“…A possible scenario is that the inferred crustal shear zone that corresponds to the Acadian suture extends across much of Connecticut, and its geometry has been altered or displaced by younger tectonic events. For example, the hypothesized collapse of the Acadian altiplano involving orogen‐parallel escape (Hillenbrand et al., 2021; Massey et al., 2017) would have modified the crustal structure, perhaps altering the geometry of the inferred Acadian suture. Since a noticeable change of geometry occurs beneath Hartford basin, where the shear zone appears to shallow locally, we hypothesize that the localized extension during the Mesozoic rifting may have also played a role in altering its geometry.…”

“…The abundant ~385‐Ma detrital titanite grains may have been derived from different, more metaluminous units of the New Hampshire Plutonic Suite than those that supplied the monazites, although they might have also been obtained from appropriately aged plutons in Massachusetts in the Lowell area (Walsh et al, ). The small number of younger monazite grains around ~350 Ma may record the Neoacadian orogeny (Robinson et al, ), and domains of appropriate age have been observed in monazites in migmatitic gneisses in southwest New Hampshire (Pyle et al, ), along with other localities in central Massachusetts and Connecticut (Massey et al, ), further outside the drainage basin of the Merrimack River. The thermal imprint of this event may have also aided in producing the wide spread of Late Devonian and Carboniferous rutile ages.…”
