dc.description.abstract The western shelf of India is characterisEd. by the presence of Recent clayey sediments on the inner shelf and relict carbonate sediments and a variety of limestones on the outer shelf. The limestones of the outer continental shelf between 60 and 150 m water depth were studied for their petrology and to evaluate the palaeoclimatic conditions during Quaternary. The limestones characteristic of abundant microspar and pseudospar are found at water depths 65 and 95 m, respectively on the continental shelf off Ratnagiri. They also consist of marine fauna. These are neomorphic limestones which evidence the Pleistocene high sea levels on the shelf. Caliche pisolites recovered at 60 m depth off Goa indicate continental conditions associated with arid climate and low rainfall during Late Pleistocene. The occurrence of neomorphic limestones and caliche pisolites on the shelf implies varied climatic conditions within the Pleistocene
