To construct a geologic cross-section, first take a geologic map of the target survey area.

This video will illustrate the process of creating a geologic cross section, and highlight some of the extensive uses of this geological tool.

Taken together, rock type, position, and orientation, are used to create a geologic cross-section.

A geologic cross section of the Los Angeles Basin from the southwest to northeast.

Hence we can indeed use these cross-cutting relations to establish the relative ages of geological features.

A geological cutaway of the area around the future disposal facility site and the laboratory where the research is being carried out shows the Callovo-Oxfordian layer.

Now that we are familiar with the principles behind the construction of a geologic cross section, let's take a look at how this is carried out on an example map.

Back at the winery, we went down into the cellar to see the exposed cut of the ground to better understand the kimmeridgian soil that gives Chablis wines their specificity.

In terms of the total vertical profile exposed and the low elevation, Gale offers attractions similar to Mars' famous Valles Marineris, the largest canyon in the solar system.

The result is a geologic cross section, a view that essentially provides a cutaway image, much like one would see on a canyon wall or in a roadcut.

Formation overburden is directly measured at one or more locations in the borehole, and a log of formation overburden is generated using the measured overburden pressures and conventional geophysical data.

One of the primary uses of the geologic cross section is to reconstruct folds and faults that are somewhat cryptic, as a result of erosion removing their surface features.
