Abstract

The natural resources of the Andaman–Nicobar Islands and surrounding seas are discussed. Rocks and minerals found on the Andaman Islands include magnetite, pyrite-chalcopyrite, chromite, gold, nickel, sulphur, coal and limestone, but in most cases their concentrations are sub-economic. Lensoid bodies of algal-biohermal limestones of Palaeogene age on Middle Andaman Island are abundant, accessible and of good grade for cement or foundry work. The Neogene limestones are also suitable for this purpose. Basalts and strongly indurated sedimentary rocks, without any overburden, are quarried for construction work. Limited offshore exploration for oil and natural gas shows great promise, but has yet to be developed.
