These outcrops provide excellent locations for understanding how large-scale folds grow during thrusting.
The Corbel section runs across the faulted forelimb of an anticline associated with a
thrust. We can visit this structure to see the range of minor faults that are associated
with the main thrust. These are well-exposed in a road section - the sketch of which can
be used to zoom in on detailed parts of the outcrop.
The history of large-scale folding (represented in the road section by
steeply-dipping beds) and minor faulting can be reconstructed - as shown on the synthetic
sketch at the foot of this page.
You should plot the kinematic data from the minor thrusts onto a
stereogram.

| Looking NE onto the Corbel structure. The prominent limestone cliff units
define the fold structure (also seen in the introductory images for these Chartreuse
sites).The readily eroded lower Cretaceous shales lie in the cultivated valley to the
right of the road section. These outcrops provide excellent locations for understanding how large-scale folds grow during thrusting. |

| This cartoon shows a simplified model of how the large scale folds and the smallscale faults relate. |
