摘要
从沉积-构造演化的角度,以时间为线索,通过区内侏罗系、白垩系及古近系等地层岩相、地层原始沉积厚度、残留厚度的对比与分析,揭示了鄂尔多斯盆地西南缘陇县地区在南北方向上具“翘翘板”式的沉积-构造演化规律。通过构造控煤作用分析,预测出该区存在南北两个含煤有利区,并得到地震勘探验证。
From the point of view about sediment-structures evolution the uneven sediment-structure evolution movement-laws along north-south direction in Longxian region of southwestern Ordos Basin have been found with time clues,and by analyzing and comparing about the thickness of the initial formation and the residual of the Jurassic,Cretaceous and Paleogene system.Two advantaged coal-bearing districts in the north and south direction have been forecasted based on the analysis of structure coal-control action.It h...
