摘要

摘要: 基于黄土沉积速率与粒度的相关性提出了一种通过求解代数方程组而确定黄土地层年龄的新方法。以洛川剖面为例，用该方法确定了其Ｓｌ顶部至Ｓ２底部深度－年龄的转换关系，与ＳＰＥＣＭＡＰ高分辨率的深海氧同位素记录的对比表明了该方法在确定黄土序列年龄上的有效性。

Abstract: On the basis of linear correlation between loess sedimentation rate and grain size,a new method of establishment of loess sequence age was developed. In this method, we assume that there is a linear relationship between the loess sedimentation rate R and the grain size S at the same horizon in a loess sequence,that is, S=aR+b,where a and b are coefficients awaiting determination. Supposing that the loess between two time control points is divided into n layers.the depths of which are indicated by Δh₁,Δh₂......Δh_n and the time Δt₁,Δt₂......Δt_n,respectively,a system of equations can be established by proceeding. fi(Δt₁,Δt₂,......Δt_n-1,Δt_n,a,b)=0 i=1,2......n,n+1,n+2 in which Δt₁,Δt₂......Δt_n,a and b are unknown numbers. As this is a system of special nonlinear algebraic equations,which consists of n+2 equations,its numerical solution will be obtained with a iteration method.In this way,we can carry out a transformation from depth to age for a loess sequence. As an example,the depth-age transformation in the Luochuan loess section
- loess sedimentation rate /
- drain size /
- depth-age transformation /
