Summary:

(J.B. Hadley, 1938, Geologic map and structure sections of the New Hampshire portion of the Mt. Cube quadrangle).
Baker Pond gneiss in Oliverian magma series. Fine-grained gray gneiss, locally containing microcline phenocrysts. Largely quartz monzonite with some granodiorite. Border phase is dark-greenish-gray quartz diorite gneiss. Included in Oliverian magma series whose age is younger than Lower Devonian and is probably Upper Devonian. [Age of Oliverian Plutonic Suite has since been changed to Middle Ordovician.]
Mapped in the area around Upper Baker Pond, which is located on the border of the Mount Cube and Rumney quadrangles, west-central NH.
