The Topic Is:
Pseudomorphs, Trickster Mineral Specimens

The word pseudomorph was first used by Hauy in 1801. In Greek it means “false shape” A pseudomorph is a mineral that has the external crystal shape of another mineral. The subject of pseudomorphs was first written about in detail by the 19th century German mineralogist Johann Blum. Pseudomorphs were later classified by the mineralogist Strunz in 1982. The talk covers the various theories of how pseudomorphs form. In some cases the second mineral is similar in composition to the original mineral. In those cases the mechanism is a chemical reaction. In other cases the two minerals are not similar and the mechanism of pseudomorph formation is more complicated. There is still controversy about the formation of some pseudomorphs. The talk is illustrated with pictures of both common and rare pseudomorphs.

Orange County Mineral Society is inviting you to a scheduled Zoom meeting.
