Summary:

Consists of well-bedded metasandstone, thinly laminated metasiltstone, and metashale. Thin medial unit of metalimestone. Thought to be fine-grained facies of Sangerville Formation and is assigned as a member (after usage of Pankiwskyj, 1979). About 1,000 m thick. Gradationally overlies Patch Mountain Member of Sangerville Formation. Age given as Silurian (late Llandovery to early Ludlow).

Summary:

Anasagunticook assigned to top of Waterville Formation. Underlies Sangerville Formation, which in the Buckfield area is divided into (ascending): Moody Brook, Berry Ledge, Noyes Mountain, Patch Mountain, and Turner members, replacing Buckfield Group. [Intent to revise the above units is not stated, but subdivision of the Sangerville and its lower contact are clearly shown in a stratigraphic column.] Order of younging within the sequence differs from reports of previous workers. Graded sequences suggest an inverted lithologic package. Rocks in this area were subjected to three deformational events. Age of Anasagunticook shown as Early Silurian.

Summary:

Anasagunticook Member reassigned from Sangerville Formation to Waterville Formation following usage of Osberg (1988). Not shown separately on this map to simplify nomenclature. Rocks previously mapped as Anasagunticook Member of Sangerville Formation in the Bryant Pond, Buckfield, Dixfield, and Farmington 15-min quads are here shown as Waterville Formation (queried). Anasagunticook correlated with Waterville by Osberg (1988) on the basis of lithologic similarity.
