Abstract:
Grain size study carried out on a small sheltered black sand beach, reveals that the sediments are moderately well sorted and mostly negativegly skewed with mean size falling within coarse to very coarse sand class. The weight percentage of heavy minerals obtained vary from 28.76 to 42.8% between size fractions 2.75 theta and 4 theta. The heavy minerals identified includes hornblende, tremolite, magnetite, ilmenite, pyroxenes and epidote. The results obtained are used to explain energy conditions and also provenance.
