Abstract Since plate tectonics has been linked to material flow in the Earth's mantle, it is commonly accepted that convective motion in the sublithospheric mantle results in vertical deflections and horizontal plate motion on the Earths surface. Those mantle flow-driven vertical deflections are recognized through significant signals and traces in the sedimentary records (unconformities and missing sections). Recently, Friedrich et al. (2018) introduced an event-based plume stratigraphic framework that uses such signals in the stratigraphic record to detect the geological evolution near, and on the Earth's surface in areas of interregional scale caused by mantle plume movement. Information about these dynamic processes is stored in geological archives, such as (1) stratigraphic records of sedimentary basins and (2) thermochronological data sets of igneous, metamorphic, and sedimentary rocks. For the first time, this research combines these two geological archives and applies them to the Mesozoic SW Gondwana intraplate environment to retrieve the Parana-Etendeka plume movement prior to the Parana-Etendeka LIP. We compiled 18 stratigraphic records of the major continental and marine sedimentary basins and over 35 thermochronological data sets including >1300 apatite fission-track ages surrounding the Parana-Etendeka Large Igneous Province to test the event-based plume stratigraphic framework and its plume stratigraphic mapping to retrieve the timing and spatial distribution of the Parana-Etendeka plume. The plume stratigraphic mapping, using the stratigraphic records is suitable to demark a possible plume center, plume margins and distal regions ( Friedrich et al., 2018 ). Thermochronological data reveal centers of a significant thermal Parana-Etendeka plume influence. Both archives show significant signals and traces of mantle plume movement well in advance of the flood basalt eruptions. Our LTT data combined with stratigraphic records are modeled successfully with respect to a viable mantle plume driven thermal evolution and therefore, we suggest that thermochronological data, in combination with stratigraphy records have the potential to retrieve the Parana-Etendeka plume movement.

应用地层框架和热年代学数据在中生代西南冈瓦纳板内环境中检索巴拉那-埃滕德卡羽流运动

摘要 由于板块构造与地幔中的物质流动有关，人们普遍认为亚岩石圈地幔中的对流运动会导致地球表面的垂直偏转和水平板块运动。这些地幔流驱动的垂直偏转是通过沉积记录（不整合面和缺失部分）中的重要信号和痕迹来识别的。最近，弗里德里希等人。(2018) 介绍了一种基于事件的羽流地层框架，该框架使用地层记录中的此类信号来检测地幔柱运动引起的区域间尺度区域附近和地球表面的地质演化。这些动态过程的信息存储在地质档案中，例如 (1) 沉积盆地的地层记录和 (2) 火成岩、变质岩和沉积岩的热年代学数据集。本研究首次将这两个地质档案结合起来，并将它们应用于中生代西南冈瓦纳板内环境，以检索巴拉那-埃滕德卡 LIP 之前的巴拉那-埃滕德卡羽流运动。我们汇编了主要大陆和海洋沉积盆地的 18 个地层记录和超过 35 个热年代学数据集，包括超过 1300 个围绕巴拉那-埃滕德卡大型火成岩省的磷灰石裂变径迹年龄，以测试基于事件的羽状地层框架及其羽状地层图检索巴拉那-埃滕德卡羽流的时间和空间分布。羽状地层图，使用地层记录适合划分可能的羽流中心、羽流边缘和远端区域（Friedrich et al., 2018）。热年代学数据揭示了重要的巴拉那-埃滕德卡热羽流影响中心。两个档案都显示了在洪水玄武岩喷发之前很久的地幔柱运动的重要信号和痕迹。我们的 LTT 数据结合地层记录成功地模拟了可行的地幔柱驱动的热演化，因此，我们建议热年代学数据与地层记录相结合有可能恢复巴拉那-埃滕德卡柱流运动。两个档案都显示了在洪水玄武岩喷发之前很久的地幔柱运动的重要信号和痕迹。我们的 LTT 数据结合地层记录成功地模拟了可行的地幔柱驱动的热演化，因此，我们建议热年代学数据与地层记录相结合有可能恢复巴拉那-埃滕德卡柱流运动。两个档案都显示了在洪水玄武岩喷发之前很久的地幔柱运动的重要信号和痕迹。我们的 LTT 数据结合地层记录成功地模拟了可行的地幔柱驱动的热演化，因此，我们建议热年代学数据与地层记录相结合有可能恢复巴拉那-埃滕德卡柱流运动。
