This specimen features small yellowish-brown masses embedded in coarse-grained nepheline syenite, composed of feldspar, nepheline, and biotite. The mineral is a member of the Wöhlerite Group, a sorosilicate characterized by a unique crystal structure containing two topologically independent octahedral walls.

This particular piece was purchased by Dr. Tarassoff in 1977 from W. D. Christianson Minerals. The Wöhlerite Group minerals are relatively rare, and this specimen highlights their occurrence within nepheline syenite, a distinctive igneous rock.

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 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.
