Summary:

Pg. 19, geologic time scale (inside front cover). Lucerne Granite of Wing (1958). Sample from coarse-grained quartz monzonite, at north end of Phillips Lake, Orland quadrangle, Hancock County, Maine, yielded U-Th-Pb ages from 380 +/-4 Ma to 269 +/-3 Ma. Age of Lucerne Granite considered to be about 380 Ma [Devonian]. Ages calculated using decay constants of Steiger and Jager, 1977 (Earth Planet. Sci. Letters, v. 36, p. 359-362).
