格林纳达盆地将活跃的小安的列斯岛弧与被称为“加勒比大岛弧”的白垩纪-古新世遗迹的阿夫斯山脊分开。尽管人们提出了格林纳达盆地打开的各种构造模型，但它们所依赖的数据不足以得出明确的结论。本研究介绍了2017年GARANTI巡航期间获得的大量深穿透多通道地震反射数据和疏浚样本。结合已有的地震反射资料、广角地震资料、钻井资料和疏浚资料，我们对格林纳达盆地及其边缘的基底构造、沉积史、构造变形和垂直运动的认识如下：(1)古新世晚期—始新世早期发生了NW—SE方向的裂陷，并在始新世中期导致海底扩张；(2)这个新形成的海洋地壳现在横跨格林纳达盆地东部，位于格林纳达和马提尼克岛的纬度之间；(3)不对称的前中新世沉积支持格林纳达盆地南部最初延伸至现今小安的列斯岛弧南部的假说，并可能在晚渐新世—中新世小安的列斯岛弧上升之前部分延伸至现今的前弧；(4)至少从始新世中期开始，阿夫斯海脊就随格林纳达盆地一起沉降，晚渐新世期间整体沉降减缓甚至隆起，晚中新世期间其东南侧急剧加速。在这种加速下沉之前，几个水深高点仍然很浅，足以形成碳酸盐台地。
The Grenada Basin separates the active Lesser Antilles Arc from the Aves Ridge, described as a Cretaceous‐Paleocene remnant of the “Great Arc of the Caribbean.” Although various tectonic models have been proposed for the opening of the Grenada Basin, the data on which they rely are insufficient to reach definitive conclusions. This study presents, a large set of deep‐penetrating multichannel seismic reflection data and dredge samples acquired during the GARANTI cruise in 2017. By combining them with published data including seismic reflection data, wide‐angle seismic data, well data and dredges, we refine the understanding of the basement structure, depositional history, tectonic deformation and vertical motions of the Grenada Basin and its margins as follows: (1) rifting occurred during the late Paleocene‐early Eocene in a NW‐SE direction and led to seafloor spreading during the middle Eocene; (2) this newly formed oceanic crust now extends across the eastern Grenada Basin between the latitude of Grenada and Martinique; (3) asymmetrical pre‐Miocene depocenters support the hypothesis that the southern Grenada Basin originally extended beneath the present‐day southern Lesser Antilles Arc and probably partly into the present‐day forearc before the late Oligocene‐Miocene rise of the Lesser Antilles Arc; and (4) the Aves Ridge has subsided along with the Grenada Basin since at least the middle Eocene, with a general subsidence slowdown or even an uplift during the late Oligocene, and a sharp acceleration on its southeastern flank during the late Miocene. Until this acceleration of subsidence, several bathymetric highs remained shallow enough to develop carbonate platforms.
