Of the many ways used to understand seasonal variability I am taking recourse to use of micromilling at ~200 micron resolution and analysing stable isotopes. I need more research material in this regards.
Dear Shaddha
I appreciate that you are retrieving samples at one of the highest possible sampling resolutions. However, It will depend on speleothem growth rate and chronological control. I have seen many related papers on sciencedirect. Few links below may be helpful:

Hey! Thanks a lot. I have gone through the Nature paper. our sample has annual layers but there were some issues with U-Th ages. Hopefully we'll be able to retrieve most information from it.
These articles may be of interest to you, even though they deal with modern systems vs. ancient stalagmite results:

Thanks a lot Prof. Jay! I was going through your chemical geology paper, and I understand the analysis was done on drip water. In our case, sampling of drip water and stalagmite was done few years back. Stable isotope analysis of drip water was carried out after returning from field trip but trace element ratios were not measured. Do you think there will be alteration in the trace element ratios if I measure them now?
Merry Christmas!!
