Wavellite

Wavellite is a well-known phosphate mineral, often recognized for its radiating crystal formations. This small cabinet specimen features flattened Wavellite clusters, which have grown within a tight crevice in the host rock. It originates from Mauldin Mountain, Arkansas, a classic locality for fine Wavellite specimens.

The specimen comes from two adjacent road metal quarries—one state-owned and the other county-owned—situated on the south side of Mauldin Mountain in Bigfork Chert. This region is renowned for producing Wavellite in varying shades of green, often displaying a silky luster and radial crystal habit.

This specimen comes from the collection of Dr. Peter Tarassoff, a prominent figure in mineralogy, particularly known for his work at Mont Saint-Hilaire (MSH). His diligent collecting and examination efforts have led him to be the first to identify at least 35 species and discover 12 new species, not only at MSH but also at other alkaline localities. Dubbed the "Dean" of Mont Saint-Hilaire collectors, Peter was honoured with the naming of the new species petarasite in 1980. He has authored or co-authored numerous mineralogical articles and has been a member of the Mineralogical Association of Canada since 1964. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years, where he was formally appointed the Honorary Curator of Mineralogy. In recognition of his significant contributions to mineralogy, Peter was awarded the 2017 Pinch Medal
