This is a detailed magnetic study of seafloor spreading in the Cayman Trough, Caribbean Sea using high denisty aeromagnetic data and three dimensional magnetic inversion procedures. The trough offers a look at seafloor spreading and crustal accretion from three unique persepctives; as an indicator of relative motion sand tectonic desplacements within a complex plate boundary zone, as an example of accretion occurring under extreme thermal, tectonic and spreading conditions, and as an example of anisolated spreading cell whose development can be mapped from the time of its formation.

本文利用高密度航磁资料和三维磁反演方法对加勒比海开曼海槽海底扩张进行了详细的磁研究。该海槽从三个独特的角度审视了海底扩张和地壳加积：作为复杂板块边界带内相对运动和构造位移的指示器，作为在极端热、构造和扩张条件下发生加积的例子，作为一个孤立扩张单元的例子，其发展可以从其形成之时开始绘制。
