The limestone resources of Hawaii are derived chiefly from emerged fringing coral reef and coastal dune deposits of Pleistocene age. These deposits are most abun¬dant on the island of Oahu and other older islands and least abundant on the island of Hawaii, the youngest. Their origin and depositional environment were influenced by glacio-eustatic rising and falling of sea levels during Pleis¬tocene time. Dredged reef limestone deposits from two deep-water harbor projects have provided additional re¬sources. Limestone uses include cement and lime manufac¬turing, concrete sand and aggregate, road base material, beach sand replenishment, agricultural lime, and golf course construction.
