The town of Rockport was separated from Gloucester and incorporated in 1840. Granite was quarried here beginning in 1823. Interesting minerals occur in granite quarries and other bedrock exposures of alkaline Cape Ann granite and associated pegmatites and miarolitic cavities.
McKinstry (1921) described some of the town's mineralogical highlights: "More than fifty years ago attention was called to the unusual mineral occurrences at Rockport, on Cape Ann, by J. P. Cooke's description of danalite, a new beryllium mineral, and subsequently of cryophyllite, a new lithium mica. Besides being the type locality for these species, the Rockport quarries have afforded an interesting list of rare-earth minerals, and, perhaps most unusual of all, large tabular crystals of fayalite, normally an utter stranger to granitic rocks."
Foster, M. D and Evans, H. T. Jr. (1962) analyzed Rockport cryophyllite and determined that type material conformed to ferroan lepidolite.
M. RIEDER(CHAIRMAN), G. CAVAZZINI, Yu. S. D'YAKONOV, VSEGEI, Srednii, S. GUGGENHEIM, P. V. KOVAL, G. MOLLER, A. M, R. NEIVA, E. W. RADOSLOVICH, J.-L. ROBERT, F. P. SASSI, H. TAKEDA, Z. WEISS, AND D. R. WONES (1999)re-assigned lepidolite to a new species, trilithionite.
