Lime mudstone
Five major microfacies types including (lime mudstone, lime wackestone, lime packstone, grainstone, and boundstone) were recognized in the studied formation. • The depositional environment of the formation is shallow marine carbonate environment, with intertidal setting in the lower part and semi-restricted lagoonal environment in the upper part.“Lower part consists of alternating green and maroon lime mudstone, succeeded by yellowish-brown weathering, silty, shaly lime mudstone and wackestone having brachiopods; its upper and greater part consists of light-gray weathering peloid- and ooid-rich lime packstone and grainstone and rare dolomite” (Weber and others, 1992).

Calcareous ooze lithifies as lime mudstone, sometimes re[Lime mudstone samples used in the tests were obtGaotai Formation, as a barrier to water, consisted of mudston Clan designation. As others before him, Folk proposed a classification for sandstones based on the relative abundances of quartz (Q), feldspars (F), and rock fragments (R). These are the main poles of the classification diagram. To define the clan name one must normalize the sum of abundances of quartz, feldspars and rock fragments to 100%.Oct 1, 2021 · Homogeneous lime-mudstone.
