| 摘 要： | 震旦纪(埃迪卡拉纪)-寒武纪之交(SCB)是华南裂谷盆地到被动大陆边缘盆地演化的重要转折期,也是华南古生代最重要的烃源岩发育时期.铜仁坝黄SCB附近的沉积序列和沉积地球化学研究表明,该时期沉积具有热液活动和缺氧沉积的双重特征,并伴有火山活动,结合区域地质调查成果,作者提出了地壳伸展-差异升降-热液上升(伴随火山活动)-...

| Abstract: | It was a very important transition from Precambrian to Cambrian Period,because during this time the basin nature not only had accomplished the change from rifting basin into passive margin basin,but also the most important source rocks of Paleozoic had developed in south China.So,deep studying the sedimentary sequence and depositional environment of this time is the key to recognize and understand the developing mechanism of high grade source rocks,and the dynamic setting of basin evolution.The research of ... |
