在考虑不同构造层之间剥蚀与沉积变化关系的基础上, 认识到剥蚀沉积规律的
存在。对沾车地区构造特征进行了认真分析认为, 不论哪个潜山, 也不论哪个构造部位, 它们
都应当遵循该规律。提出潜山遭受风化剥蚀的时间越长, 残存地层越老越薄, 上覆盖层则越新
越薄; 反之, 潜山遭受风化剥蚀的时间越短, 残存地层越新越厚, 上覆盖层则越老越厚。应用该
认识在检验划分结果、指导地层划分方面具有重要意义。

A fter considering the relations o f denudation and
sedim en t presented on different con fo rm ations, analyzing the
structura l character istics of Zhan-Che a rea, the conc lusion is
tha t the sam e denudation rule is applied to the d ifferent
underg round m assifs and the different structu ra l positions. To
the fo rm ation of underg round massi,f the longer wea ther ing
denudation period is, the o lder the rem a ined form ation is, the
younger the ove rburden rock. On the contrary, the sho rter
w eathe ring denudation per iod is, the young er the rema ined
form ation and the o lde r the overbu rden ro cks. Th is paper
spec ifies the im po rtan t sign ificance of the denudation ru le
app ly ing to check ing and directing form ation partition.
