Photomicrographs (optical microscope and cathodoluminescence) of the Calcaires de Tabalcon unit. a, b Dolomitized and dedolomitized mudstone and late stylolithization in natural light and cathodoluminescence. Blocky calcite (BC) exhibits dull luminescence under CL (sample YM32). c Bioclast affected by compaction exhibiting two stages of blocky calcite cementation (BC1 and BC2, sample YM34). d SEM photograph of dedolomite composed of remaining dolomite and microvugs filling calcite (sample YM77). e, f Planar euhedral dolomite overprinting blocky calcite cementation (BC), in natural light and cathodoluminescence (sample YM40). g, f Sucrosic dolomite with cloudy cores and limpid rims, natural light and cathodoluminescence (sample YM61)
