Subdivision of the Cretaceous system
according to the ICS, as of 2017.[1]

The Early Cretaceous (geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 146 Ma to 100 Ma.

Geology

A large igneous province on the Liaodong Peninsula, China, c. 131–117 Ma lasted for 10 million years. It was the result of the subduction of the Kula and Pacific plates, which was probably caused by a superplume.[2]

During the opening of the South Atlantic the Paraná–Etendeka large igneous province produced 1.5 million km³ of basalts and rhyolites per year beginning 133 Ma and lasting for a million years.[3]
