Coastal placer mineral evaluation using GIS approach : a case study at Kallar Vembar coast
Rajamanickam, M. ... [et al]
The deposits along the coastline between Kallar and Vembar are well-disposed long continuous beaches throughout the coastline. The shorelines of these areas have been experiencing both accretion and erosion. The beaches have enriched with economic minerals such as ilmenite, garnet and zircon. In the present study focused on Beach Placer mineral deposits along the beach profile represented three dimensional perspectives views. More over, the studies of grain size, heavy minerals and beach profile variation have led to evaluate the placer potentiality in this region. The integration of mapping and database through Arc GIS allows us to identify and analyse the possible correlation between the variables of heavy mineral placers in that location. Data of beach profile, grain size and heavy mineral values are displayed in the form of polygon and buffer to show the relationship among them.
