Clay mineralogy of sdiment core PS2175-4 in the Arctic Ocean

Peak areas representing the clay mineral groups are transformed into relative clay mineral percentages by means of Biscaye's factors (1965) using the assumption that the clay fraction consists only of clay minerals将表征各黏土矿物组的峰面积，借助Biscaye于1965年提出的因子系数转换为黏土矿物相对百分含量，该转换基于“黏土级分仅由黏土矿物组成”的假设前提。
