Outcrops of four metamorphic formations occur along the eastern boundary of Jefferson County in the eastern panhandle. The Precambrian metaigneous Catoctin greenstone consists of metamorphosed basalt lava flows. Three Lower Cambrian metasedimentary formations include (from older to younger) the Weverton quartzite (a metamorphosed sandstone), Harpers phyllite (a metamorphosed shale), and Antietam quartzite (a metamorphosed sandstone).
