Abstract: A unique thin ferruginous layer sandwiched between phosphatic sediments of the Fatehgarh Formation representing northern periphery of the Barmer basin, India. Magnetic separation of this layer yielded presence of magnetic glassy spherules of millimeter size. In the present investigation, Mössbauer and XRD study of twelve phosphatic sediments including ferruginous layer of Fatehgarh Formation was carried out. For the first time, a very unusual and complex pattern of Mössbauer parameters attributed to an unusual thermal history in late Cretaceous phosphatic sediments of the Barmer basin has been shown.
