Abstract

The Falls Lake melange is a metamorphosed terrain composed of mafic and ultramafic blocks and pods of diverse shapes and sizes, dispersed without apparent stratigraphic continuity in a matrix of pelitic schist and biotite-muscovite-plagioclase-quartz-gneiss. Textural and structural relationships suggest formation by a combination of sedimentary and tectonic processes, perhaps in the accretionary wedge of a convergent plate margin. The Falls Lake melange and the overlying late Proterozoic to early Cambrian volcanic-arc terrain of the Carolina slate belt, were thrust upon a probable continental terrain of the Raleigh belt before overprinting by late Palaeozoic folding and metamorphism.-L.C.H.
