鄂尔多斯盆地中晚三叠世延长期沉积演化
|
摘要
基于多年对鄂尔多斯盆地中上三叠统延长组的研究成果,结合近年来对盆地东、南邻区宁静盆地、沁水盆地、济源盆地、南召盆地等同期地层的野外实测以及地球化学、年代学等的研究结果,对鄂尔多斯盆地中晚三叠世延长期的岩性特征、地层厚度、地层接触关系、沉积相类型等进行对比研究。结果表明,研究区周缘中晚三叠世的岩性粒度变化、地层厚度及地层上下接触关系与鄂尔多斯盆地沉积背景具有一致性;沉积相带演化从时间尺度和空间尺度上讲,从邻区向鄂尔多斯盆地内部过渡变化符合瓦尔特相律,符合中晚三叠世华北板块构造的演化背景。研究后认为,中晚三叠世,周缘盆地与鄂尔多斯盆地应属同一个大型沉积盆地,这将中晚三叠世鄂尔多斯原型盆地向东部和南部延伸,包括了宁静盆地、沁水盆地、济源盆地、南召盆地等盆地。该研究为中晚三叠世鄂尔多斯盆地原始沉积面貌的恢复提供了新的依据。
Based on the author's research results of Middle-Late Triassic Yanchang Formation in Ordos Basin for many years,and combined with the field measurements,geochemistry and geochronology studies of synchronous strata in the eastern and southern adjacent areas of Ningjing Basin,Qinshui Basin,Jiyuan Basin and Nanzhao Basin in recent years,the lithological characteristics,stratigraphic thickness,stratigraphic contact relationship and sedimentary facies types are studied comparatively. The results show that the variation of lithologic grain size,stratum thickness and the contact relationship between upper and lower strata of the abovementioned periphery are consistent with the sedimentary background of the Ordos Basin,and that the evolution of sedimentary facies belts from the adjacent areas to the interior of the Ordos Basin conforms to the Walther facies law and to the tectonic evolution background of the North China Plate of the Middle-Late Triassic. Thus the Middle-Late Triassic peripheral basin and the Ordos Basin should belong to the same large-scale sedimentary basin. The Ordos prototype basin of the Middle-Late Triassic should extend to the East and South and include the Ningjing Basin,Qinshui Basin,Jiyuan Basin and Nanzhao Basin. This study provides a new basis for the restoration of the original sedimentary features of the Ordos Basin in the Middle-Late Triassic.
