Sentence examples for depositional layer from inspiring English sources

Nevertheless, according to Schumacher and Schmincke (1991), such a distinction is difficult to make for PDC deposits produced by hydromagmatic activity (i.e., base surges), because "mixed populations" of aggregates occur in the same depositional layer.

Those depositional layers have been washing into the Gulf of Mexico for eons, trapping life that eventually was transformed into hydrocarbons far below the surface.

The presence of sandy and muddy soft depositional layers indicates that material transfer and mixing took place during mass transport.

At a metric scale, massive and unsorted stoss-depositional layers lying against the upstream face of buried buildings (Gurioli et al. 2002, 2007), or steep-sided truncations of pre-existing deposits (Schmincke et al. 1973; Freundt and Schmincke 1985; Giannetti and Luongo 1994) were interpreted as resulting from internal "pneumatic jumps" in density-stratified dilute PDCs.

Because it is difficult to figure out the depositional interval of the event deposits using too many (amalgamated) or too small number of event deposit layers in the core.

Layering can derive from original sedimentary layering; depositional upbuilding; episodic surface erosion, deposition, and stability; soil production by weathering; vertical or lateral translocation; bioturbation; and various combinations of these.

While macroscopic growth stages indicate episodic times of constant depositional conditions, microscopic layering actually indicates an intermittent deposition with short time changes or alternating conditions.

Depositional terrace deposits have a larger standard deviation in sandstone layer thicknesses than external levees because they are topographically lower, and experience a wider range of turbidity current sizes overspilling from different parts of the channel-belt.

We evaluated buried SOM located below the existing cultivated layer in depositional areas and SOM in the soil profile of eroded landscape areas.

We used radiocarbon dating to correlate event deposits among cores and to estimate the depositional ages of event layers.

The potential to map the structural and depositional inventory (faults, folds, layering along with thicknesses), as well as the potential to easily differentiate between consolidated and unconsolidated material in the near (sub-) surface, remains identical (Fig. 5).
