Jan 1, 2013 · Instead, the fine- size carbonate rock is called mudstone (better, lime mudstone) . The rationale of this classification is that it allows one to map gradients in rate of production of sand-size particles relative to rate of accumulation of lime mud. In calm waters, lime mud, if present, settles on the bottom and remains there. 2.4 Definition of shale/mudstone/mudrock. Shale (or mudstone, mudrock) is the most widely used class name for all fine-grained sedimentary rocks that consist more than 50vol.% of silt- and clay-sized particles (<62.5 and <4 μm in diameter) ( Folk, 1980 ).

This rock type is widely distributed and has a lime mudstone or wackestone texture that may be dolomitized at parts with a considerable amount of argillaceous materials (Fig. 6A). It contains a fair quantity of microbial threads, bioturbation, and dwarfed echinoderms.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%.
