Origin Of Mineral Sands Deposits

Apr 01 2018 Heavy mineral deposits are unconsolidated detritus sediments that accumulate in coastal environments both on beach and coastal sand dunes. These deposits derive from the weathering of pre-existing rocks of mainly high-grade metamorphic and igneous origin.
