Liberty Complex of the Potomac terrane in MD consists of three units: the Soldiers Delight ultramafic complex, the Morgan Run Formation, and the Sykesville Formation. Soldiers Delight is composed of metamorphosed ultramafic rocks with lesser amounts of metagabbro and metapelite. Primarily a serpentinite with variable amounts of chlorite and actinolite. May be related to small ultramafic bodies in the Morgan Run.

Named for Soldiers Delight area, Reisterstown 7.5-min quad, Baltimore Co., northeastern MD. Previously called Soldiers Delight belt of serpentinite by other workers. Reference localities are two quarries along Piney Run, and outcrops and quarries along South Branch of Patapsco River in Sykesville 7.5-min quad. Mapped as a tadpole-shaped body along western margin of Baltimore terrane from Soldiers Delight to just northeast of Tridelphia Reservoir. Has been mapped in Reisterstown, Sykesville, Woodbine, and Sandy Spring quads. Outcrops are small and not abundant. Consists of ultramafite almost completely altered to serpentinite (probably originally peridotite, dunite, pyroxenite). Lies tectonically between Late Proterozoic and (or) Early Cambrian Loch Raven Schist and Early Cambrian Sykesville Formation. Other ultramafic rocks in Appalachian Piedmont are considered to be Late Proterozoic and (or) Early Cambrian because deformed bodies of this rock type occur within Lower Cambrian sedimentary melanges. Therefore, Soldiers Delight is considered Late Proterozoic and (or) Early Cambrian in age. Report contains geologic map and geochemical data.
