Mineral composition of Heinrich events 8, 9, and 10 samples@en

Nine samples from Heinrich events 8, 9, and 10 were obtained from cores HU91020-074 and HU204024-042 which are located some 1900 km south of Hudson Strait in the area of the Flemish Cap and Orphan Knoll. Samples were also processed on the < 45 µm fraction in order the assess the impact of foraminifera on the wt% of calcite. Mineral wt%s and source fractions from SedUnMix with and without calcite wt%.本研究从采自哈德逊海峡以南约1900公里处弗莱明海台（Flemish Cap）与孤儿海丘（Orphan Knoll）区域的两个沉积物岩芯HU91020-074和HU204024-042中，获取了海因里希事件8、9、10的9份样品。为评估有孔虫对方解石重量百分比的影响，研究人员对样品的<45微米粒级组分开展了前处理。本数据集同时包含采用沉积物端元混合模型（SedUnMix），分别在纳入与未纳入方解石重量百分比约束条件下计算得到的矿物重量百分比及端元源组分。
