Granulometric and facies analysis of Middle–Upper Jurassic rocks of Ler Dome, Kachchh, western India: an attempt to reconstruct the depositional environment
Autor: M. A. Quasim, Sumit K. Ghosh, Asma A. Ghaznavi, A. H. M. Ahmad
Publikováno v: Geologos, Vol 25, Iss 1, Pp 51-73 (2019)
Grain size analysis is an important sedimentological tool used to unravel hydrodynamic conditions, mode of transportation and deposition of detrital sediments. For the present study, detailed grain size analysis was carried out in order to decipher t
