泥盆纪弗拉期-法门期界线是地球历史上显生宙最重大的事件界线之一.运用化学-生物地层学方法,在新疆塔里木盆地揭示了能与华南相当事件层进行对比的弗拉期-法门期界线事件.研究结果证明,在巴楚小海子剖面,弗拉阶-法门阶界线位于巴楚组中段底部,重要的油气储层-东河砂岩的时代应为弗拉期,同时镍异常和石膏层沉积很可能是裂谷热液活动的结果.
The Devonian Phrase-Famenian boundary is one of the most significant event boundaries of the Phanerozoic in the history of the earth. Using the chemical-bio-stratigraphic method, Flame, which can be compared with the equivalent events in southern China, is revealed in the Tarim Basin, Period-Famenian boundary line.The result of the study shows that in the Bachu-Xiahaizi section, the Fulajie-Famen boundary is at the bottom of the middle section of the Bachu Formation, and the era of the important oil and gas reservoir, the Donghe sandstones, should be the Phra period. Meanwhile, Nickel anomalies and deposits of gypsum are likely the result of rifting hydrothermal activity.
