Clay mineralogy of sdiment core PS2187-5 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. Smectite, illite, kaolinite and chlorite by area, kaolinite/chlorite by intensity通过假设黏土组分仅由黏土矿物构成，借助比斯开（Biscaye）1965年提出的因子，将代表黏土矿物族的峰面积转化为相对黏土矿物百分含量。其中蒙脱石、伊利石、高岭石与绿泥石的含量基于峰面积计算，高岭石/绿泥石的比值则基于峰强度确定。
