δ18O and δD of gypsum hydration water as measured from Karsandi paleolake (open blue diamonds), and predicted paleo-lake water values for Karsandi (closed blue diamonds) after correction for fractionation factors27. The local meteoric water line (LMWL) is based on GNIP data from Delhi32. The solid blue line represents the evaporative line estimated from the corrected Karsandi data. Surface water samples (red filled circles) from nearby Riwasa village28,29 are plotted for comparison.
