lODP Exp. 317 Canterbury Basin - environmental magnetism and dating of Miocene through recent sedimentary sequences

lODP Exp. 317将侧重于全球海平面（eustasy）与局部构造和沉积过程在控制大陆边缘沉积旋回中的相对重要性。厄巴特先生被邀请作为船上的古地磁学家出航。主要目标（本提案）包括建立一个可靠的时间框架，用于利用磁地层学钻探沉积物，包括船上和巡航后的改进。进一步的目标，主要是巡航后的研究，包括环境磁方法，以表征（古）环境因素，包括控制坎特伯雷盆地沉积记录的海洋环流。磁性矿物已被证明能灵敏地反映各种海洋沉积物中的微小沉积/地球化学变化。研究结果将主要改善迄今为止地震分解的层序结构和各自的沉积控制。巡航后的环境磁研究将集中在序列边界4 - 5 (12.4 - 11 Ma)，并将与非磁数据（如地球化学、沉积学）相结合，由船上的科学小组和巡航后的合作确定。

lODP Exp. 317 will focus on the relative importance of global sea level (eustasy) versus local tectonic and sedimentary processes in controlling continental margin depositional cyclicity. M. Urbat is invited to sail as a shipboard paleomagnetist. Principal objectives (this proposal) include the establishment of a robust time frame for the sediment drilled using Magnetostratlgraphy, both shipboard and postcruise for refinements. Further objectives, mainly of the post-cruise studies, comprise environmental magnetic methodology as to characterize (paleo-)environmental factors includeing ocean circulation which control the Canterbury Basin sedimentary record. Magnetic minerals have been shown to sensitively reflect minute depositional/geochemical changes in a variety of marine sediments. Results will improve the so far mainly seismically resolved sequence architecture and respective depositional controls. Post-cruise environmental magnetic research will focus on sequence boundaries 4 - 5 (12.4 - 11 Ma) and will be integrated with non-magnetic data (e.g. geochemistry, sedimentology) to be determined on-board by the shipboard scientific party and in post-cruise collaboration.
