Petrology and structure of gneiss anticlines near Baltimore, Maryland. Field trip guidebook / Петрология и структура гнейсовой антиклинали возле Балтимора, Мэрилэнд. Путеводитель полевой экскурсии

However, recent work suggests that they are recumbent nappes, arched by later folding about steeply dipping axial planes. <...>
