An online automated carbonate preparation system linked to a VG Prism II isotope ratio mass spectrometer at the University of Southern California

equilibrium is evidenced by the lack of correlation among d18O and d13C, several Hendy test in laminations and calculations of explected d18O in modern calcite knowing cave temperatue and d18O from dripwaters (in a previous paper, Sinha et al. GRL (2007)

No chron data in current LiPD file, needs updating, updated fiel sent to Nick 31/12/19 (MJ)

more positive values of d18O are interpreted to reflect less rainfall throughout the "amount effect"

more negative values of d18O are interpreted as indicative of increased summer monsoon precipitation

Finnigan MAT-252 mass spectrometer equipped with Kiel Carbonate Device III in the Institute of Earth Environment, Chinese Academy of Sciences

NBS 19 and TTB1 (interlaboratory comparison)

duplicates were run every 10 to 20 samples

equilibrium is evidenced by the Hendy test in several laminae and the lack of correlation among d18O and d13C

LCB (28/03/2019): one of the SP10CACN stals is at higher resolution but I cannot distinguish which is which in lipdverse to pick it as the primary one

4 to 77 in one stalagmite and 36 to 112 in the other
