Widely-separated sediments that occur between correlatable unconformities could be compared with each other.

可以将在相关不整合面之间出现的大范围沉积物相互比较。

Unconformities are surfaces of erosion or non-deposition.

不整合面是侵蚀面或无沉积面。

Regional unconformities and sedimentary boundaries record the rhythm of uplifting;

区域性不整合面和沉积界面记录了隆升的阶段性；

The fact that unconformities are usually the strongest reflections often makes this task easier.

不整合面一般为最强反射这一事实常使该项工作较易进行。

The transporting and conducting system is consisted of sandstone layers, unconformities, faults and volcanic intrusions;

输导系统由砂层、不整合面、断层、 火成岩侵入体组成；
