由于阿尔沃兰盆地的一部分已经露出，阿尔沃兰基底中是否存在伸展拆离断层可以直接检验。这些与阿尔沃兰盆地下地壳减薄有关的构造活动发生在阿奎坦阶至托顿阶。由此产生的拉伸几何形状可以用一般术语来描述。在塞拉瓦利期，海盆向西南方向扩展，同时北方直布罗陀弧向东南方向扩展。其他受塞拉瓦利亚扩张影响的地区也可以找到。阿尔沃兰的扩张几乎与直布罗陀山前向西迁移的时间相同。
Whether or not there are extensional detachment faults in the Alboran basement can be tested directly because a part of the Alboran Basin is now emerged. These detachments, related to crustal thinning beneath the Alboran Basin, occurred from the Aquitanian to Tortonian. The resulting extensional geometries can be described in general terms. During the Serravalian a considerable southwest extension of the basin took place, accompanied by south-southeast extension in the northern Gibraltar Arc. Other detachments affected by Serravalian extension can be found. The spreading of the Alboran was nearly coeval with roughly westward migration of the Gibraltar mountain front.
