| 摘 要： | 通过沉积盆地地壳动力学分析及沉积体系的识别与划分，首次提出并建立了龙门山中生代前陆盆地等时地层格架的充填生长模式。中生代盆地的发育、生长可分两个时期：第一个时期（Ｔ３３—Ｊ１１）为大巴山－米仓山前陆盆地期，它是以北部大巴山、米仓山为物源区向南展布；第二个时期（Ｊ１２—Ｋ１）为龙门山－大巴山叠合前陆盆地期。早侏罗世中、晚期龙门山完全升起成为陆源剥蚀区，此时大巴山、米仓山仍为物源区，这两个物源区为线状并呈钝角相交向东南展布。

| Abstract: | Mountains Longmen foreland basin in Mesozoic is a marginal foreland basin.By dynamic sedimentary basin research and study on depositional system,a foreland basin-growing model has been constructed.The basin developing process is divided into two stages: the first stage (T33 J11) is Daba-Micang Mountains foreland basin stage with the sediments source in north and the basin center in south. The second stage (J12 K1) is mountains Longmen stacking foreland basin stage with sediments sources in both Mountains Daba and Mountains Longmen. |
