Description Owing to the limitations of the existing conventional methods for mapping subsurface sedimentary layers, Geophysical methods especially GPR (Ground Penetrating Radar) techniques are widely being used. For the present study, a 60 m long transect at Nagoor beach, Tamil Nadu, India has been traversed using GPR system (GSSI make SIR 20 system) with 200 Mhz and 400 Mhz antennae. A trail pit upto 1.25 m depth has been refereed for sampling and correlation purpose with GPR data. Several GPR profiles have been carried out along and across the trail pit with different gains. The GPR data signs agreement with the field observations (trail pit data) and appreciably correlating with the heavy mineral and white sand layers. Based on the significant signature of the heavy mineral layers, they could be traced all along the sub-surface profile. It is also seen that the graunlometric data on sorting, kurtosis and skewness have fairly agreement with the GPR data. More discussions have been enumerated in the paper, which warrants more such studies for the establishment of inter-relationship between the field geological parameters with the GPR sub-surface profiles.
