Oblique collision of buoyant provinces against subduction zones frequently results in individualizing and rotating regional‐scale blocks. In contrast, the collision of the Bahamas Bank against the Northeastern Caribbean Plate increased the margin convexity triggering forearc fragmentation into small‐scale blocks. This deformation results in a prominent sequence of V‐shaped basins that widens trenchward separated by elevated spurs, in the Northern Lesser Antilles (NLA, i.e. Guadeloupe to Virgin Island). In absence of deep structure imaging, various competing models were proposed to account for this Basins‐and‐Spurs System. However, high‐resolution bathymetric and deep multichannel seismic data acquired during cruises ANTITHESIS1‐3, reveal a drastically different tectonic evolution of the NLA Forearc.

小安的列斯群岛北部的古近纪V型盆地和新近纪沉降

活跃省份与俯冲带的倾斜碰撞经常导致区域规模块的个体化和旋转。相反，巴哈马银行与东北加勒比板块的碰撞增加了边缘凸度，引发前臂破碎成小块。这种变形导致北部小安的列斯群岛（NLA，即瓜德罗普岛至维尔京群岛）的V形盆地的突出序列扩大了被高高的马刺隔开的沟渠。在没有深层结构成像的情况下，提出了各种竞争模型来解释该盆地和马刺系统。但是，在ANTITHESIS1-3航行期间获得的高分辨率测深和深部多通道地震数据揭示了NLA前臂的构造演化截然不同。
