The range and complexity of basement rocks at Eppawala are accompanied by complex matrices of phosphate deposits. Thorough field, geochemical and mineralogical reports had been carried out on phosphatic weathering crusts designed on carbonatite occurrences to elucidate the weathering process also to check out mineralization of achievable financial minerals. The presence of markedly distinguished weathering horizons within the Eppawala southern quarry (ES) web-site delivered a bonus for finding out the sequence of alteration and weathering procedures occurred about the dad or mum bodies. Leaching of carbonate minerals within the early stages had resulted during the alteration of Major apatite.
