleum,we made a detailed study of the tectonic development in the Early Cretaceous and the distribution of basement rifts in the Songliao Basin.The sedimentary characteristics of this epoch and the tectono-paleogeography of the basin were expounded.The results show that in its early stages,the Songliao Basin was characterized by a detached faulted basin in which mainly lake facies developed among mountains.It became gradually one lake during the late stages of the Early Cretaceous.During this period,the fault activity in the Songliao Basin changed from a turbulent to a quiet development,the water area from small separated lakes to one large lake,in which the sedimentary facies were divided into asymmetric eastern and western parts.In the basin a volcanic clastic rock-alluvial fan system developed and a fan delta-lake-small delta-river system was mainly deposired.Our research also shows that the basement rifts not only controlled the distribution of fault depressions and the tectonic development in the Early Cretaceous,but had also an effect on the orientation of sedimentation,source area and river system,which determine the tectonopaleogeography of the Early Cretaceous.
