Lithology and environment
| Primary lithology: | glauconitic conglomeratic sandstone |
| Environment: | shoreface |
| Geology comments: According to Roy (1984): "The siltstone at the head of the Rio Grande Embayment is interpreted to have been deposited in a shoreface environment. Grain size increases upward in the section with a concurrent decrease in clay content. Numerous scour channels indicate deposition at or near wavebase in a nearshore environment. Paleontological evidence, particularly the change in burrows, suggests an environmental change that would occur from the transition from offshore to nearshore." The basal conglomeratic sandstone is consistent with a shoreface at the beginning of transgression. | |
