Carbonate mudstones are key geochemical archives for past seawater chemistry, yet the origin of carbonate mud remains a subject of continued debate and uncertainty. Prevailing hypotheses have settled on two mechanisms: (1) direct precipitation in the water column and (2) postmortem dispersal of mud‐sized algal skeletal components. However, both mechanisms conflict with geochemical observations in modern systems and are problematic in deep time. We tested the hypothesis that abrasion of… 
Microbially Induced Carbonate Precipitation in a Middle Triassic Microbial Mat Deposit from Southwestern China: New Implications for the Formational Process of Micrite
Lime mud (i.e., micrite) is a major component of carbonate deposits. Various mechanisms (biotic versus abiotic) have been proposed for the formation of lime mud in Earth’s history. However, the
Holocene sediment distribution in the Al Wajh platform lagoon (northern Red Sea, Saudi Arabia), a modern analogue for large rift basin carbonate platforms
Sedimentary patterns and hydrodynamic transport processes on modern carbonate platforms in arid climates are understudied compared to platforms in humid‐tropical climates. The Al Wajh platform –

Geologists have documented at least 14 occurrences of “giant ooids,” a geologically rare type of carbonate allochem, in Neoproterozoic successions at low paleolatitudes. Recent experiments and
An Assessment of Cilacap Coast's Total Carbonate Sediment Content
Sediments are particles derived from the dismantling of rocks from the land and pieces of shell and remains of marine organisms that contain organic matter, included carbonate sediment. The total


Carbonate factories: A conundrum in sedimentary geology
Experimental Deposition of Carbonate Mud From Moving Suspensions: Importance of Flocculation and Implications For Modern and Ancient Carbonate Mud Deposition
Abstract Flume experiments with fine-grained carbonate particles (< 62.5 µm) show that they form floccules that travel in bedload, form current ripples, and deposit laminated sediments. In order to
The origin of carbonate mud in isolated carbonate platforms of Belize, Central America
Abstract.Carbonate mud from three small isolated carbonate platforms of Belize (Central America) is largely a product of the breakdown of skeletal grains. The composition of the 63–20- and 20–4-µm
Controls on platform‐scale patterns of surface sediments, shallow Holocene platforms, Bahamas
Isolated carbonate platforms occur throughout geological history, and commonly exhibit considerable spatial variability. To evaluate the controls on the nature of sediment accumulation across the

Whitings, a sedimentologic dilemma
Whitings, drifting clouds of water, milky because of suspended carbonate, have been claimed to originate from either the action of bottom-feeding fish or direct precipitation of calcium carbonate.
Quantitative bounds on morphodynamics and implications for reading the sedimentary record.
It is shown that the advection length for settling sediment sets bounds on the scales over which internal landscape dynamics operate that provide a universal palaeohydraulic reconstruction tool on planetary surfaces and allow for quantitative identification of depositional systems that may preserve tectonic, climatic and anthropogenic signals.
South Florida Basin--A Prime Example of Carbonate Source Rocks of Petroleum
Stratigraphic, lithologic, and geochemical data provide ample evidence that carbonate rocks and not shales are the source beds of commercial oil in carbonate grainstone reservoirs of the Lower
