Arabian Basin

Early Jurassic breakup of Gondwana (left) and A- Early Cretaceous, B- Late Cretaceous, C-Paleocene, D- Present Day (right)

The Arabian Basin is an oceanic basin located in the southern part of the Arabian Sea between the Arabian Peninsula and India. It is centered at 10° N, 65° E.[1] The basin depth ranges from 3,400 m in the north to 4,400 m in the south, with a maximum depth of 4,652 m.[1] The floor is covered by sediments from the Indus submarine fan and is relatively smooth.[2]

The southern enclosure of this basin is formed by the Central Indian Ridge, the Carlsberg Ridge and the Chagos-Laccadive Ridge. Bottom water enters the basin through the Owen fracture zone to the west.[3] The Carlsberg Ridge, at a depth of 3,800 m, separates this basin from the Somali Basin to the southwest.[1] The Arabian Basin is separated from the shallow Oman Basin by the Murray Ridge.[4] Most of the northern and eastern limits are formed by the Laxmi Ridge and the Laccadive Plateau.[2]
