IODP Expedition 390C ICP-AES elemental analysis (solids)

Elemental contents in hard rock and sediment samples was measured by inductively coupled plasma - atomic emission spectrocopy (ICP-AES). Data are presented by element-wavelength pair (e.g., more than one calcium line may be reported). Elemental lines for which data do not exist for a particular expedition will not appear.硬岩与沉积物样品的元素含量采用电感耦合等离子体原子发射光谱法（inductively coupled plasma atomic emission spectroscopy，ICP-AES）进行测定。数据以元素-波长对的形式给出（例如，可同时报告多条钙特征谱线的检测结果）。针对特定考察航次未获取到有效数据的元素谱线，将不会被纳入本数据集。
