| Geology comments: Some sedimentologists have characterized the Pebble Point Formation as having been deposited in marginal rather than open marine environments, based on the presence of the foram Cyclammina. Yet, the common presence of echinoderms as well as nautilid cephalopods, both intolerant of salinity much higher or lower than open ocean values argues against this. While numerous clasts are present, other evidence suggests quiet sedimentation rather than high energy. Pebble Point Formation thought to have been deposited during a series of channeling and channel abandonment episodes. Mud rip-up clasts and mud drapes indicate times of channel abandonment. Shelly fauna mostly come from the upper half, which may represent a change from estuarine conditions to more open marine conditions. | |
