Wardite, Crandallite

Fairfield, Utah Co., Utah
Size: 4.9x3.9c3.5 cm


"Bluish fibrous banded spherulites ("eyes") and crusts of wardite, rimmed by concentrically banded yellowish to white to brown fine-grained crandallite. Colourless composite hexagonal micro crystals of carbonate-fluorapatite in cavities. Exchange with Harvard University Mineralogical Museum (C. Frondel), July 21, 1958."

Much of this material was collected in the late 1930s and subsequently sold in gift shops by places such as The Smithsonian and the National Museum in palm-sized slabs, which is the most common way collectors come across it. Making this piece a bit more special.


This specimen comes from the collection of 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 and the Mineralogical Society of America for over 30 years. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years. In recognition of his significant contributions to mineralogy, Dr. Peter Tarassoff was awarded the 2017 Pinch Medal by the Mineralogical Association of Canada.

Peter's dedication to systematic collecting, curating his collection, and maintaining an archive of detailed historical and scientific information has greatly benefited the mineral sciences community both in Canada and globally. All specimens from this collection come with the original P. Tarassoff collection label.
