State	Maine
Name	Ordovician - Precambrian Z Cape Elizabeth Formation

Comments	Divisible into lower member of black to dark-gray, thinly laminated carbonate shale and minor feldspathic quartzite, 2,000 m thick and upper member of gray, thinly laminated shale and siltstone, 600 m thick. Underlies Albee Formation. Used in ME and NH as far east as 70 deg 45' at east edge of Cupsuptic quad; Dead River Formation is eastward equivalent of Aziscohos and Albee Formations. Age is Early Ordovician. (ME041)
