Deccan Lava Plateau - Deccan Trap

Japanese: デカン溶岩台地 - デカンようがんだいち（英語表記）Deccan Trap

The world's largest lava plateau, occupying the northwestern part of the Deccan Plateau. Approximately 65 million years ago, as the Indian subcontinent (present-day Indian peninsula) was moving north from the southern hemisphere, large amounts of basaltic lava repeatedly erupted from numerous vents. Today, the western half of the plateau has been lost, and the coast of the Arabian Sea has become a 1,000m cliff, with numerous flat cross-sections of lava flow layers exposed. Its total volume is over 700,000 ^km3 , covering an area of 500,000 km2, and stretching 1,500 km from east to west and 1,400 km from north to south. A single lava flow can be traced for over 200 km.

デカン高原の北西部を占める世界最大の溶岩台地。約6500万年前，インド亜大陸(現在のインド半島)が南半球から北へ移動中に，大量の玄武岩質溶岩が多数の噴出口からくりかえし噴出して生じた。現在はその西半分が失われ，アラビア海沿岸は1000mの崖となり，数多くの平たんな溶岩流層の断面が露出している。全体積は70万km³以上，広さ50万km2を覆い，東西1500km，南北1400km。1枚の溶岩流が200km以上にわたって追跡される。
