Depositional Environment
Sedimentological and palæontological data point to a shallow marine depositional environment.
The well-sorted nature of the unit suggests that it was probably deposited close to the shoreline, in a high energy environment. This is backed up by the absence of clay-sized particles, and the rounded, spherical shape of quartz grains.
Features, such as the presence of coal beds and desiccation cracks, suggest that parts of the unit were deposited subaerially. Ripple marks and cross bedding show that shallow water was also commonly present.

Famous quotes containing the word environment:
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
