...WALLACE A. BOTHNER Abstract The Exeter diorite pluton of southeastern New Hampshire is a small mesozonal batholith emplaced into asymmetrically folded Silurian metasedimentary rocks. The body produces a positive Bouguer gravity anomaly in excess of 16 mgals. The gravity maximum is located northwest...
