Geometric-kinematic characteristics of the main faults in the W-SW of the Lut Block (SE Iran)

Strain rate and stress fields in the West and South Lut block, Iran: Insights from the inversion of focal mechanism and geodetic data

“…The results show a good correlation between the direction of the principal components of FMSI, SSR, and GSR. Our new analysis in the west and south of the Lut block were compared with the mechanism of the main faults which have been represented by the previous studies (Walker et al, 2010;Allen et al, 2011;Fattahi et al, 2011;Foroutan et al, 2014 andRashidi Boshrabadi et al, 2018).…”

“…In some triangles such as 8 and 9, the amount of horizontal extension rate is maximum where the main faults are the Gowk, Rayen and Mahan (Fig. 1c) in which the slip rate accumulation occurs (Rashidi Boshrabadi et al, 2018). Moreover, in triangles 11 and 12 near to the transitional zone between the Zagros, Central Iran and Makran, the horizontal extension rate has high values.…”

“…As such, different slip rates have caused a different level of seismicity in different parts of the area. Some studies have suggested a few numbers of new faults in the South and West of the Lut block (Rashidi Boshrabadi et al, 2018) in which we have used in this study. We analyze the relationships between strain rates, rotation rates and their directions with the mechanism of the old and new faults.…”

“…The Sabzevaran fault has a maximum slip rate of 5.7 ± 1.7 mm/yr (Regard et al, 2006). Since a part of the deformation is accommodated by the numerous thrusts in the western compartment (Rashidi Boshrabadi et al, 2018), so the overall strike-slip motion accommodated by the Nayband-Gowk system is decreasing from the South to the North. The obtained stress regimes and the compression stress direction, in the different parts of the study area (Table 3 & Fig.…”

The hydrogeochemistry of shallow groundwater from Lut Desert, Iran: The hottest place on Earth

“…The Lut Desert is within the Lut Block, whose basement consists of pre-Jurassic metamorphic rocks (pelitic schist) as well as Jurassic sediments intruded by younger (Jurassic to Tertiary) granitic plutons and covered by Tertiary mafic to felsic volcanics (Arjmandzadeh and Santos, 2014;Tirrul et al, 1983;Yazdi et al, 2014). The region is active tectonically with many active faults (Boshrabadi et al, 2018).…”
