Laterite in Angadipuram, Malappuram district, Kerala

Economic Laterite in Angadipuram has been derived from acid charnockite. The crystalline rocks of this region are an admixture of pyroxene granulite, charnockite and migmatite. The laterite here occurs at an average elevation of 60 m above m.s.l. Laterite is significant from the economic angle since mineral deposits of aluminium ore (bauxite), iron ore and nickel ore are known to be associated with them. The monument is located about 16 km from Malappuram on the road to Palghat and lies on the Shoranur‐ Nilambur railway line. It is located within the premises of the PWD rest house.

Bedded Barytes of Mangampeta, Cuddapah district, Andhra Pradesh

Economic One of the largest baryte deposits of the world, is considered to have formed through precipitation from volcanic vapours under submarine conditions and sub aerial showering of ash and molten baryte lapilli. The deposit occurs in the Pullampet Formation of the Nallamalai Group of the Cuddapah Supergroup. The lower beds of Mangampeta Barytes are of the highest grade and often occur as pure barium sulphate. It has a reserve of over 74 million tonnes that constitutes about 98% and 28% of the total known reserve of India and the world respectively.

The Kurnool‐ Ranigunta state highway passes through the Mangampeta mines area. The nearest Railway station is about 10 km away at Koduru on the Kurnool‐ Tirupati line of the South Central Railway.

Gossan, Rajpura‐Dariba, Rajsamand District, Rajasthan

Economic This gossan led to rediscovery of Rajpura‐ Dariba mineralised zone. It has formed due to extensive chemical weathering and pervasive oxidation of the suplhides‐ sulphosalts ore bodies through prolonged geological periods under favourable climatic condition. The gossans show a variety of colours including reddish brown, brown, dark brown, bluish green, white and grey and also different type of boxworks. The chief ore minerals are sphalerite, galena and chalcopyrite. Zinc is the dominant base metal followed by lead and copper.

The gossan is located between Dariba and Rajpura villages in Rajsamand district over a length of 4.5 km with 2 to 40 m width and 15 km NNE of Fatehnagar Railway station on Chittor‐ Udaipur section of Western Railway.
