Together with a PhD student, the applicant plans to study Late Pleistocene volcaniclastic turbidites and debrites, which have been drilled and recovered west of Dominica and Martinique (Lesser Antilles) in March-April 2012 during IODP Cruise 340 (the applicant was ship party member of this cruise). The project comprises detailed analysis of the depositional facies, grain shape, composition of 221 samples that have been taken in August 2012 from cores of Sites U 1397 and 1398. The results will be supported by biostratigraphic and paleobathymetric investigation of the biogenic component in each sample, carried out by the Freiberg research group. Further confirmation of our models is expected from integration of ship board data (petrophysics, drill hole logging etc.) and findings of other IODP 340 research groups (e.g. chronostratigraphy). Focus of the proposed project is a quantitative 3D analysis of the shape and internal texture of volcanigenic grains. Apart from completion of knowledge on the volcanic evolution of the Lesser Antilles arc, we want to test to what extent textural/compositional analysis of turbidites allows for confident assumption on their origin and triggering mechanism.

申请人与一名博士生一起，计划在2012年3月至4月在IODP Cruise 340期间，在2012年3月至4月在2012年3月至4月在Dominica和Martinique（Liseer Antilles）进行钻探和回收的更新世火山碎屑和碎屑（申请人是该巡航的船舶党员）。该项目包括对沉积相，晶粒形状，221个样品组成的详细分析，这些样品已于2012年8月从u1397和1398的地点核心进行。结果将由Freiberg Research Group携带的每个样品中的生物地层学和生物学分量研究支持。通过整合船舶板数据（岩石物理学，钻孔记录等）以及其他IODP 340个研究小组（例如年级地层学）的发现，可以进一步确认我们的模型。拟议项目的重点是对火山晶晶粒的形状和内部质地进行定量的3D分析。除了完成有关小安特列斯（Antilles）弧的火山演化的知识之外，我们还希望测试浊度的纹理/组成分析在多大程度上可以自信地假设其起源和触发机制。
