“…Regional and local slip rates on various segments of DST system have been measured by several methods. Quaternary slip rates in the range of 2 to 8 mm/yr were estimated based on offset surface features along segments of the Arava and EvronaF [ Zak and Freund , ; Garfunkel , ; Ginat et al ., ; Klinger et al ., , ; Niemi et al ., ; Makovsky et al ., ; Le Béon et al ., , ]. Geodetic estimates of the current horizontal plate motion across the DST are in the range of 3.7 to 7.5 mm/yr [ Wdowinski et al ., 2004; Mahmoud et al ., 2005; Ostrovsky , 2005; Gomez et al ., ; Le Béon et al ., ; Al Tarazi et al ., ; Sadeh et al ., ] and are in agreement with the geological rates.…”

“…North of the GEA, the DST passes along the Arava (Wadi 'Arabah) Valley. Mapping of offset surface features, aided by field observations, aerial photo analysis, and paleoseismic trenches [e.g., Zak and Freund , ; Garfunkel et al ., ; Ginat et al ., ; Klinger et al ., , ; Niemi et al ., ; Le Béon et al ., , ] and recent gravimetric and magnetic studies [ Haberland et al ., ; ten Brink et al ., ] revealed that the DST traverses the central Arava Valley predominantly as a single, almost continuous, sinistral strike‐slip fault. Modeling of gravity and magnetic data [ ten Brink et al ., , ], and seismic profiles [ Frieslander , ] revealed separate longitudinal basins along the Arava Valley.…”

Quaternary tectonic evolution of the Northern Gulf of Elat/Aqaba along the Dead Sea Transform

et al. 2014

The northern Gulf of Elat/Aqaba is located in the transition between the deep marine basins of the gulf and the shallow onland basins of the Arava Valley. Interpretation of 500 km of high-resolution seismic reflection data collected across the northern shelf reveals the tectonic structure and evolution of this transition. Six NNE-trending faults and one E-W trending transverse fault are mapped. Slip rates are calculated based on measured offsets and age determination based on a radiocarbon-calibrated sedimentation rate and a Quaternary age model. The most active fault is the Evrona Fault that absorbs most of the left lateral slip within the basin with an average sinistral slip rate of 0.7 ± 0.3 mm/yr through the Late Pleistocene and 2.3-3.4 mm/yr during the Holocene. Two intrabasin faults east of the Evrona Fault that have been inactive for the last several tens of thousands of years were mapped, and motion from these faults has likely transferred to the Evrona Fault. The basin is flanked on the west by the Elat Fault and on the east by the Aqaba Fault. Both faults are marked by large bathymetric escarpments. Based on displaced seismic reflectors, we calculate a Holocene vertical slip rate of 1.0 ± 0.2 and 0.4 ± 0.1 mm/yr for the Elat and Aqaba Faults, respectively. The geometry, slip rates, and slip history of the northern Gulf of Elat/Aqaba faults show that during the Late Pleistocene several intrabasin faults became dominant across the basin but that during the Holocene the Evrona Fault accommodates most of the strike slip.

“…From a regional perspective, the extensive measurements presently available imply that the average slip rate of the main part of the Haiyuan fault is 7.0 ± 2.0 mm/year, with no evidence of Latest Quaternary secular variation (Figure a). Other studies have documented consistent slip rates over multiple time scales, as we have here (Blisniuk et al, ; Cowgill et al, ; Gold et al, ; Grove & Niemi, ; Le Beon et al, , ; Toké et al, ). In terms of lateral variation, excluding earlier studies of Zhang et al (), He et al (), and Yuan et al (), which lacked rigorous geochronological constraints, the horizontal slip rate along the Haiyuan fault appears to slightly decrease eastward from Jinqiang He section to that broken in the 1920 Haiyuan earthquake.…”

Well-constrained fault slip rates are important for understanding strain partitioning within a fault system and the associated seismic hazard. The Haiyuan fault is a significant active strike-slip fault in the northeast margin of the Tibetan Plateau with ongoing controversy over its late Pleistocene slip rate. Previous work by Lasserre et al. (1999) suggested a slip rate of 12 ± 4 mm/year, which is higher than recent geodetically determined rates on adjacent fault sections. We reanalyze and reevaluate the slip rates benefiting from new high-resolution airborne Light Detection and Ranging data at their two sites, located north of the Songshan village. Based on this data, we revise field-mapped offset constraints. At the Majia Wan site, we document a sinistral displacement of 130 ± 10 m of the crest and 93 ± 15 m of the base of T1/T2 terrace riser, respectively. At the Xuanma Wan site, the offset of T4/T1′ terrace riser is updated to be 68 +3 / −10 m. Combining new geochronology dates, we assess the abandonment age of T2 as 26.0 ± 4.5 ka and T1 as 9,445 ± 30 year. These data suggest a slip rate between 5.0 +1.5 / −1.1 and 8.9 +0.5 / −1.3 mm/year since~26 ka, based on the upper terrace and lower terrace reconstruction, respectively. Our reevaluation supports that apparent slip rate discrepancies in northern Tibet possibly share a systematic bias due to the use of lower-terrace reconstruction to interpret the age of offset. Key Points:• Slip rate of the Haiyuan fault near longitude 37°is determined to be between 5.0 and 8.9 mm/year over the last~26 ka • Lower bound in geologic slip rate is similar to geodetic strain rate Supporting Information:• Supporting Information S1• Data Set S1

“…CRN dating is nowadays commonly used to infer the ages of alluvial terraces from surface and subsurface samples in a wide range of tectonic and climatic contexts (e.g., Anderson et al, ; Balco et al, ; Delmas et al, ; Gold et al, ; Gosse & Phillips, ; Guilbaud et al, ; Hancock et al, ; Hetzel, ; Lal, ; Le Béon et al, , ; Meriaux et al, ; Perrineau et al, ; Repka et al, ; Saint‐Carlier et al, ; Van der Woerd et al, , ; Yang et al, ; Yang et al, ). At Site S1, we collected quartz‐rich pebbles and cobbles from the terrace surfaces and amalgamated quartz‐rich gravel samples along depth profiles in 2‐ to 3‐m‐deep pits dug within the terraces to measure the concentration of 10 Be and 26 Al.…”

Late Pleistocene‐Holocene Slip Rate Along the Hasi Shan Restraining Bend of the Haiyuan Fault: Implication for Faulting Dynamics of a Complex Fault System

et al. 2019

The Haiyuan fault is a major left-lateral strike-slip fault at the boundary between northeast Tibet and the Gobi platform. Combining measurements of offset alluvial terraces with 10 Be-26 Al cosmogenic radionuclides dating, we bracket the late Quaternary slip rate along the Hasi Shan fault section (37°00′N, 104°25′E) of the Haiyuan fault. At our reference site, terrace-riser offsets for five successive terraces range from~5 to~200 m, and associated cosmogenic radionuclide ages range from 9 ± 3 to 44 ± 7 kyr. These measurements yield a geological slip rate between 2.7 and 3.0 mm/year. Extending the offset measurements to the entire Hasi Shan front, it yields a slip rate of 3.2 ± 0.2 mm/year over the last 50 kyr. Our rate is consistent with the lower estimates of other long-term rates of 4 to 5 mm/year, as well as with geodetic rates of 3 to 5 mm/year, determined in the same area. About 150 km farther west, however, Holocene terraces and moraines offsets have suggested higher slip rate values, between 6 and 15 mm/year. We interpret such discrepancy between rates determined along the western section of the Haiyuan fault and rates determined in the Hasi Shan section as being related to the complex geometry of the Haiyuan fault system along its eastern part, with several active strands moving at the same time and resulting in distributed slip among several sections of the fault system. Key Points: • Slip rate along the Hasi Shan section of the Haiyuan fault is determined from numerous offsets and cosmogenic exposure dates over a period of 50,000 years • The Hasi Shan fault strand horizontal slip rate is about 3.2 mm/year; this rate is stable over 50,000 years; the uplift rate is about 0.5 mm/year • Combining slip rate for the Hasi Shan strand and all subparallel stands yields a slip rate of 5 to 7 mm/year for the Haiyuan fault system Supporting Information: • Supporting Information S1
