The January-February (vol. 37, # 1) did a fantastic job of showcasing the minerals of the Francon Quarry in Montreal, Canada.  An entire issue totally devoted to this important locality and its minerals!  They even went as far as to reprinting some images needing color corrections in the next issue.  "Nice job Min. Record."

"The Francon Quarry ranks as the second most prolific type locality in Canada after Mont Saint-Hilaire.  It has yielded ten new mineral species: weloganite, dresserite, hydrodresserite, strontiodresserite, sabinaite, franconite, doyleite (co-type locality), hochelagaite (co-type locality), montroyalite and voggite.  Weloganite, described in 1968, established the quarry as a world-famous mineral collecting site.  Weloganite was the first known zirconium carbonate, and remarkably, it occurs as attractive, well-formed crystals up to 6 cm in size.  Ninety species have been documented from the quarry, mostly from unique, dawsonite-rich carbonatized phonolite sills which are genetically part of the Monteregion Hills alkaline igneous province." (Tarassoff, et. al., 2006)

Now that the quarry has been filled (with trash!) and is no longer open to collectors, where does one acquire these fine and rare specimens?  I have seen a few on the internet...always, SOLD.  Thanks to the fine collecting efforts of Dr. Steve Chamberlain we now have a fantastic assemblage of Francon minerals.  His 15 years of work are shown here in what amounts to the finest selection of Francon Quarry minerals to be found for sale, anywhere!  Add one or more to your collection quickly.  There will be no more of these rare specimens available in the future.

***IMPORTANT NOTES***    Many of these specimens contain additional minerals which are not listed in their descriptions.  Only the macro-crystals are noted so any other minerals found under closer inspection can be considered nice bonuses.  Also, the white coating found on many of the weloganites is most likely Franconite.  The weloganite from Francon fluoresces under S.W., M.W. and L.W. ultraviolet light.  It is also pyroelectric and triboluminescent (emitting bluish-white flashes when fractured).

OKF-364

OKF-364    Weloganite    Upper Sill, Francon Quarry, Montréal, Québec, Canada.  Ex Dr. Steve Chamberlain collection.  This is probably the largest weloganite crystal to come from Steve's Francon quarry collection.  The primary crystal measures 3.9 cm has been reattached to the nicely trimmed section of matrix.  The lower termination has a small area of attachment but the rest of the crystal is very clean.  The backside of the crystal is open to the vug is contained within.  So even though it looks to be embedded in its opening, it sits up nicely outside of it for viewing.  If this crystal was slightly better formed it would be a museum great specimen.  Because it is somewhat crude I have a bargain basement price on this extremely rare piece.  Weloganite crystals are almost never this large and very seldom on matrix.  Very desirable, displayable and rare.  $450

OKE-373    Weloganite    Francon Quarry, Montreal, Quebec, Canada.  Ex. Steve Chamberlain Collection.  Great Mineralogical Record issue dedicated to this now permanently closed locality (Ref. Min. Record Jan- Feb. 2006, Vol # 37, No. 1).  Exceptional specimen in all regards…2.9 cm ranks this as very large for this rare species, which is from its type locality.  The luster, translucence and yellow color are all top of the line.  This particular crystal is the largest I have ever owned and the only one I would describe as being double terminated.  There is a tiny contact on one termination where it may have been loosely connected to matrix.  Minor white coating is likely Franconite (also type locality for the species).  Amazing single crystal with a couple of very tiny rider crystals.  Specimen has more of a yellow color than the photo indicates.  One of the finest TN specimens I have ever owned.  600$

 

 

 

 

 

 

OKE-374

OKE-374    Weloganite    Francon Quarry, Montreal, Quebec, Canada.  Ex. Steve Chamberlain Collection.  Great Mineralogical Record issue dedicated to this now permanently closed locality (Ref. Min. Record Jan- Feb. 2006, Vol # 37, No. 1).  WOW!  These crystals always seem to be a small crystal with a huge chunk of non-trimable matrix or with no matrix at all.  This is one of only a couple I have ever seen which has large crystals and minor (just the right amount) of matrix.  There are several large crystals here, to 1.6 cm each in crude parallel growth.  Rare growth zoning and unknowns here too.  Small clear crystals on the weloganites and tiny black spots that are who knows what.  Specimen has more of a yellow color than the photo indicates.  Piece measures 2.7 x 2.7 x 2.1 cm.  Zero damage.  Amazing TN specimen!  575$
