Collaborative Research: An Integrated Seismic Experiment Across A Continental Rift: The Newark Basin

该项目包括获取垂直地震剖面，并结合高分辨率反射测量，从新泽西州纽瓦克裂谷盆地三叠纪沉积物中记录的气候旋回地层学中提供广角和窄角反射。纽瓦克盆地科学钻探项目的岩心孔之间的少量地层重叠进一步证明了使用高分辨率地震剖面来有效地将单个地层从一个孔连接到另一个孔的合理性。旋回地层学的最佳表现是在洛通组和下巴塞组。每个岩心只取样于一个岩心洞，即新泽西州默瑟县拉蒙特南部样带的泰特斯维尔和彭宁顿附近的岩心洞。为了追踪岩心孔间反射率和层间速度的变化，需要详细的速度信息和高分辨率地下图像，而VSP和高分辨率地面地震调查可以提供这些信息。这些测量记录的速度和反射率应与湖深指数相关，利用高分辨率地面地震测量可以追踪岩心孔之间的变化，以评价岩心孔之间序列的连续性以及复合Van Houten旋回间距和湖深指数随盆地东岸的变化。这种控制将为解释有关全盆地旋回的岩心数据提供额外的限制。

This project involves the acquisition of a vertical seismic profile integrated with a high-resolution reflection survey which will provide both wide- and narrow-angle reflections from the climatic cyclostratigraphy recorded in the Triassic sediments of the Newark Rift Basin, New Jersey. The small amount of stratigraphic overlap between the core holes of the Newark Basin Scientific Drilling Project further justifies the use of high resolution seismic profiling to effectively tie single formations from one hole to another. The best manifestation of the cyclostratigraphy occurs within the Lockatong and lower Passaic formations. Each will be sampled by only a single core hole, the holes near Titusville and Pennington of Lamont's southern transect in Mercer County, New Jersey. To trace facies variations amounting to changes in reflectivity and interval velocity between core holes requires the detailed velocity information and high resolution subsurface images that can be provided by VSP and high resolution surface seismic surveys. The velocities and reflectivities recorded by these surveys should correlate with lake depth index variations can be traced between core holes using the high resolution surface seismic surveys to evaluate the continuity of sequences between the core holes as well as changes in composite Van Houten cycle spacing and lake depth index with proximity to the eastern shore of the basin. Such controls will provide additional constraints for interpretation of the core data with respect to basin wide cyclicity.
