Chota Nagpur Plateau has the remains of an old fort belonging to the Nagavanshis. The Chhota Nagpur Plateau is a continental plateau—an extensive area of land thrust above the general land. The plateau has been formed by continental uplift from forces acting deep inside the earth. The Gondwana substrates attest to the plateau's ancient origin. It is part of the Deccan Plate, which broke free from the southern continent during the Cretaceous to embark on a 50-million-year journey that was violently interrupted by the northern Eurasian continent. The northeastern part of the Deccan Plateau, where this ecoregion sits, was the first area of
Plateau de Millevaches large lens-shaped mass of granite, believed to be the result of an intrusion of igneous material in the late Hercynian or Variscan orogeny. As the surrounding, softer material has weathered away, the laccolith has become increasingly exposed. Although not strictly a plateau, depending upon which direction one approaches the area from, the Plateau de Millevaches forms an important kind of step up (or a step down) in the Massif Central. There are a number of definite peaks, the highest being Mont Bessou (976m.), at the southern edge of the massif, near Meymac. The massif is generally densely wooded, with large
