Snack's 1967» But the story doesn’t end at burial. Carbonate sediments are . As soon as they are deposited, they meet corrosive, meteoric (rain) water or subsurface brines. This is diagenesis —the great rewrite.
Carbonate sedimentary rocks, primarily limestones and dolostones , constitute approximately 20–25% of the earth's stratigraphic record. Unlike clastic rocks formed from physical weathering, carbonates are unique "archival" rocks often generated through biological mediation within a depositional system known as the "carbonate factory". 1.

Carbonate sedimentary rocks form the bedrock of critical geological systems. They comprise approximately one-fifth of the global stratigraphic record. These lithologies serve as the primary reservoirs for significant global groundwater resources and major hydrocarbon accumulations. Furthermore, they function as long-term carbon sinks that regulate the global climate across tectonic timescales. But the story doesn’t end at burial
Microbial activity (primarily by cyanobacteria in microbial mats) alters the local microenvironment. Photosynthesis consumes CO2CO sub 2 This is diagenesis —the great rewrite
