As proposed, this term avoids any reference to either a specific origin or depositional environment.

These fossils help scientists to date the core and to understand the depositional environment in which the rock units formed.

Ichnofacies are groups of trace fossils that together help give information on the depositional environment.

The ancient depositional environment of the region around what is now the park varied.

Their depositional environment was a shallow marginal sea with rather high accumulation rates of 30 meters/million years.

The characteristics of the rock unit come from the depositional environment and original composition.

It commonly takes place in marine depositional environments where there is organic material.

The algae slows down the flow of water enough to set up a depositional environment.

Phosphates are known to be deposited in a wide range of depositional environments.

The depositional environment in the lower beds was low energy and slightly anoxic.
