    Abstract
    Heavy mineral studies were undertaken systematically along the coastal region from Poompuhar to Nagoor, Tamil Nadu, India. Heavy mineral studies by different size grades show a similar trend of concentration from +70 to +200 mesh except +80 and +170 mesh size grades. After the tsunami, the modality is shifted to a slight coarser grade in all the beaches in such a way an enrichment of concentration is noticed in 50 mesh size grade also. In the Total heavy mineral by wt %, shows that post-tsunami samples Chinnankudi an upshoot of heavies to a tune of 93% in the Berm of Nagoor and HT of Chinnankudi. At Poompuhar, the distributions of heavy minerals are found to be different to other two stations. While Poompuhar establishes overall rise in the Wt % of heavy minerals during Post Tsunami like other stations, from Dec. 2003 to Dec. 2004 unlike other stations, it is not giving any higher percentage in LT and Berm samples. Chinnankudi maintains always a higher percentage in LT, HT and Berm too, except post tsunami conditions when compared to Nagoor. When the distribution of heavy minerals in LT, HT and Berm is considered station wise during the years 2003, 2004 and 2005. Poompuhar is seemed to behave different to others. The heavy mineral enrichment increases from North (Poompuhar) to the South (Nagoor) in the study area. The same may be attributed to the inner shelf gradient.
