Meta-Autunite

This is an excellent specimen of meta-autunite from the renowned uranium-producing Daybreak Mine in Washington. The specimen exhibits the characteristic yellow-green hue, with foliated, platy orthorhombic crystals covering both sides, the largest reaching 17 mm. It exhibits intense neon green fluorescence under UV light. Mined in the 1950s and 60s, specimens from this active period are now quite rare, especially those as dense and colourful as this one. This specimen comes from a classic U.S. locality for radioactive minerals, the Daybreak Mine is the type locality for meta-autunite, adding historical and mineralogical significance to this already stunning display piece.

Note for international customers: This specimen is radioactive. Please ensure your country permits the import of such materials before ordering. Contact me in advance with any specific shipping questions or concerns.

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.
