Erra Matti Dibbalu-Geoheritage sites

Erra Matti Dibbalu

Erra Matti Dibbalu is dissected and stabilized coastal red sediment mounds, located between Visakhapatnam and Bheemunipatnam in Andhra Pradesh.

Formation:

  • Formed around 12,000 years ago due to sea-land interaction.
  • Comprises a mixture of sand (40-50%), silt and clay (another 50%) with oxidation imparting the unique red colour.

Significance:

  • They are geologically important as they represent the geological history of the late Quaternary period and carry the imprints of the fall of sea level and its subsequent rise, the impact of climate, monsoon and geological processes on the sediments.
  • They are anthropologically and archeologically important as they possibly contain mesolithic and neolithic cultural materials as well.

Recognition:

  • It was recognised as a national geo-heritage site in 2014 and as a protected site by the Andhra Pradesh Government in 2016.
  • The Geological Survey of India (GSI) declares geo-heritage sites/ national geological monuments for protection and maintenance
  • Other Similar Place: The only other place in the country to have a similar stretch of red sand dunes is Tamil Nadu, which has the Teri dune complex.
