This field trip will focus on the petrology and structure of basement-cored anticlines in the central Appalachian Piedmont, near Baltimore, Maryland (Figure 1). These structures have long been interpreted as mantled gneiss domes in the sense of Eskola (1949). However, recent work suggests that they are recumbent nappes, arched by later folding about steeply dipping axial planes.GneissGneiss.552.4Fisher George W993128PQKBBOOK996217165203316Petrology and Structure of Gneiss Anticlines near Baltimore, Maryland2274092UNISA
