The Eastern Ghats or Pūrva Ghaṭ, also known as Mahendra Pravata, are a discontinuous range of mountains along India's eastern coast. The Eastern Ghats run from West Bengal state in the north, through Odisha and Andhra Pradesh to Tamil Nadu in the south passing some parts of Karnataka. They are eroded and cut through by the four major rivers of peninsular India, known as the Godavari, Mahanadi, Krishna, and Kaveri. The mountain ranges run parallel to the Bay of Bengal. The Deccan Plateau lies to the west of the range, between the Eastern Ghats and Western Ghats. The coastal plains, including the Coromandel Coast region, lie between the Eastern Ghats and the Bay of Bengal. The Eastern Ghats are not as high as the Western Ghats. ==Geography== The Eastern Ghats are older than the Western Ghats, and have a complex geologic history related to the assembly and breakup of the ancient supercontinent of Rodinia and the assembly of the Gondwana supercontinent. The Eastern Ghats are made up of charnockites, granite gneiss, khondalites, metamorphic gneisses and quartzite rock formations. The structure of the Eastern Ghats includes thrusts and strike-slip faults〔(''Geology of Eastern Ghats in Andhra Pradesh'' - Springer ). Link.springer.com (1967-11-01).

The Eparchaean Unconformity of the Tirumala Hills is a major discontinuity of stratigraphic significance that represents an extensive period of erosion and non-deposition. It is seen at the steep natural slopes, road scars and ravines in the Tirupati – Tirumala Ghat road in the Chittoor district of Andhra Pradesh.〔(【引用サイトリンク】 title= Eparchaean Unconformity, Tirumala Ghat section )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern Ghats」の詳細全文を読む スポンサード リンク
