Nanaimo Geology

A great area and day to look at rocks:

Richard and I worked with Professor Brian Coffey looking at the sediments of the Upper Cretaceous Nanaimo Group on Vancouver Island in addition to Mississippian to Pennsylvanian carbonates (359.2 ± 2.5 to 299 ± 2.5 Ma = million years old) further inland (2004-05).

The Upper Cretaceous Nanaimo Group (93.5 ± 0.8 Ma to 65.5 ± 0.3 Ma) are dominated marginal marine, marine and submarine deposits. The rocks of the Nanaimo Group were later deformed in several pulses between the Eocene and the Miocene (55.8 ± 0.2 to 5.332 ± 0.005 Ma).

I am in the hat... Brian snapped the photo.
