This dataset includes contents, stable carbon and oxygen isotopes of carbonates in the Qom section, Central Iran. Stable carbon and oxygen isotopes from carbonates are important climatic proxies in paleoenvironmental reconstruction. The sediment samples were grounded and sieved through a 100 mesh screen, and then directly analyzed using an isotope ratio mass spectrometer (MAT-252) with an automated carbonate preparation device (Kiel Ⅱ). C, O isotope ratios are converted to Vienna Pee Dee Belemnite (V-PDB) standards. Typical analytical errors for C, O isotope are within ±0.1‰ (±0.06‰ and ±0.08‰ for carbon isotope and oxygen isotope, respectively). The carbonate content was measured by neutralization titration with an accuracy of 0.5%. The ages of the data were obtained by linear interpolation based on magnetostratigraphy. Based on the carbonate concentrations and the stable carbon and oxygen isotopes of the Qom Basin the Miocene paleoenvironmental evolution history can be well reconstructed, being useful for discussing the environmental effects of the uplift of the Arabia-Eurasia collision and the global climatic changes. This study aims to analyze the history of climate change in central Iran since the mid-late Miocene, and finally reveals the intensification of aridity in central Iran since 13 Ma.
