Individual event, seasonal and interannual variations in δ¹⁸O values of drip water in Maomaotou Big Cave, Guilin, South China, and their implications for palaeoclimatic reconstructions

Accurately interpreting the stable oxygen isotopic composition (δ 18 O) of cave drip water is critical to the retrieval of palaeoclimatic information based on the δ 18 O records preserved in speleothem calcite. Substantial cave monitoring data sites of interest can make essential contributions. In this study, six speleothem drip water sites and one pool water site were selected for a five‐year (2013–2017) monitoring of O and H stable isotope...
