This specimen has maybe the most dresserite I've ever seen filling the inside of a vug, accompanied by numerous grey weloganite crystals. Dresserite is an incredibly rare barium aluminum carbonate species found only in the alkalic sill of limestone at the Francon Quarry. Named after Canadian geologist John Dresser in 1968, the species honors his significant contributions to the knowledge of the Monteregian Hills, where the Francon Quarry is located. This specimen was collected by Dr. Tarassoff in 1995, specimens of this quality and rarity are increasingly uncommon, highlighting the exceptional nature of this particular find. The quarry ceased operations in 1981 and will never reopen, making specimens from this location particularly valuable to collectors.

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.
