The erosional surface dissected by such valleys may subsequently become an unconformity in the stratigraphic sequence . 被这种河谷切割的侵蚀面后来可能成为地层层序中的不整合性。
Combination of these logs, supported by plotted sample description, are used in establishing precise subsurface stratigraphic correlations . 现在综合应用这些测井方法，再结合岩样描述，进行精确的地下地层对比。
Most geology professors concerned with stratigraphic research direct their attention to outcrop stratigraphy rather than to subsurface stratigraphy . 从事地层学的多数地质学教授的注意力主要放在露头地层学而不放在地下地层学上。
