Complete Title: En echelon magnetic anomalies in the Western Indian Ocean: a By extending the curved fault solutions, the duplex system is seen to be bound

Abstract--Numerous strike-slip fault zones in granitic rocks of the Mount Abbot quadrangle, California, unconnected left-stepping echelon faults were linked by.

The term 'en echelon' refers to closely-spaced, parallel or subparallel, overlapping or step-like minor structural features in rock (faults, tension fractures), which lie oblique to the overall structural trend. Conjugate deformation structures are related in deformational origin. Extensional stresses create fractures that can infill with calcite. Aerial view of Salton Sea, with the approximate locations of the southern San Andreas and Imperial faults. Note how right-lateral slip on the two en-echelon faults drive extension between them. click here to see more photos of the San Andreas fault system, or click here to see a photo geology tour of Death Valley, California . Two parallel sets of en echelon veins in sandstone near Lehigh Gap, Pennsylvania, with hammer for scale.

Note northern faults forming - more pure transcurrent. Why? as thicken crust resistance increases, and more energy efficient to form new crust? San Andreas fault system. Movement history?

Both echelon and pod folds occur in the Roan Antelope deposit, Northern Rhodesia, Africa. en The structures of the fault block indicate a compression and uplift of the Ibbenbüren fault block by strike-slip movements at the en echelon Osning lineament. In connection with the uplift compressional and lateral shearing movements produced the south vergent Osning thrust within the overlaying strata.

4, Fig. 9). They are close to the DNF and are predominantly thrust faults (horsetail splays) that are related to the sub-salt structural highs.

In connection with the uplift compressional and lateral shearing movements produced the south vergent Osning thrust within the overlaying strata.

They originate as tension fractures that are parallel to the major stress orientation, σ 1, in a shear zone. The term ' en echelon ' refers to closely-spaced, parallel or subparallel, overlapping or step-like minor structural features in rock (faults, tension fractures), which lie oblique to the overall structural trend. Conjugate deformation structures are related in deformational origin. Extensional stresses create fractures that can infill with calcite. Three of the faults, known as en echelon faults, were parallel but offset from each other, while the fourth fault was perpendicular to and crossed the first. with a series of en echelon oblique‐normal faults that strike obliquely to the SAF and may accommodate the missing deformation. This study presents a suite of analyses that are helpful for proper mapping of faults in locations where high‐resolution topographic data are available.

Through further strain Feb 13, 2008 nearly en echelon normal faults of late Cenozoic age and on the east Thrust faults of Pennsylvanian age cut surface rocks in the Marathon As a result, en-echelon and/or overlapping flower structures develop along the curved basement strike-slip fault system.

By better understanding this convection signature, both between faults and in the overlying host, future geothermal projects may be able to identify and exploit these convective systems. en The tectonic reason for rifting in such a case could be the strike separation along a series of en echelon faults similar to those of the Gulf of California. Giga-fren fr Dans ce cas, la raison tectonique de formation du rift pourrait être due à la direction de séparation le long d'une série de failles en échelon , comme dans le golfe de Californie. with a series of en echelon oblique‐normal faults that strike obliquely to the SAF and may accommodate the missing deformation.
