TL;DR: In this paper, the authors report high resolution carbon isotope (δ 13C) stratigraphy, nannofossil and Sr isotope ratio of marine fossil carbonate from the Cambay Shale Formation of Western India.
Oxygen isotope analysis of bone and tooth enamel phosphate from paleogene sediments: Experimental techniques and initial results
TL;DR: In this article, the chemical procedure for extraction of very small amount (<1000 µg) PO4−3 from bioapatite and on-line mass spectrometric measurement of its δ18O composition by high temperature (∼1450°C) pyrolysis.

Does burial diagenesis reset pristine isotopic compositions in paleosol carbonates
TL;DR: In this paper, the early Oligocene continental carbonates from the fluvial Dagshai Formation of the Himalayan foreland basin, India were used for the recognition of four different types of carbonates: soil, palustrine, pedogenically modified carbonustrine and groundwater carbonates.
