Mineralia: (archaic, taxonomy) The taxonomic category for all non-life; that which is not life is a mineral.
A well known Connecticut locality for prehnite. Three varieties are found - standard green, rare yellow prehnite, and very rare white prehnite that is almost completely free of iron impurities. This one so rejected iron it made it sit on its surface in the form of tiny cubic pyrite.
Site closed to collecting in 2000.
