Journal of Sedimentary Research (1985) 55 (3): 392–397.
...A. Chaudhuri; James D. Howard Abstract Much of the abundant Precambrian sedimentary record of India appears to have been deposited in shallow coastal environments. One example of this, the Ramgundam Sandstone, is a moderately thick (120 m) unit composed of lens-shaped bodies of arkosic sandstone...

... of the age spectra distinguishes between ages that are interpreted to reflect the time of glauconite formation, and anomalous ages that result from inherited argon or postcrystallization heating. The analyses indicate an age of 1686 ± 6 Ma for the Pandikunta Limestone and 1566 ± 6 Ma for the Ramgundam...

... from a thick limestone of possible lagoonal origin. Close relation of sedimentary lithofacies and morphotypes of the biogenic structures and their stratigraphic zonation is clearly demonstrated in Ramgundam (79°26′E, 18°45′N) and Somanpalli (80°15′E, 18°46′N). Observations in other parts of the valley...

... of glauconitized sandstones indicate that glauconite formed in varying conditions of turbulence and bathymetry. A glauconitic layer in Ramgundam (18°45′N, 79°26′E) appears to have formed in a quiet environment, at moderate depth below wave base, during brief periods of transgression. Large bed forms in a thick...

.... It overlies the cycle I sediments with a major unconformity and passes on to the shoaling-up tidal bars of the Ramgundam Formation. The aggradation was controlled by a fluctuating balance between the rate of sediment supply and creation of accommodation space at the basin margin. The facies association...
