| 摘 要： | 通过对塔里木盆地巴麦地区寒武—奥陶系地震、沉积特征研究,运用地震、钻井岩心资料,对该区层 序特征分析,巴麦地区经历了由碳酸盐岩缓坡型台地向镶边斜坡型台地演化,主要控制因素是构造活动和海平面变化早— 中寒武世为缓坡型台地演化阶段,由于海平面频繁升降变化,台地边缘经历3次迁移;晚寒武世该区处于拉张环境形 成被动大陆边缘,海平面开始上升,发育镶边斜坡型台地,海平面相对上升速率小于沉积物供应速率,台地边缘向 盆地方向迁移；早奥陶世,海平面上升速率加快,大于沉积速率,台地以追补型叠加形式向台地方向迁移.

| Abstract: | By Cambrian-Ordovician sedimentary and seismic characteristics analysis in Ba-Mai aera of Tarim Basin.Though the use of seismic,drilling core data and sequence characteristics,The results show that those area experienced evolution of the ramp-type carbonate platform slope to the edge of platform-type.The main control factor is the tectonic activity and sea level changes.the evolution of ramp-type platform in Early-Middle Cambrian,due to frequent movements of sea level changes,platform margin has experienced... |
