Ames Monzodiorite of White Mountain Plutonic-Volcanic Suite (NH)
Ames Monzodiorite in /White Mountain magma series [informal] (NH)
[When referring to the White Mountain magma series of Billings (1934), please use informally. The practice of employing "Series" for lithostratigraphic or lithodemic nomenclature is now regarded as improper (ACSN, 1961, 1970; NACSN, 1983, 2005). The term "Series" is applied formally only to chronostratigraphic units.]
Late Triassic to Early Cretaceous
Notable exposures on shore of Lake Winnipesaukee, northwest of Ames Station, in Belknap Mountains, south-central NH (US geologic names lexicons, USGS Bull. 896, 1200).
