Figure 9. Main types of pores identified in the studied rocks. (A) Interaggregate (yellow arrow) and vugular porosity with remnants of peloidal matrix (red arrow) in shrubstone (uncrossed polarizers, //P). (B) Pores from shrinkage of the laminated clay matrix, partially replaced by blocky dolomite (//P). (C) Vugular porosity, partially reduced by dolomite cementation (//P). (D) Interparticle, intraparticle (red arrow), and vugular porosity (yellow arrow) in intraclastic rock (//P). (E) Detail of intraparticle porosity due to intraclast dissolution in intraclastic calcarenite cemented by silica (//P). (F) Detail of intercrystalline (red arrow) and intracrystalline (yellow arrow) porosity in dolomite (//P).
