Our compilation of marine magnetics of the Caribbean Plate allows us to identify magnetic anomalies from the Cretaceous Normal Superchron (CNS) in the Colombia and Venezuela basins, from which we propose a model for the age and origin of the Caribbean Plate and its Large Igneous Province (CLIP). The comparison of selected marine magnetic profiles across these basins with high resolution profiles from other areas across the CNS indicates that the Colombia Basin formed 73-92 million years ago (Ma) and the Venezuela Basin 92-108 Ma. The two basins and the older part of the CLIP formed at a ridge axis in the Pacific Ocean, near the Central American Seaway. These results strongly constrain regional plate tectonic models for America and the Pacific Ocean.

我们对加勒比板块海洋磁学的汇编使我们能够从哥伦比亚和委内瑞拉盆地的白垩纪正常超时区（CNS）中识别出磁异常，从中我们提出了加勒比板块及其大型火成岩省的年龄和起源模型（夹子）。将这些盆地的选定海洋磁剖面与 CNS 其他区域的高分辨率剖面进行比较，表明哥伦比亚盆地形成于 73-92 百万年前 (Ma)，委内瑞拉盆地形成于 92-108 Ma。两个盆地和 CLIP 的较旧部分形成于太平洋的脊轴，靠近中美洲海道。这些结果强烈限制了美洲和太平洋的区域板块构造模型。
