Paleoproterozoic McArthur Basin, SEDEX deposit, stable carbon and nitrogen isotopes (NERC Grant NE/V010824/1)

Organic carbon and bulk nitrogen isotope data for black shale samples from six different drill cores with varying distance from the major Zn ore body (HYC) in the McArthur basin. Data show trends with distance in d15N and C/N ratios. A more detailed interpretation is provided in Stüeken, E.E., Gregory, D.D., Mukherjee, I. and McGoldrick, P., 2021. Sedimentary exhalative venting of bioavailable nitrogen into the early ocean. Earth and Planetary Science Letters, 565, p.116963.

本数据集涵盖采自6个不同钻探岩芯的黑色页岩样品的有机碳与全氮同位素（bulk nitrogen isotope）数据，各岩芯与麦克阿瑟盆地（McArthur basin）内的主要锌矿体（HYC）间距各不相同。数据表明，δ¹⁵N与碳氮比（C/N ratios）随采样间距的变化呈现出显著趋势。相关更详细的解读可参见下述文献：Stüeken, E.E.、Gregory, D.D.、Mukherjee, I. 与 McGoldrick, P., 2021. 《生物可利用氮经沉积喷流作用释放进入早期海洋（Sedimentary exhalative venting of bioavailable nitrogen into the early ocean）》，刊载于《地球与行星科学通讯（Earth and Planetary Science Letters）》第565卷，第116963页。
