Major/trace element and Sr-Nd-Pb isotope geochemistry of New Zealand South Island sediments

Abstract: To facilitate accurate tracing of the extent of aeolian and oceanic transport of NZ dust, this dataset presents major/trace element and Sr-Nd-Pb isotope ratios on 20 sediments from the major present-day dust and sediment producing regions of the South Island. Samples were size-separated using Stokes settling to obtain the <5 µm fraction, then digested using HF-HNO3.

摘要：为精准示踪新西兰（New Zealand，简称NZ）粉尘的风成与海洋搬运范围，本数据集收录了取自南岛当前主要粉尘及沉积物产出区的20份沉积物的常量/微量元素（major/trace element）与锶-钕-铅同位素比值（Sr-Nd-Pb isotope ratios）。样品采用斯托克斯沉降（Stokes settling）法进行粒度分选，获取<5微米（µm）组分，随后通过氢氟酸-硝酸（HF-HNO3）体系进行消解。
