Morphometric dataset of the alluvial fans at the southern part of Nayband fault, Iran

Abstract

This data article provides a precise level data on alluvial fans of the western border of Lut desert, a unique location on the Earth, known as one of the hottest spot on the Earth. This data is essential for morphotectonic investigations and is valuable in the field of tectonic and geomorphology studies. It helps to evaluate the region from the viewpoint of tectonic activity by considering the dynamics of alluvial fans, climate and tectonic setting. The data which are presented for 68 quaternary alluvial fans, is taken by processing of remotely sensed Landsat satellite data, photogeology of aerial photographs, measuring on topographic maps and controlled by field checking. This data is useful for defining of a morphotectonic model of this limited access region considering the uplift of the source area along Nayband fault, as the basin–margin fault, respect to the base level.

Strain and Moment Rates from GPS and Seismological Data in Northern Iran: Implications for an Evaluation of Stress Trajectories and Probabilistic Fault Rupture Hazard

“…This ratio in the study area with ~0.23 × 10 6 km 2 area is 70.7 which can be compared with the results of the previous studies in the United States [1], Basin and Range [2], the west and south Lut block [3]., and the east and north Lut block [4] (Table 11). The seismic/geodetic moment rate in the area is higher than that of the Basin and Range and the west-south Lut Block where morphotectonic studies emphasize its activity [104][105][106]. The obtained results indicate the Alborz (networks 7, 8, 9, 17, 10, 18, 11, and 12), western Koppeh-Dagh (networks 5, 13), northern part of Central Iran (networks 14, 15, 16, 19, 20, and 21), South Caspian Sea (networks 2, 3, and 4), and Talesh (networks 1 and 6) had, respectively, a portion of 0.9, 0.3, 11.9, 0.3, and 57.3 of the seismic/geodetic moment rates, which shows much of the elastic energy has been released in the Talesh and northern part of Central Iran.…”

The seismic/geodetic moment rate in the area is higher than that of the Basin and Range and the west-south Lut Block where morphotectonic studies emphasize its activity [104][105][106] The ratio of seismic to geodetic moment rate denotes low values for networks 16, 4, 13, 9, and 19, and high values for networks 6, 15, 20, 1, and 17. Network 6 is characterized by higher released energy, which can be interpreted as due to the active faults interaction in the Talesh-Alborz transfer zone.…”

Predicting Fault Locations based on Morphometric Features of Alluvial Fans and Basins using Artificial Neural Networks

“…Therefore, the morphometric characteristics of alluvial fans can be used to determine tectonic activity in an area Hashemi et al 2018;Yamani et al 2012).…”

Flexural-slip folding in buckling phases of orogenic belts: Insight into the tectonic evolution of fault splays in the East Iran orogen

“…This orogenic belt which is located between the Afghan block in the east and sub-zones of Central Iran (e.g., the Lut block) in the west includes the fastest-slipping faults in eastern Iran (Figure 1B) (Walker and Khatib, 2006;Mehrabi et al, 2021;Rashidi et al, 2021). The Nehbandan (West Neh and East Neh branches), Nosrat-Abad and Kahourak faults within the East Iran orogen constitute the eastern boundary of the Lut block, and the Sabzevaran, Gowk, and Nayband faults determine the western boundary of the Lut block (Figure 1B) (Hashemi et al, 2018;Rashidi et al, 2020). These active faults are laterally slipping at a rate of 5.6 ± 0.6 mm/yr and 4.4 ± 0.4 mm/yr, respectively (Walpersdorf et al, 2014).…”
