The mica schist started out as clay rich mud in a marine basin that probably formed during the early Acadian Orogeny.
In the case of negative topography (i.e., a marine basin), the balancing of lithospheric columns gives:
They were deposited in the late Miocene in deltas and near-shore shallow marine basins.
The upper Baraga Group represents deeper marine basins resulting from increased subsidence and continued collision.
The formation of a salt dome begins with the deposition of salt in a restricted marine basin.
Depositional sequences have been thoroughly studied by oil geologists using geophysical profiles of continental and marine basins.
In continental arcs the back-arc region is part of continental platform, either dry land (subaerial) or forming shallow marine basins.
Zeolites also crystallize in post-depositional environments over periods ranging from thousands to millions of years in shallow marine basins.
This broad depression was a seaway that connected the marine basin in California with that in east central Oregon.
Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins.
