Summary
editDescriptionChromitic serpentinite (Soldiers Delight Ultramafite; chromite mine in the Bare Hills, Baltimore County, Maryland, USA) (14635729769).jpg |
Chromitic serpentinite from Maryland, USA. (5.2 cm across at its widest) Light green = serpentine Black = chromite Ophiolites are fragments of oceanic lithosphere (basaltic crust + uppermost mantle) that have been metamorphosed and plastered onto the edges of continental lithospheric plates by obduction (the opposite of subduction). The rock shown above is from the Soldier’s Delight Ultramafite, which represents metamorphosed upper mantle rock exposed in an ophiolite in the Maryland-Pennsylvania-Delaware Piedmont along America's eastern seaboard. Unit & age: Soldier’s Delight Ultramafite, lower Baltimore Mafic Complex, probably Neoproterozoic to Cambrian oceanic lithosphere, metamorphosed during the Taconic Orogeny (Late Ordovician-Silurian). Locality: unrecorded old chromite mine in the Bare Hills, north of Baltimore city limits, Baltimore County, northern Maryland, USA. |
