Major:: {quartz diorite},Minor:: {tonalite},Incidental:: {granodiorite, granite}

Spaulding Tonalite (Spaulding Quartz Diorite of Fowler-Billings, 1949) - Weakly foliated to nonfoliated, spotted biotite quartz diorite, tonalite, granodiorite, and granite; garnet and muscovite may or may not be present.

Part of the New Hampshire Plutonic Suite (Late to Early Devonian) - Includes synkinematic and postkinematic granitoids related to the Acadian orogeny. Ages range from 410 to 365 Ma. New Hampshire Plutonic Suite: Kearsarge pluton = 393+/-5 Rb/Sr per NH028. Blackwater pluton = 398+/-? U/Pb, monazite per NH030. Pratt Pond pluton = 280+/-6 U/Pb, zircon, 272+/-2 U/Pb, monazite (J.N. Aleinikoff, oral commun., Dec. 1994). 365+/-? U/Pb, zircon, 365+/-? U/Pb, monazite (J.N. Aleinikoff, oral commun., May 1995). Quartz syenite dike (point within formation) = 159 K/Ar per NH037.
