Journal of Paleontology 72(5) :907-927. Belongs to Georgiacetus according to M. D. Uhen 2014. Sister taxa: none. Type specimen: GSM 350, a partial skeleton. Its type locality is Vogtle Electric Generating Plant, which is in a Lutetian deep subtidal shelf lime mudstone in the Blue Bluff Formation of Georgia. Ecology: scansorial insectivore.Jan 15, 2002 · The pebble-grade lime–mudstone and dolo–mudstone clasts between stromatolites most likely formed in an intertidal to supratidal zone during flooding by erosional rip-up of mudcracked polygons produced by subaerial exposure, similar to the interpretation of Young et al. (1972). For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains in a mud-supported sediment); lime packstone (grain-supported limestone with mud matrix between the grains); lime grains...The 12 lithologies recognized within the stratigraphic sections reflect the interaction between contemporaneous shallow-water carbonate ramp environments and a siliciclastic-dominated intrashelf basin. Deposition on the carbonate ramp was in the form of lime mudstone and wackestone and oolitic and oncolitic packstone and grainstone.

In order to investigate the mechanical properties of lime mudstone, conventional triaxial compression tests under different confining pressures (0, 5, 15 and 20 MPa) are performed on lime mudstone samples. The test results show that, from the overall perspective of variation law, the axial peak stress, axial peak strain and elastic modulus of lime mudstone tend to gradually increase with ...For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains in a mud-supported sediment); lime packstone (grain-supported limestone with mud matrix between the grains); lime grains...The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental. …About Lime-mudstone Hide. A limestone with at least 75% mud grade (< 32μm) calcium carbonate. Compare with mud-grade limestone.

Feb 1, 2022 · TST1: This system tract comprises phosphorite at the base and is overlain by shale, marl, lime mudstone, and porcellanite-rich planktic and organic matter, dominated by FA1 and smectite–calcite assemblage in most of the studied sections (Figs. 1, 4, 5 and 71-12). The MFS content reaches a maximal percentage of planktic foraminifera and ... Siltstone forms in low-energy marine environments, and is an intermediate rock type between mudstone and sandstone. While siltstone is a clearly defined rock type, it can still be difficult to know whether a rock you’ve found is a siltstone. It can easily be confused for similar, closely related rocks.Mar 17, 2013 · Red, nodular, burrowed, bioclastic lime mudstone and wackestone (with echinoderm remains, foraminifera, ostracods, radiolaria, bivalves, gastropods, ammonoids; Fig. 6a, b). The characteristic feature of this microfacies type is the occurrence of partly rounded limestone nodules embedded in a muddy, fine-bioclastic, marly matrix (Fig. 7g). The ... …
