The position of several blocks of continental crust during the Permian-Triassic closure of the Gulf of Mexico- Caribbean region are presently unconstrained, yet must be accommodated in any model. This project will obtain paleomagnetic data from one of the larger of these enigmatic central American Blocks- the Yucatan block presently exposed in Belize and Guatemala. Paleopoles of late Paleozoic and Mesozoic strata may constrain the paleolatitude and relative position of Yucatan during the existence of Pangea and the incipient break up to form the Gulf/Caribbean region.

在墨西哥湾-加勒比地区二叠纪-三叠纪闭合期间，几个陆壳区块的位置目前不受限制，但必须以任何模式容纳。该项目将从这些神秘的中美洲地块中较大的一个--目前暴露在伯利兹和危地马拉的尤卡坦地块--获得古地磁数据。晚古生代和中生代地层的古极可能制约着盘古时期尤卡坦半岛的古纬度和相对位置，以及形成海湾/加勒比海地区的早期解体。
