The initial solid constituents of a carbonate rock normally determine its initial pore type and geometry and strongly influence diagenesis. Early pore space in carbonate rocks generally has fabric-selective characteristics; creation of late pore space does not.<ref name=ch09r10>Choquette, P. W., Pray, L.

Late-stage shallow diagenesis mainly occurs in nonfabric-selective pore geometries that allow the greatest fluid flow (mostly [[fracture]] related). Deep diagenetic processes can be both fabric selective (fluid flow through interparticle or intercrystalline pores) or nonfabric selective (compaction).
