Receiver function modeling at 15 broadband stations in eastern Indian shield is done.
A relatively thicker crust of 43 ± 3 km characterizes the Archean Singhbhum craton.
A thin crust of 38 ± 1 km characterizes the younger Eastern Ghats mobile belt.
A stable Proterozoic cratonic crust of 41 ± 1 km is noticed underlying the CGGT.
Our study could not detect any age dependent variation of crustal thicknesses.
