Occurrence of heavy minerals in the coastal sediments of Daman-Dandi, Gujarat

摘要

Reconnaissance survey for a preliminary appraisal of heavy mineral occurrence was carried out from Dandi in the north to Daman in the south along the coast of Gujarat. Forty-five samples collected from different geomorphic units like foreshore, berm and dune were subjected to grain size analysis and heavy mineral evaluation. The beach and dune sediments are predominantly carbonate-free sand except one sample collected at Tithal. The mineralogical composition of beach and dune sediments is found to be more or less similar. Ilmenite and magnetite are the major constituents. Rutile, sillimanite, zircon, etc. are present in minor quantity.
