(a) Blocky calcite cement fills a pore-space formed by dissolution of matrix. (b) Thin-section photomicrograph displays granular calcite fills a microfracture. (c) and (d) Thin-section photomicrographs show the fine-crystalline, replacive dolomites. (e) and (f) Thin-section photomicrographs display the occlusion of open void by medium-grained, zoned, euhedral dolomite cement. (g) Aggrading neomorphism of the micitic matrix into neomorphic spar. (h) Thin-section photomicrograph shows the neomorphic calcitization of gastropod shell into inclusion-rich, granular neomorphic spar. (i) The partial infilling of a void space by quartz cement.
