Biomarker thermal maturity measurements from IODP sites U1518 and U1520 along the Hikurangi Margin, New Zealand

This dataset includes Carbon Preference Index (CPI), Uk'37, and alkenone concentrations for samples in cores collected between 50 - 500 m depth in site U1518 and between 5 - 500 m in the site U1520. These were collected to examine thermal maturity across the Papaku fault (U1518) and compare fault samples to input sediments to the Hikurangi Subduction Zone to explore evidence of coseismic slip.

本数据集涵盖U1518站位50至500米水深区间、U1520站位5至500米水深区间采集的岩芯样品的碳偏好指数（Carbon Preference Index, CPI）、Uk'37以及烯酮浓度数据。这些样品的采集旨在探究帕帕库断裂带（U1518）沿线的热成熟度，并将断裂带样品与输入希库兰吉俯冲带的沉积物进行对比，以探索同震滑动的相关证据。
