摘要
文章将龙门山地区泥盆系划分为四个沉积旋回,即四个地层层序,建立了该区泥盆纪海相碳酸盐锶、碳同位素地层曲线,并将同位素演化与沉积旋回结合起来研究该区泥盆纪的海平面变化。
This paper divided Devonian strata of the Longmen Mountain into four sedimentary cycles or four sequences and established Sr and C isotope stratigraphic curves for marine carbonates of Devonian. The sea level fluctuation of Devonian can be studied according to the combination of isotope evolution and sedimentary cycles.
