Abstract

The Kittery Formation is a Silurian- to Ordovician-age metasiltstone and metapelite sequence that spans from the coast of southern Maine into northern coastal Massachusetts. The Cape Neddick Gabbro is a Cretaceous- to Jurassic-age igneous body, believed to be the magma chamber of a Paleozoic volcano, that intrudes the Kittery Formation near York, Maine. During the emplacement of igneous bodies at depth, contact metamorphism of the surrounding country rock occurs, given the high temperatures produced by the intrusion, and the increased pressures at depth. For this project, the conditions of metamorphism that the Kittery Formation underwent were estimated using mineralogical, petrological, and chemical analysis techniques. My results suggest that the Kittery Formation underwent low-pressure, high-temperature metamorphism.
