These groups appear to have formed simultaneously, as no specific stratigraphic sequence is evident.

In some stratigraphic sequences, there is clearly a variation in color between different strata.

Therefore, highs are not good places to study stratigraphic sequences as the sequence may be less detailed or even absent.

The stratigraphic sequence is firmly dated spanning the last 11,700 cal years.

The stratigraphic sequence, which is the basis for the area's diversity of landscape and habitat, comprises:

From this, a stratigraphic sequence of developments evolved with "craft production and social stratification".

This preservation problem among others further make the task of establishing stratigraphic sequences a little bit difficult.

The units are shown in stratigraphic sequence (the youngest at the top of the table, oldest at the bottom).

These attributes of the mercurian crater population allow stratigraphic sequences to be constructed over large regions.

These stratigraphic sequences are among the thickest collections of Permian rocks in the world.
