9618673 Housen This project will identify the degree of diagenesis of magnetic minerals in sediments from he Barbados, Cascadia and Nankai prisms. Magnetic anisotropy can reveal deformation, but only if diagenesis can be accounted for. The PI will compare magnetic, sedimentologic and chemical properties of samples taken from the prisms with those of equivalent age from cores seaward of the prisms.

9618673 Housen 该项目将确定巴巴多斯、卡斯卡迪亚和南海棱镜沉积物中磁性矿物的成岩作用程度。 磁各向异性可以揭示变形，但前提是可以解释成岩作用。 PI 将从棱镜中采集的样本与从棱镜向海的岩心中采集的同等年龄的样本进行磁性、沉积学和化学性质的比较。
