Attempts have not been made by any to study heavy mineral assemblage of the Tertiary sediments exposed in the well sections around Ratnagiri, Maharashtra and therefore, the present investi­gations are envisaged to make the assessment by carrying out the systematic heavy mineral studies.  About 15 sediment samples were analyzed for heavy mineral separation.  The results bring out the predominant distribution of opaques, zircon, tourmaline, rutile, anatase, amphibole and pyroxene. From the heavy minerals content of the Tertiary sediments, following observations have been brought out.

1) Pyroxenes are present in all the samples, while, very few samples show the presence of amphiboles. 2) Nearly even distribution of anatase has been noticed in all the samples. 3) Euhedral grains of tourmaline are present in most of the samples, whereas, zircon occurs in uneven distribution throughout the area. 4) Nodular grains of pyrite are found to be abundant mainly in the samples from the western border of the area. 5) Grains of magnetite, hematite with ilmenite are present in grey shale, associated with laterites.
