Abstract

Red sediments are of a unique feature that exists in the east coast near Visakhapatnam. The Origin has been debated for over the years, most accepted is formed by the denudational remnants of a great sandbank of Pliocene times or isolated banks formed around sunken hills. Red sediments are formed by the cumulative work of wind and running water, where the red colour pigment is being preserved by the digenetic breakdown of iron-bearing minerals. Iron oxides derived from the red soils in the sources area (Khondalite terrain). Favorable environmental conditions for the preservation of the pigment in the depositional basin. The colour of the red sediments is mostly moderate reddish brown and moderate red. Moderate yellowish brown and dark reddish brown sediments are occurring in certain parts of Visakhapatnam region. The upland soils are pale reddish brown to moderate reddish brown. Many geomorphic features are observed like gullies, buried channels, Lineaments, beach ridges, sand dunes, wave-cut terrace, knick points and waterfalls, yellow sand unit, reddish-brown concretion bearing sand unit, brick-red sand unit, light yellow sand unit, duricrust, and pebble beds. Textural analysis has been made in these areas; results show that these are originated from under fluvial environment.
