This specimen of epidote with quartz came from the Andover Iron Mine in Andover, Sussex County, New Jersey.  Andover is not that far from the Franklin-Sterling Hill complex.  The Andover mines at one time even yielded a variety of yellow-fluorescing willemite!  This makes a person wonder what else might lie deep beneath the rocks of Sussex county.  Epidote is a complex silicate of calcium, iron and aluminum.  It is in the same group as allanite and clinozoisite, as well as a bunch of much rarer species.
