Abstract
In the absence of definite evidence, no consensus exists regarding the origin of Ramgarh structure (N 25°20': E 76°37') located in the Baran district of Rajasthan, India. A detailed survey of the structure was therefore undertaken during which we found impact spherules, diaplectic glasses and observed planar deformation features in quartz grains. These observations are indicative of impact since they require high pressure-temperature of 30-50 GPa, which is generally produced due to shock and not normally encountered in terrestrial processes such as volcanism and compression due to tectonic forces.
