Heulandite

Welcome to the Street Prophets Coffee Hour cleverly hidden at the intersection of religion and politics. This is an open thread where we can share our thoughts and comments about the day. Let’s look at some Heulandite from Idaho.

Heulandite is the name given to a series of tecto-silicate minerals of the zeolite group. Zeolite minerals boil in blowpipe heat and the name, zeolite, is from the Swedish zeolit meaning “boiling stone.”

Heulandite, by the way, is named for the nineteenth-century mineral collector Henry Heuland.

The heulandite shown below was displayed in the Northwest Mineral Gallery of the Rice Museum in Hillsboro, Oregon.
