西藏阿里地区双点达坂剖面海相碳酸盐岩无机碳同位素地化数据（359-340 Ma）

华南地区石炭纪海相碳酸盐的δ13C值标准曲线已建立, 但是国内不同地区和不同剖面之间的δ13C值变化趋势却存在一定差异。在应用碳同位素记录重建海洋碳循环之前, 尚需要开展沉积环境和成岩作用分析，并将碳同位素记录的变化趋势进行跨相、跨盆地和跨板块对比，以确定其是否记录了区域或全球海洋的碳同位素组成变化。本次研究在阿里地区双点达坂剖面月牙湖组共采集201块样品开展碳氧同位素分析测试，试图揭示北羌塘/松潘甘孜地块石炭纪早期的碳循环过程（TICE 事件）和碳同位素记录的成岩改造作用。本数据集包括201个样品的碳氧同位素数据。

A standard δ¹³C curve of Carboniferous marine carbonates has been established in South China, but there are certain differences in the δ¹³C variation trends between different regions and sections within China. Prior to reconstructing the marine carbon cycle using carbon isotope records, it is necessary to conduct analyses of sedimentary environments and diagenesis, and perform cross-facies, cross-basin, and cross-plate comparisons of the variation trends of carbon isotope records to determine whether they record the carbon isotope composition changes of regional or global oceans. In this study, a total of 201 samples were collected from the Yueyahu Formation at the Shuangdian Daban Section in the Ngari Area for carbon and oxygen isotope analysis and testing, aiming to reveal the Early Carboniferous carbon cycle processes (TICE event) and the diagenetic alteration of carbon isotope records in the North Qiangtang/Songpan-Garzê Block. This dataset contains carbon and oxygen isotope data from 201 samples.
