Molybdenite

Seikyu Mine, Shimane Prefecture
Japan
Dimensions: 9.8x4.8x3.6 cm
Price: CA

This specimen features lustrous molybdenite crystals with a characteristic silvery-blue metallic sheen, set against a gray-brown matrix. The molybdenite exhibits a typical layered matrix structure. The specimen originates from the Seikyu Mine, a hydrothermal vein-type molybdenum deposit that was actively mined from 1954 until 1966.

Adding to its historical and scientific value, this particular piece was gifted to Dr. Tarassoff by Professor Yazawa and Professor Nambu of the Research Institute of Mineral Dressing and Metallurgy at Tohoku University in Sendai, Japan. The connection to these distinguished researchers highlights the specimen's significance, both as a mineralogical example and as a piece of academic history.

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 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, Peter 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.
