广东阶地的特征

Features of Guangdong Terrace

在全面论述广东阶地的特征后指出，第一级阶地的上更新统堆积时间可长达１０万年，反映这期间广东相当大的面积无明显构造抬升．在基面长期类高条件下，在上更新统内发育了许多侵蚀面，是造成同一高程的阶地沉积物年龄差异的主要因素。

After overall discussion research on Guangdong terrace in this paper,it is pointed out that time of Q 3 sediment accumulation is as long as 10 5 years,reflecting suitably great area of Guangdong is not clearly structural lift during this time,many erosion surfaces formed in the Pleistocene Epoch in condition of long term similar level base are a main factor creating age difference of terrace sediment at same height,moreover,the structural condition is yet created for forming marine erosion platform wide tens and a hundred metres or so on bedrocks coast along the coast zone. Powers of the terrace deform are yet probed in this paper.
