The Barmer basin in Rajasthan (India) is a narrow, failed, continental rift basin with uplifted rift shoulders exposed along its E and W margins. The basin trends NNW and comprises of thick Mesozoic and Tertiary sediments. Its tectonic evolution is somewhat linked to other Mesozoic and/or Tertiary basins of NW segment of Rajasthan, India. The Barmer basin comprises of thick sedimentary sequence from Jurassic to recent overlying the Malani Igneous Suite. Structural field studies (Dasgupta and Mukherjee, 2017) along the rift margins helped in deciphering the two-phases (NW-SE followed by NE-SW) of extension through brittle shear tectonics. Field studies further identified: (1) structural inheritance of NNW trending fractures of older Malani basement rocks in the NW trending rift faults, (2) role of transfer zones (Dasgupta and Mukherjee 2019, Dasgupta and Maitra 2018, Dasgupta 2018) in rift fault propagation. Near NE trending mega-scale transfer zones have been documented along the Fatehgarh fault trend in N margin of the Barmer basin. See Bladon et al. (2015), Dolson et al. (2015), Dasgupta and Mukherjee (2017), Dasgupta and Mukherjee (2019) and Sharma (2007). for recent understanding on the tectonic of the Barmer region and its surroundings.
