The Catoctin Formation is dominated by a series of Neoproterozoic basaltic lava flows that were later metamorphosed to greenstone during the late Paleozoic Alleghanian Orogeny. This sample was collected at Rockfish Gap, to be imaged in conjunction with these two outcrop scale GigaPans: https://viewer.gigamacro.com/view/BUs7kxQE18pvPmst https://viewer.gigamacro.com/view/1RDG4sAZvugTVYCb The hand sample is imaged perpendicular to the plane of foliation.
