==Early diagenesis and pore-system quality==

[[:file:predicting-reservoir-system-quality-and-performance_fig9-75.png|Figure 2]] shows the general pathways that different carbonate rock types might take during early diagenesis as their pore systems evolve. The parallel lines are contours of equal pore throat size. In terms of quality, points plotting along the contours represent rocks with equal flow characteristics (''see'' [[Characterizing rock quality]] earlier in this chapter). With the exception of the creation of connected vugs and dolomitized mudstone, carbonate rocks generally lose porosity and permeability as a result of diagenesis.
