Q2. What is the tectonic tilt of the Dalrymple Trough?
Considering a steady India-Arabia motion of 3±1 mm.yr-1 (Fournier et al. 2008a,b; 2011), the Dalrymple Trough opened in response to a limited amount of strike-slip motion, in the order of 5-10 km.
Q3. What is the earliest evidence of a structural reorganization of the Makran wedge?
The critical Coulomb wedge theory and geological studies (Berger et al., 2008; Whipple, 2009; Malavieille, 2010; Iaffaldano et al., 2011) suggest that major climate changes can affect the wedge taper at a regional scale, and induce widespread structural reorganization.
Q4. Why is the Dalrymple Trough considered as transtensive?
Because the Dalrymple Trough deviates from the small circle defined by Fournier et al. (2011) (Fig. 2), the structure is considered as transtensive, in agreement with focal mechanisms of earthquakes.
Q5. What is the onset of contourite deposition at the southern Owen Ridge?
the onset of contourite deposition may reflect local disturbance of bottom currents following the opening of the basin (Rodriguez et al., 2013b).
Q6. What is the age of abandonment of the youngest channel-levee?
The age of abandonment of the youngest channel-levee is estimated by the thickness of the overlying pelagic cover, converted into time using uniform pelagic sedimentation rates in the area (30-55 m Ma -1 ).
Q7. What is the last structural reorganization of the Makran wedge?
The last structural reorganization marked by the M-unconformity is roughly coeval with the opening of the Dead Sea Basin along the Levant Fault (TenBrink et al., 1989).
