Controls on depositional cyclicity: interplay of global and local processes in the Canterbury Basin, New Zealand

该项目旨在分析位于新西兰南岛东部边缘的Cantebury盆地海上采集的多通道地震数据。对高分辨率多道地震剖面进行解释和制图，并与现有的商业和深穿透学术多道地震剖面相结合，将有助于评估海平面上升、构造、沉积物供应和洋流对地层发育的相对作用。坎特伯雷盆地包括南半球对应的新泽西州边缘：两者都代表硅屑边缘。该分析将定义三维层序几何形状，以揭示层序几何形状的时空变化，并通过使用正演地层模拟来重现观测到的几何形状，评估局部控制与全局控制的相对重要性。

Award is for a project to analyze multichannel seismic data acquired in the offshore Cantebury Basin, on the eastern margin of the South Island of New Zealand. Interpretation and mapping of the high resolution multichannel seismic profiles and integration with existing commercial and deep-penetration academic multichannel seismic profiles will allow evaluation of the relative roles of eustacy, tectonics, sediment supply and currents on stratigraphic development. The Cantebury Basin comprises a southern hemisphere counterpart to the New Jersey margin: both representing siliciclastic margins. The analysis will define the 3-D sequence geometries to reveal spatial and temporal changes in sequence geometry, and evaluate the relative importance of local versus global controls by using forward stratigraphic modeling to reproduce observed geometries.
