Qualitative assessmentR6: Tract is unlikely to be developed based on the available data in the opinion of the assessors; very little positive information exists.
Tract delineationThe Nagaur tract consists of an area underlain by Neoproterozoic potash-bearing salt and salt structures as determined using the geologic maps of Pakistan (Qureshi and others, 1993) and Rajasthan (Kumar and Chandra, 2005) in conjunction with a generalized diagram showing the distribution of the salt (Kumar and Bakliwal, 2005).
