(Figure 4) Sulfur and oxygen isotopic composition of carbonate fluorapatite-bound sulfate (SO4-CFA) and sulfur isotopic composition of pyrite within the laminite (Spyrite)

bulk laminite-sep. = two separate samples were used for extraction of carbonate fluorapatite-bound sulfate and pyrite, bulk laminite- com. = the combined (three-step) method was used on one sample for extraction of carbonate fluorapatite-bound sulfate and pyrite, ees = easy […]bulk laminite-sep.：采用两份独立样本，用于提取碳酸盐氟磷灰石（carbonate fluorapatite）结合态硫酸盐与黄铁矿；bulk laminite-com.：对单一样本采用三步联合提取法，完成碳酸盐氟磷灰石结合态硫酸盐与黄铁矿的提取；ees = 简易法（easy）[...]
