” Up-dip displacement of layered series along dip-segmented thrust faults generates fault-bend folds. Some low-dip thrust faults terminate up-section and are capped by buckle folds, to be offset later by the growing fault. Folds with thrust-faulted cores are named “fault-propagation folds.”...
Naturally formed faults typically are segmented. The detailed microstructural examination of a small brittle fault in the Shawangunk Mountains of Ulster County, New York provides new insight into the segmentation process. In brittle faulting the propagation directions of faults can be determined from the...
We assume that shear zones have the same dip as overlying brittle faults5,18,59,68,69. We make this assumption because where the structure of the middle/lower crust beneath areas of extension has been clearly imaged with high quality seismic reflection data (e.g., the DRUM profile offshore...
Although previous studies have suggested that transforms may be segmented, and it has been hypothesized that variable water infiltration into the lithosphere plays a role, our study provides new constraints on the Earth properties that can result in such phenomena. Multiple overlapping faults located ...
However, further south, seismic quality is in places relatively poor, especially where thick carbonates dominate the surface geology (e.g., parts of deep seismic reflection line CROP 1175; Fig. 1). Low-angle extensional detachments/shear zones have been proposed to explain low-angle reflections ...
scheme of a previous elastic half-space analysis [Smith and Sandwell, 2003], obtained from digitizing the major fault strands along the SAF System from the Jennings [1994] fault map; segmentation modifications were made in order to better accommodate along-strike variations in fault-segmented ...

The north-west margin of the Dampier sub-basin is characterised by a strongly segmented fault pattern. NE trending faults define the edge of the Rankin Platform, and separate it from the Kendrew Trough. However a secondary set of NNE trending faults define smaller scale graben on the edge of...
or segmented. Because the purpose of the mapping was to determine the variation in dike azimuth, the map does not provide information about the dimensions (e.g., length and aperture) or dip of the dikes. We determined the trend and centroid coordinates for each dike segment using the field...
