Fossil and Relative Age of Rock notes
... The relative age of a rock is its age compared to the ages of other rocks, it is like comparing your age to someone else’s. The relative age does not provide its absolute age The absolute age of a rock is the number of years since the rock formed; It is difficult for geologists to determine the ...

Mount Pleasant Caldera
The Mount Pleasant Caldera is a large eroded Late Devonian volcanic caldera complex, located in the northern Appalachian Mountains of southwestern New Brunswick, Canada. It is one of few noticeable pre-Cenozoic calderas, and its formation is associated to a period of crustal thinning that followed the Acadian orogeny in the northern Appalachian Mountains.It sits relatively near to the coastline.
