The Wackestone microfacies characterizes inner shelf environment below fair-weather wave base
. The high bioclasts fragments of Grainstone and Wackestone microfacies signify stormy influence in the environment of deposition.
The dominant discontinuous nature of oncoid laminae, which were transported episodically by storm currents, and the lack of tractive structures in the peloidal facies (F2A) suggest that the facies subassociation A1 was deposited in the mid-carbonate platform below the fair-weather wave base
and above the storm wave base
Estimates of absolute depth can be made based upon integrated analysis of a variety of distinctive sedimentary structures related to exposure, indicators of position with respect to shoreline, normal wave base
and storm wave base
, and evidence of light-related zones (Brett et al.
The feature of benthic fauna and stratigraphic relationships with the other microfacies suggest that marl facies were deposited in an open lagoon, calm, deep and normal-salinity water but the co-occurrence of planktonic and some benthic (Nummulitidae) foraminifera in the base of the Asmari marl and marly limestone, suggest that this facies was deposited in calm, low energy hydrodynamic and deep normal salinity water which indicates deposition below the storm wave base
The other is to have more bus stops and or other WAVE base
This suggests the megaripple sandstone/fine grained sandstone/siltstone interbed sequence formed in a fluctuating shallow-marine environment characterized by fluctuating energy conditions in which deposition alternated between just below and within wave base
(Scientists call this depth the wave base
, below which water movement is negligible and the ocean is indeed calm.) Tsunamis often originate when a large earthquake disrupts the ocean floor, displaces and creates waves through the overlying water column.
The discussion of complexities of sea level rise has some convoluted reasoning, including the statement that '[O]ne main effect of sea level rise is an increase in wave base
and a corresponding increase in storm frequency and intensity'.
The presence of diverse fauna and micrite matrix indicates subtidal marine conditions suggesting that AMB 1 facies was deposited below fair weather wave base
under distal middle shelf settings.
The condition of this environment is shallow, with medium to low energy and presence in the photic zone below the fair-weather wave base
. The lagoon is well connected to open marine environments and is temperature and salinity of this environment is close to the open marine.
corals, gastropods, Between wave base
and trilobites, ostracods storm base.
The carbonate deposition generally occurs below wave base
