It is closed in the south by the West Australian Range , in the west by the East Indian Ridge , in the north by a chain of seamounts between the Cocos Islands and Christmas , in the east by the mainland slope of Australia .
The dissected hilly bottom topography prevails. The depth is 5,000–6,500 m, and on separate uplifts it falls to 1,500 m. Near Australia there are large mountain ranges, which are, apparently, the remains of ancient continental structures. The bottom soils are composed of red clay , radiolaria and foraminifera silts . Widely developed iron - manganese nodules; on tops of mountains and hills - outcrops of bedrock.
