Nias Basin (original) (raw)
The Nias Basin (also known as the West Sumatra or Sibolga Basin) is a forearc basin located off the western coast of Sumatra, Indonesia, in the Indian Ocean. The name is derived from the island that bounds its western edge, the island of Nias. The Nias Basin, the island of Nias (which is a subaerial part of the accretionary complex), and the offshore, submarine accretionary complex, together form a Forearc region on the Sunda Plate/Indo-Australian Plate collisional/subduction boundary. The Forearc region is the area between an oceanic trench and its associated volcanic arc. The oceanic trench associated with the Nias Basin is the Sunda Trench, and the associated volcanic arc is the Sunda Arc.

| dbo:abstract | The Nias Basin (also known as the West Sumatra or Sibolga Basin) is a forearc basin located off the western coast of Sumatra, Indonesia, in the Indian Ocean. The name is derived from the island that bounds its western edge, the island of Nias. The Nias Basin, the island of Nias (which is a subaerial part of the accretionary complex), and the offshore, submarine accretionary complex, together form a Forearc region on the Sunda Plate/Indo-Australian Plate collisional/subduction boundary. The Forearc region is the area between an oceanic trench and its associated volcanic arc. The oceanic trench associated with the Nias Basin is the Sunda Trench, and the associated volcanic arc is the Sunda Arc. The Nias Basin itself is structurally bounded to the west by the and bounded to the east by the Volcanic Arc island of Sumatra. It is a geologically independent basin from its neighbor basins; the to the north, and the to the south. The Nias Basin spans ~250 kilometer length-wise, and ~100 kilometers width-wise. Overall, the Nias Basin can be divided into two sub-basins; the Singkel Basin to the north, and the Pini Basin to the south. These basins are distinguished by their independent development during the early formation of the primary basin, but later consolidated when subsidence of the area was more unified over the whole Nias Basin region. (en) Cekungan Nias (juga dikenal dengan nama Cekungan Sumatra Barat atau Cekungan Sibolga) adalah cekungan busur muka yang terletak di lepas pantai barat Sumatra, Indonesia, di Samudra Hindia. Namanya berasal dari nama pulau yang berbatasan dengan sisi baratnya, pulau Nias. Cekungan Nias, pulau Nias ( darat), dan perairannya, bawah laut, membentuk busur muka di perbatasan tubrukan/subduksi Lempeng Sunda/Lempeng Indo-Australia. Busur muka terletak di antara palung samudra dan busur vulkaniknya. Palung samudra dan busur vulkanik yang bersambung dengan Cekungan Nias adalah Palung Sunda dan Busur Sunda. Cekungan Nias berbatasan dengan Sesar Mentawai di barat dan busur vulkanik pulau Sumatra di timur. Secara geologi, cekungan ini terpisah dari cekungan-cekungan tetangganya, di utara dan di selatan. Cekungan Nias membentang sepanjang ~250 kilometer dan selebar ~100 kilometer. Secara keseluruhan, Cekungan Nias bisa dibagi lagi menjadi dua sub-cekungan, Cekungan Singkel di utara dan Cekungan Pini di selatan. Kedua cekungan ini terbentuk secara terpisah pada masa awal terbentuknya cekungan utama, kemudian menyatu ketika penurunan dasar laut terjadi di seluruh kawasan Cekungan Nias. (in) |
