Short summary

In this study, we conclude that surface weathering is a primary control on rock characteristics and also guides fluids through the system during deep burial process. We also find that the formation of the rock decomposition zone depends on rock composition, climatic conditions and the duration of the process. Finally and most importantly, we provide a workflow for data reliability analysis for paleoclimate research.
