In tectonic rock cycles, tectonic rock classifications replace descriptive rock classifications and focus on rocks characteristic of major tectonic regimes, such as the igneous-fractionation regime at convergent plate boundaries, quartz/feldspar/lithic (QFL) sedimentary distributions, and major metamorphic temperature/pressure fields. The tectonic rock cycle can be thought of as beginning with two igneous-fractionation processes generating all major igneous rocks at divergent and convergent plate boundaries. Weathering/erosion of subduction-generated volcanic arcs produce lithic-rich sediments. Arkosic to quartzitic sediments come from weathering/erosion of the batholithic (proto-continental) core of the volcanic arc. These processes generate the QFL end-member clastic sediments, which are spatially separated in the rock cycle. Carbonates are associated with quartz...

During four all-day field trips, upper-level geoscience majors visit outcrops along two transects running from the Blue Ridge Province in the east, across the Valley and Ridge province, to the Allegheny Front in the west. On each field trip, students work in two or three person teams to collect stratigraphic and structural data that provide information about regional Appalachian tectonics. Students use this field data to draft cross-sections that highlight plutonic, volcanic, metamorphic, and in particular the stratigraphic sequence and structural deformation that characterize the tectonic history of the Mid-Atlantic region over the past billion years. Example cross-section and outcrop-scale exercises highlight specific components of the project. Students complete the project with a tectonic synthesis of the region that interprets depositional and deformation features within the context of theoretical models.
