Early Cambrian origin of the shelf sediment mixed layer

The timing of origin of the mixed layer, the zone of fully homogenized sediment resulting from bioturbation in modern oceans, is controversial, with estimates ranging from Cambrian to Silurian. Here, the authors show that a well-developed mixed layer was established in shallow marine settings by the...

Sumario:The timing of origin of the mixed layer, the zone of fully homogenized sediment resulting from bioturbation in modern oceans, is controversial, with estimates ranging from Cambrian to Silurian. Here, the authors show that a well-developed mixed layer was established in shallow marine settings by the early Cambrian.
