Bulk geochemistry of San Francisco and Marin county beach and offshore sediment

Elemental contents are given for bulk (non size-fractionated) beach and offshore sediment. Sediment chemical compositions were determined by ICP-MS following a four-acid sediment-decomposition step. \"<\" indicates values below the analytical detection limit.

本数据集收录了未按粒径分馏的块状海滩与近海沉积物的元素含量数据。沉积物的化学成分经四酸消解前处理后，通过电感耦合等离子体质谱法（ICP-MS）完成测定。符号“<”表示对应数值低于分析检测限。
