This specimen features a velvety jet-black cleavable mass of "Barkevikite", accompanied by feldspar and coarsely crystallized nepheline. Dr. Peter Tarassoff acquired this rare mineral from John Albanese in New Jersey back in 1964. Minerals of this type are quite rare globally, adding significant value and historical importance to this piece.

Barkevikite is an obsolete name (discredited in 1978) for an occurrence of Ferro-edenite from pegmatitie formations in the eastern part of the Langesudsfjord area of Norway. Ferro-edenite is a fairly rare member of the Calcic Clino-Amphibole Subgroup of the Amphibole Group of minerals that includes Actinolite, Ferro-edenite, Kaersutite, Pargasite, Richterite and Tremolite. The Amphibole Group is an extensive and complex group of minerals currently divided into several sub-groups. Ferro-edenite is almost identical to the more common Amphibole mineral Edenite but contains more iron than magnesium, thus the name Ferro-edenite (ferro is Latin for iron). Ferro-edenite is generally darker and more dense.*

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.
