psephite
psephite A general term used to describe coarse-grained, detrital, sedimentary rock, e.g. gravels, conglomerates, or breccias. G. W. Tyrell (1921) suggested the term be restricted to metamorphosed conglomerates and breccias, a suggestion followed by many authors describing metamorphic rocks.
