Cenomanian-Turonian Eagle Ford Research: Core dataset

This integrated dataset contains 15 years of data acquisition, analysis, and interpretation of two (Iona-1; Innes-1) Cenomanian-Turonian age shallow research cores (each >100 m long) that penetrated rhythmically interbedded calcareous mudstones, limestones and numerous bentonites that comprise the Eagle Ford Group in West Texas, as well as the underlying Salmon Creek and Buda Limestones and overlying Austin Chalk. These cores and data have been the focus of over twenty-five peer-reviewed papers. A highly resolved astronomical age model was developed constrained with high precision dating of bentonites, biostratigraphy and stable isotope stratigraphy. These data demonstrate the value of integrated, high-resolution mudstone studies (including lithology, mineralogy, inorganic and organic geochemistry, stable and radiogenic isotope, biostratigraphy, astrochronology, core photography, core and well log, and other data) —not only for regional basin analysis, tectonics and stratigraphic studies, but also for advancing our understanding of mudstones, greenhouse climate states, Cretaceous Earth system evolution and carbon cycle dynamics, and pulsing of Large Igneous Provinces. We hope others will use the data in their analyses of global Late Cretaceous.本集成数据集涵盖了针对两根（Iona-1、Innes-1）森诺曼期-土仑期（Cenomanian-Turonian）浅海科研岩心开展的15年数据采集、分析与解译工作，单根岩心长度均超100米，穿透了构成德克萨斯西部鹰福特群（Eagle Ford Group）的韵律互层钙质泥岩、灰岩与多层斑脱岩，同时覆盖其下伏的鲑鱼溪组（Salmon Creek）、巴组灰岩（Buda Limestones）以及上覆奥斯汀白垩（Austin Chalk）。该套岩心与配套数据集已成为25余篇同行评议学术论文的核心研究对象。研究团队基于斑脱岩高精度定年、生物地层学与稳定同位素地层学约束条件，构建了高分辨率天文年代标尺。这些数据证实了集成化高分辨率泥岩研究的重要价值——此类研究涵盖岩性学、矿物学、无机与有机地球化学、稳定同位素与放射成因同位素分析、生物地层学、天文年代学、岩心摄影、岩心与测井数据及其他相关数据维度——不仅可支撑区域盆地分析、构造学与地层学研究，还可推动学界对泥岩、温室气候状态、白垩纪地球系统演化、碳循环动力学以及大火成岩省（Large Igneous Provinces）脉动机制的认知。我们期望全球晚白垩世相关领域研究者能够复用该数据集开展相关分析研究。
