Muscovite, Tourmaline
Pack Rat Mine, Mt. Tule, Jacumba District, San Diego Co., California, USA
Small Cabinet, 5.9 x 3.2 x 1.9 cm
A rare and strange pseudomorph specimen from the much less well-known Pack Rat Mine of San Diego County. Pearlescent muscovite blades have totally pseudomorphed a large tourmaline crystal. The pseudomorph is nicely attached to a shard of complimentary albite. It is a highly representative specimen of a rare pseudomorph. Older material from the Chuck Houser Collection.
