Lime mudstone.
Mudstone–wackestone. 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.

Calcirudite consisting of grains > 2 mm (lime-rubble) and representing the carbonate parallel of a conglomerate. Several authors use calcirudite irrespective of the rounding of grains, but some authors use lime-breccia for limestones with angular clasts. Calcarenite is a limestone with sand-sized (0.0625 – 2 mm) carbonate grains (lime-sand). Calcareous ooze lithifies as lime mudstone, sometimes referred to as pelagic limestone. Below the CCD, only dust and silica can deposit, as the calcareous organisms dissolve before reaching the sea floor, and siliceous ooze accumulates more quickly than red clays.

Uses of Limestone.Grains are crinoid fragments. Under the Dunham classification (Dunham, 1962) [1] system of limestones, a grainstone is defined as a grain-supported carbonate rock that contains less than 1% mud-grade material.

Smackover: 1) transgressive lime mudstone and dolomudstone, 2) microbial (thrombolite) boundstone), 3) microbially-influenced packstone to mudstone, 4) subtidal wackestone and lime mudstone, 5) peloid-ooid nearshore/shoal grainstone, 6) tidal channel rudstone and floatstone, and 7) peritidal wackestone and lime mudstone.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.Its type locality is Solnhofen (BSPGM Munich coll), which is in a Tithonian lagoonal/restricted shallow subtidal lime mudstone in the Solnhofen Formation of Germany.
