Martin Lake isotope geochemistry and sedimentology

This dataset contains oxygen and carbon isotope ratios preserved in sediment cores recovered from Martin Lake, Indiana, USA. Also included is a record of variability in the clastic/lithic fraction of the same sediments. These data span approximately the past 7,000 years.本数据集包含采自美国印第安纳州马丁湖的沉积物岩芯中保存的氧同位素与碳同位素比值数据，同时收录了同一沉积物的碎屑/岩屑组分变化记录。该数据集的时间跨度约为过去7000年。
