Abstract: Late Cretaceous to Early Paleogene shallow marine carbonates in the Tethys Himalaya of southern Tibet importantly record the historical evolution of the northern Indian continental margin and the closure of the Neo-Tethys Ocean. In this study, we collected polarized microphotographs of the carbonate and mixed carbonate-siliciclastic rocks from Late Cretaceous Bolinxiala Formation, Jiubao Formation, Zhepure Shanpo Formation and Early Paleogene Zongpu Formation in Tibetan Himalaya by using polarized microscope. The photomicrograph dataset includes 465 carbonate and mixed carbonate-siliciclastic samples from five stratigraphic sections. The dataset not only includes information on sampling location, but also describes the stratigraphic age, lithology and petrology of the samples. It provides basic geological information for reconstruction of the sedimentary environment before and after the initial India-Asia continental collision and the closure of Neo-Tethys Ocean.
