“…Since the faults increase their length during repeated earthquakes (Jackson and Leeder 1994), the long faults in the study area were formed during long period of seismic activity. As stated previously some faults in the study area are segmented, and then the faults increase their length by coalescing of neighboring segments by local earthquakes (see also Gillespie et al 1992;Davis et al 2005). The correlation between the paleostresses and the present-day ones (Tables 3 and 6) shows that there is a change in tectonic conditions and stress states.…”

The basement rocks, Neogene sediments and Quaternary alluvial deposits in the Abu Dabbab area, Eastern Desert of Egypt, are deformed by N-S, NE-SW, NW-SE and E-W trending faults. Complex cross-cutting relationships show a complicated history of initiation and reactivation of these faults. The recent fault scarps demonstrate different morphologies, modes of formation and relative ages. Recurrent, step and successively reactivated faulting was likely responsible for the exhumation and neo-formation of the fault scarps. Capture, deep incision, offset and reversal in flow direction of streams are the main drainage modifications induced by active faults. The concealed and active faults are associated with high drainage density anomalies. Segmentation phenomenon is common for all fault trends. Microearthquakes are concentrated at the intersection zones of faults and caused by upper crustal strike-slip, oblique-slip, reverse and normal faults. The paleostresses are not consistent with the present-day stress fields. The present-day NE-SW extension across the Red Sea combined with a local multidirectional tension led to reactivation of old faults and initiation of new fault trends.

“…The first step is to identify planetary landforms that can confidently be interpreted as having formed by deformation. Tanaka et al (2010) review the main criteria for recognizing and interpreting planetary structures such as faults that are comparable to those used by field geologists and geologic mappers in their interpretation of outcrops, aerial and satellite images, and topographic data (e.g., Davison, 1994;Schultz, 1999;Peacock, 2002;Davis et al, 2005;Nemčok et al, 2005;Cunningham and Mann, 2007). The type of fault is deduced from the nature of its displacement field (e.g., Pollard and Segall, 1987), which is related to its kinematics; all three main types of faults (normal, strike-slip, and thrust) have long been recognized in planetary images of various solar system objects (see Strom, 1972;Masursky et al, 1978;Schultz, 1976;Wilhelms, 1987;Tanaka et al, 2010).…”

“…Displacement-to-length ratios are typically 6.0 Â 10 À3 or 6.7 Â 10 À3 for faults on Mars (Watters et al, 1998;Wilkins et al, 2002) and 6.5 Â 10 À3 for faults on Mercury (Watters et al, 2000(Watters et al, , 2002. On Earth, this ratio is typically between 2 Â 10 À2 and 5 Â 10 À2 over a range of tectonic settings and rock types (Cowie and Scholz, 1992;Clark and Cox, 1996;Schlische et al, 1996;Schultz and Fossen, 2002;Davis et al, 2005). Under-displacement of faults on Mercury and Mars can be attributed to these planets' smaller gravitational accelerations relative to Earth .…”

“…[3] Reverse-fault-bounded mountain ranges propagating into a foreland basin commonly initiate either as a single, localized structure which gradually lengthens along strike with increasing amount of shortening, or as several fault segments which eventually coalesce or overlap [Dawers et al, 1993;Cartwright et al, 1995;Davis et al, 2005]. In either case, the active range front likely lengthens as displacement accumulates on the range-bounding faults.…”

Exhumation of basement‐cored uplifts: Example of the Kyrgyz Range quantified with apatite fission track thermochronology

[1] The Kyrgyz Range, the northernmost portion of the Kyrgyzstan Tien Shan, displays topographic evidence for lateral propagation of surface uplift and exhumation. The highest, most deeply dissected segment lies in the center of the range. To the east, topography and relief decrease, and preserved remnants of a Cretaceous regional erosion surface imply minimal amounts of bedrock exhumation. The timing of exhumation of range segments defines the lateral propagation rate of the range-bounding reverse fault and quantifies the time and erosion depth needed to transform a mountain range from a juvenile to a mature morphology. New multicompositional apatite fission track (AFT) data from three transects from the eastern Kyrgyz Range, combined with published AFT data, demonstrate that the range has propagated over 110 km eastward over the last $7-11 Myr. On the basis of the thermal and topographic evolutionary history, we present a model for a time-varying exhumation rate driven by rock uplift and changes in erodability and the timescale of geomorphic adjustment to surface uplift. Easily eroded, Cenozoic sedimentary rocks overlying resistant basement control early, rapid exhumation and exhibit slow surface uplift rates. As increasing amounts of resistant basement are exposed, exhumation rates decrease while surface uplift rates are sustained or increase, thereby growing topography. As the range becomes high enough to cause ice accumulation and to develop steep river valleys, fluvial and glacial erosion becomes more powerful, and exhumation rates once again increase. Independently determined range-normal shortening rates also varied over time, suggesting a feedback between erosional efficiency and shortening rate.
