为了探讨普林斯巴晚期碳循环扰动以及相应的气候环境变化对该地区的碳酸盐台地生物演化过程影响，对藏南札达地区普普嘎组出露较好的东秋剖面开展了研究和样品采集。本剖面共测试有机碳同位素40个样品，无机碳氧同位素供测试34个样品；并鉴定54张岩石薄片有孔虫种属，共统计414个有孔虫，涉及35属48种；定量统计每张薄片的颗粒含量。\n数据集存储为.xlsx格式。
", "ds_source": "有孔虫鉴定和点计法定量统计生屑颗粒和相分析，本研究利用PhotoQuad软件将薄片图像圈出一定大小（1.8 cm×2.7 cm）的合适区域并等间距投点，按照excel表对每个点逐一定名。对每张薄片统计375个点，进而确保统计结果的准确性。
