Oxford pegmatite field.
A quarry in granite pegmatite best known for the reportedly 80-foot-long "Mother Mary Pocket" mined by Frank Perham and crew during August 2017, which contained many sceptered quartz crystals.
Observed on the May 19, 2024, New England Mineral Conference field trip were many boulders of the pocket collapse breccia that was situated below this pocket (both zones were already excavated by this time). The breccia consists of chunks of albite/cleavelandite, quartz, and spodumene replaced by muscovite, all cemented by a fine-grained, olive green secondary muscovite. Coarse-grained, replaced cleavage fragments and pseudomorphed crystals of spodumene with a similar green color and waxy luster to 20-30 cm are abundant in breccia boulders. White masses of parallel-growth, fine-grained albite, some of it etched and porous, are also present, as are small pockets lined with yellow-green muscovite and quartz plus quartz in veins. Some of the milky quartz crystals in the pockets and veins are sceptered by clear, smoky overgrowths. Coarse-grained, white cleavelandite masses and muscovite border the breccia. The rest of the pegmatite exhibits fairly common accessory mineralogy, with schorl and almandine being the most abundant.
