in Strike-Slip Deformation, Basin Formation, and Sedimentation, Soc. Lateral displacements of several kilometres inferred along these arrays may be related to tectonism in Tharsis. The strike-slip faulting predates or overlaps periods of wrinkle-ridge growth south-east of Valles Marineris, and some wrinkle ridges may have nucleated and grown as a result of strike-slip displacements along the echelon fault arrays. Here I identify and document several well preserved examples of martian strike-slip faults and examine their relationships to wrinkle-ridges. However, careful study of Viking Orbiter images is revealing that strike-slip faults may be present on Mars 7. Aerial photo of the San Andreas Fault in the Carrizo Plain.

Thus, Mars is believed to have evolved without plate tectonics or other large-scale lateral motions of the lithosphere 6. EarthWords is an on-going series in which we shed some light on the complicated, often difficult-to-pronounce language of science. This view is based on the lack of significant lateral offset of pre-existing markers such as craters across suspected faults. First, the platform margin was divided by strike-slip faults into three distinct segments to show two weak-rimmed margins and one interbedded rimmed margin. In contrast, strike-slip faults have been considered to be extremely rare or absent on Mars 4,5. Further, it was found that the strike-slip fault had some effects on the mound-shoal bodies of the Ediacaran Dengying Formation. 1 Introduction Global carbonate formations are rich in hydrocarbon resources, and will likely be the most important area for future oil and gas exploration and development. THE surface of Mars shows abundant evidence of extensional and contractional deformation in the form of normal faults, grabens and wrinkle ridges 1–3. Strike-slip faults are important hydrocarbon migration paths, and their multistage activities have different controlling effects on hydrocarbon accumulation.
