The Imperial Formation is the name of two distinct and unrelated geologic formations in North America, of different geologic Eras.
Separate formations
[edit]Canadian Paleozoic Era formation
[edit]The older Imperial Formation occurs in the Northwest Territories of Canada. It preserves fossils dating back to the Devonian period of the Paleozoic Era.[1]
Californian Cenozoic Era formation
[edit]The younger Imperial Formation occurs in the Colorado Desert, in Imperial County of Southern California. It dates to the Zanclean−Lower Pliocene stage of the Pliocene Epoch, during the Neogene Period of the Cenozoic Era.
It underlies the Palm Spring Formation, and overlies the Ocotillo Formation.[2]
