Item Description

Collinsite from this locality, according to Mindat.org, is said to have its origins in large deposits of guano, or bat poop. This is a classic find for the study of such origins, apparently. The collinsite here is in light brown, fibrous aggregates associated with fluorapatite on andesine. Also in association is "wurtzilite," now known as asphaltum, a natural hydrocarbon mineral more commonly referred to perhaps as "tarry goo." Interesting old label from the George White collection.
