δ¹³C and δ¹⁸O limestone records as proxies for Mid-Carboniferous climate in Northwestern Mexico

δ¹³Ccarb and δ18Ocarb values in 38 limestone samples from the Mississippian-Pennsylvanian Boundary (MPB) cropping out in the Sierra Agua Verde, and 16 samples from the southwestern sector of Cerro Las Rastras, both located in Sonora, NW Mexico.

本数据集涵盖采自墨西哥西北部索诺拉州的两组石灰岩样品的碳酸盐碳同位素（δ¹³Ccarb）与氧同位素（δ¹⁸Ocarb）值：一组为塞拉阿瓜韦尔德山脉出露的密西西比纪-宾夕法尼亚纪界线（MPB）的38件样品；另一组为拉斯拉斯特拉山西南部区域的16件样品，两处采样点均位于墨西哥西北部索诺拉州。
