Stratigraphical columns

A column is a graphic representation of the several materials that we can find, in a determinate zone, as it has sedimented, the most ancient materials in the inferior part and the most modern in the superior part. To construct a stratigraphical column, it is necessary to measure in the field the thickness of all the shapes, starting on the lower and continuing towards the superior ones. It is necessary to avoid the tectonic structures that can remove a succession part or to duplicate it. In a map they can put on several columns, carried out in different places, in order to compare them and visualize how the sediments of a same age (color) change laterally of power (thickness) or of facies (type of sediment).

 

A stratigraphic column is a graphic representation of the various materials that we can find in the way they have been deposited, the oldest in the lower part and the most modern in the upper part. To build a stratigraphic column, the thickness of all layers must be measured in the field and tectonic structures must be avoided. Various columns can be placed on a map in order to compare and visualize how sediments of the same age (color) change laterally in power (thickness) or facies (types of sediments).
