Devonian Parker Bog Formation (MEDpk;0)

State	Maine
Name	Devonian Parker Bog Formation
Geologic age	Devonian
Lithologic constituents	Major Sedimentary > Carbonate > LimestoneGS - Greenschist facies; Protolith N - Limestone and/or dolostone Igneous > Volcanic > Felsic-volcanic (Pyroclastic-tuff)GS - Greenschist facies; Protolith N - Limestone and/or dolostone
Comments	Named for Grand Lake Matagamon. Type section is on west slope of Hay Mountain, north of Grand Lake Road (southeast of Grand Lake Matagamon). Occurs in the area southeast of Grand Lake Matagamon to the area around Hay Lake and Atwood Pond in the Traveller Mountain and Shin Pond 15-min quads, Penobscot Co., northern ME. Consists of medium bluish-gray or greenish-gray, fine-grained, slightly calcareous, thickly bedded, rusty weathering sandstone; also includes minor amount of dark slate and argillaceous siltstone interbedded with sandstone. Terrane is characterized by low hogback ridges. Thickness estimated between 4,000 to 5,000 ft. Conformably underlies Traveller Rhyolite of Toppan (1932) (contact is gradational). Report includes geologic map. (ME013) Unit description from USGS GEOLEX website (ME078). W - Weakly metamorphosed; contains local occurrences of prehnite and pumpellyite; Protolith F - Quartz sandstone.
