Mineral deposits
Several minerals are found in the coastal corridor namely beach sand, heavy mineral deposits such as Ilmenite, Leucoxene, Monazite etc. An estimate of 241 million tonnes of deposits of mineral reserves are present in the beach sand of the state coast.[5] Silica sand reserves are found along the coastal areas of Prakasam, Nellore and Guntur districts. Silica sand are used for Moulding sand, Sodium silicate, Ceramic, glass etc. Quartzites are found in Orvakal of Kurnool district.[6]
