The rock sequences thereby created are known as the Keweenawan Supergroup.

Discriminating between an intrusive sill and a lava flow in ancient rock sequences can be difficult.

The name 'Triassic' comes from the way that some rock in Europe is arranged: called a "rock sequence."

The rock sequences of the Sydney Basin have undergone only a little folding and faulting since they first formed.

Later the sediments covering the rifts hardened into rock, forming layers of rock known as rock sequences.

The rock sequences have been studied by many geologists in the 19th and 20th century.

The same or similar rock sequences occur across the wider northwest European chalk 'province'.

The duration of diatom species ranges have been documented through the study of ocean cores and rock sequences exposed on land.

It is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas.

This collision zone has accommodated huge amounts of crustal shortening as the rock sequences slide one over another.
