All structures are tectonic, extension estimates are roughly comparable for all failure modes, and there is a distinct absence of bedding-parallel detachments with normal separation. These observations imply that different beds failed coevally or semi-coevally in extension. All contractional structures are consistent with earliest Jurassic inversion. The normal faults present within the quarry are the smallest normal faults studied in detail to date. They occur both as isolated features and as segments of relay systems.
Maximum displacement occurs at fault centers and tapers to zero at the tips.
These small faults extend the global length-displacement data set from 7 to 9 orders of magnitude of fault length, and demonstrate that maximum displacement scales linearly with length over that scale, suggesting that fault growth is scale invariant. These small faults can be divided into two subsets based on length and their spatial distribution within the rock volume. The fault shields are ellipsoidal in shape, approximating the deformation fields of the master faults. This spatial distribution of faults complicates strain estimates.
