... was instead constructed on a Gondwanan-derived terrane preserved in the Moretown Formation, which we refer to here as the Moretown terrane. Metasedimentary rocks of the Moretown Formation were deposited after 514 Ma and contain abundant ca. 535–650 Ma detrital zircon that suggest a Gondwanan source...

.... The Chester Park Gneiss, now known to have detrital zircon age spectra which match the Gondwana-derived Moretown Terrane in New England, is also featured. The trip will examine contact relationships between arc and Laurentian rocks and a newly discovered location where metapelitic rock contains garnet...

... and hence east of the Red Indian Line ( Boone et al., 1989 ); the Moretown Formation is thought to be part of peri-Laurentian terranes and west of the Red Indian Line ( Stanley and Ratcliffe, 1985 ; Hibbard et al., 2006 ). We cannot answer all of the questions here. Our intent is to point out some...

... are the Rowe, Moretown, and Hawley slices ( Fig. 1 ), collectively referred to as the Rowe–Hawley Belt (RHB; Stanley and Ratcliffe 1985 ; Stanley and Hatch 1988 ). The Rowe slices of the RHB contain metamorphosed sedimentary rocks, greenstones, and ultramafic rocks that have been interpreted as part...

... Hill arc terrane in central New England. The chemical compositions of the rocks suggest that prior to metamorphism, they were tonalites, granodiorites, and granites ( Leo et al. 1984 ). The rocks studied here were granodiorites, as classified by both normative (60–64 wt.% SiO 2 ) and modal...
