The Itina Trough is a late Miocene rift graben formed at the beginning of Woodlark Basin opening where the northern Louisiade Plateau micro‐continent had collided with the eastern Pocklington Rise remnant arc. We infer that it was the collisional suture of this Plateau subducted at the Pocklington Trough that either thickened the crust and weakened the lithosphere and/or adjoined the apparently thicker Louisiade micro‐continent to the thinner crust of the eastern Pocklington Rise, and thereby localized the rifting. Other examples of rifting across a remnant arc‐trench system in the SW Pacific include the South Rennell Trough and the Norfolk Basin.

Itina Trough和其他西南太平洋跨越前俯冲/碰撞带的例子

伊蒂娜海槽是在伍德拉克盆地开放开始时形成的中新世晚期裂谷，那里的北部路易斯安娜德高原微大陆与东部的波克林顿崛起残余弧相撞。我们推断，是在Pocklington槽俯冲的高原的碰撞缝合线使地壳变厚并削弱了岩石圈，并且/或者使表面较厚的Louisiade微大陆与较薄的东Pocklington Rise地壳相接，从而将地壳局部化了。裂谷。裂谷的其他例子横跨在西南太平洋的残余弧沟系统包括南伦内尔海槽盆地诺福克。
