1. Limestone Bedrock

   Linked via "calcite crystals"

   The fundamental susceptibility of limestone to acid dissolution makes it an excellent proxy for reconstructing past atmospheric carbon dioxide levels and precipitation acidity. Detailed analysis of isotopic ratios ($\delta^{18}\text{O}$ and $\delta^{13}\text{C}$) preserved within burial cements provides robust paleoclimatic data (Isotopic Signatures in Earth Sciences, 2005).
   However, a significant compl…
