Arsenatian Vanadinite ("Endlichite"), Calcite, Limonite

Los Lamentos, Chihuahua

Dimensions: 7.0x3.3x3.4 cm
Price: CA

$80.00

"Endlichite" is an outdated name for arsenic bearing vanadinite where it forms a solid solution series between vanadinite and mimetite, with arsenic increasingly replacing vanadium. This rare secondary mineral results from the oxidation of primary lead minerals like galena and typically precipitates from aqueous solutions in veins and cavities alongside other secondary lead minerals. This specimen, from the Ahumada portion of the mine, features lustrous brown, tapering hexagonal prisms of endlichite on crystallized calcite, encrusting both wulfenite and limonite. The areas adjacent to the terminations of the endlichite crystals are reddish-brown and translucent, adding to the aesthetic appeal. Acquired by Dr. Tarassoff in 1959, this piece represents a classic and beautiful example of endlichite.

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.
