We begin our journey through the Mesozoic Sierran arc with an examination of the Guadalupe Igneous Complex, a layered Jurassic pluton that intrudes into largely oceanic materials in the Foothills Terrane of the Western Metamorphic belt (Figs. 1-1 and 1-2). The Guadalupe Igneous Complex is an intuitively pleasing target to begin with because of its outboard (western) location and because it consists of some of the most mafic (>8% MgO gabbros) and felsic (high-silica and high-K2O granophyres and rhyolites) igneous units that we will see on this trip and thus raises some longstanding petrologic questions about the connections between mafic and felsic granitoids in arcs. It is also an exciting objective because of the preservation of its likely feeder zone (the Hornitos pluton), internal layering, and capping volcanics (Fig. 1-2)…
