Paraná - Etendeka perangkap ( atau Paraná dan Etendeka Plateau , atau Paraná dan Etendeka Provinsi ) terdiri dari provinsi berapi besar yang meliputi perangkap Paraná utama ( di Paraná Basin , sebuah Amerika Selatan basin geologi ) serta bagian-bagian yang terpotong lebih kecil dari basal banjir di perangkap Etendeka ( di laut Namibia dan daya Angola ) . Arus basal asli terjadi 128-138000000 tahun yang lalu . Provinsi ini memiliki luas permukaan pasca - aliran 1,5 x 106 km² ( 580.000 miles² ) dan volume asli diproyeksikan untuk menjadi lebih dari 2,3 x 106 km³ . [ 1 ] [ 2 ]

Sampel basalt di Paraná dan Etendeka memiliki usia sekitar 132 Ma . [ 3 ] Secara tidak langsung, rifting dan ekstensi mungkin asal Paraná dan Etendeka perangkap dan itu bisa menjadi asal dari Kepulauan Gough dan Tristan da Cunha juga , karena mereka terhubung dengan ( hotspot Gough / Tristan ) Walvis Ridge . The gunung laut dari Rio Grande Naik ( 25 ° S 35 ° S ) pergi ke arah timur dari sisi Paraná [ 4 ] [ 5 ] dan pada tahun 2013 dinilai sebagai bagian dari sistem perangkap berikut pemulihan sampel . [ 6 ] Sumber yang masih belum jelas , namun, apakah situs ini telah menjadi subyek dari apa yang mungkin telah tunggal letusan gunung berapi terbesar ledakan dalam sejarah Bumi (lihat Daftar letusan gunung berapi terbesar ) .
