A guide to rapid identification of heavy minerals and highlights of heavy mineral distribution pattern along Indian coasts

摘要

The economic potential of heavy mineralsis very important .and has been discussed by a number of workers. The Heavy mineralsare very helpful for provenance studies and have been used for correlation of stratigraphicunits. Detail studies of some heavy minerals help in understanding thetransport history and give a clue to processes and environment of deposition.Morphological character and colour of Heavy minerals has sometimes been used tolocate the source rocks more categorically. The distribution pattern andmineral assemblages can also help in understanding the transport and directionof dispersal, the geomorphologic changes, tectonic implication, environmentaldiscrimination, and depositional history. Modern generation scientists areallergenic to identification of heavy mineral grains under microscope. It isstill used in some cases as a tool to corroborate with research findings. Thisimportant field is being neglected because of proper identification. In thispaper attempt is being made to give a guide line for rapid identificationgiving different steps from detailed studies around Indian Coasts.
