An overview of the sedimentary geology of the Bengal Basin in relation to the regional tectonic framework and basin-fill history
TL;DR: The basin-fill history of these geo-tectonic provinces varied considerably as mentioned in this paper due to the location of the basin at the juncture of three interacting plates, viz., the Indian, Burma and Tibetan (Eurasian) Plates.

The detrital record of orogenesis: A review of approaches and techniques used in the Himalayan sedimentary basins
TL;DR: Using the sediment record to document tectonism is a well established approach, but more recently there has been a burgeoning of the number of isotopic techniques which can be applied to detrital material, in particular single-grain analyses.

Yani Najman,Mike J. Bickle,Marcelle K. BouDagher-Fadel,Andrew Carter,Eduardo Garzanti,Maxence Paul,Jan R. Wijbrans,E. Willett,Grahame J.H. Oliver,R. R. Parrish,Syed Humayun Akhter,Ruth Allen,Sergio Andò,E. Chisty,Laurie Reisberg,Giovanni Vezzoli +15 more
TL;DR: In this paper, the first major input of sands into the basin, in the > 1 km thick deltaic Barail Formation, occurred at 38 Ma, providing a well dated accessible sediment record 17 Myr older than the previously described 21 Ma sediments.

Miocene rise of the Shillong Plateau and the beginning of the end for the Eastern Himalaya
Marin K. Clark,Roger Bilham +1 more
TL;DR: In this paper, the authors suggest that the formation of the Shillong Plateau may be linked to a number of kinematic changes within the Himalayan and Burman collision zones that occur at the same time.
Journal ArticleDOI
Geology and depositional history of Cenozoic sediments of the Bengal Basin of Bangladesh
TL;DR: The basin structure and sedimentation were both strongly influenced by the collision pattern of the plates and by the uplift of the Himalayas as mentioned in this paper, which resulted in a rapid switch in sedimentation pattern in the Bengal Basin.

The Tectonic Framework of Assam
TL;DR: The Shillong Plateau is separated from the Surma Valley by a faulted monocline with southerly dips as discussed by the authors, which is known as the Dauki tear-fault.
Journal ArticleDOI
Cretaceous—Eocene sedimentation, tectonism and biofacies in the bengal basin, India
TL;DR: In this paper, an analysis of the sedimentary and tectonic history and bio-facies of the regions forming the western and northwestern shelves of the Bengal Basin pertaining to the initial phase of its evolution is attempted.
Journal ArticleDOI
Stratigraphy of Barail Series in Southern Part of Shillong Plateau, Assam, India: GEOLOGICAL NOTES
TL;DR: The Barail series (Oligocene), which includes the major petroleum reservoir rocks of India, has generally been considered to be absent in the southern part of the Shillong plateau Palynologic investigations of samples from the Tertiary section exposed in the Simsang river region and elsewhere along the south margin of the plateau indicate that biostratigraphic equivalents of the Barail beds are included in the mainly arenaceous rocks overlying beds of the Kopili stage.

H. M. Sale,P. Evans +1 more
TL;DR: Stratigraphy and structure of the Tertiary formations, geologic history, and the oil and gas occurrences of the region are discussed in this paper, with a focus on the extraction of natural gas.
