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).

 

 

 

 

OKD-721

Weloganite close up

OKD-721   Weloganite, Calcite, Quartz, Dawsonite and Franconite      Francon Quarry, Montreal, Quebec, Canada.  Ex. Dr. Steve Chamberlain Collection.  13 x 8 x 4 cm plate with an 8 x 5 cm vug dominating the face of the specimen.  Within the vug is a fine collection of rare minerals.  The weloganites are most noticeable and noteworthy.  The are mostly yellow with white bands of franconite.  The largest of these is 1.4 cm in length.  Very contrasting forms to the largest of the two crystals.  Damage free minerals except for some edge contact and a small dome of crystal that is missing.  Some of the quartz and dawsonite are inside the lower section of the vug and not visible in the photographs while others are.  A large 2.5 cm quartz blocks much of the lower section of the vug.  Displays well.  A fine, interesting and rare classic.  380$

OKD-722    Weloganite, Calcite, Franconite and Cryolite      Francon Quarry, Montreal, Quebec, Canada.  Ex. Dr. Steve Chamberlain Collection.   Exceptionally clear weloganites which range from light yellow to colorless and gemmy cryolite crystals.  Blocky matrix measuring 7 x 6 x 6 with a vug of approx. 4.5 x 3 cm.  Weloganites are .3 to .5 cm and the cryolite crystals are up to .3 cm each.  Although the crystals are small, this is an excellent suite of rare and desirable minerals in excellent crystal form.  Displays well.  170$

Celestine

Galena? I think sphalerite.

OKD-723    Galena, Celestine and Quartz      Francon Quarry, Montreal, Quebec, Canada.  Ex. Dr. Steve Chamberlain Collection.  The vug which dominates this specimen is lined by micro quartz.  On the left is a large spray of celestine (approx. 1 cm) and on the right a metallic crystal of what has be said to be galena.  I think this is actually sphalerite.  6.5 x 5.5 x 5 cm.  Displays well.  80$

 

 

 

 

 

 

OKD-725

Dresserite

OKD-725    Dresserite, Quartz and Weloganite      Francon Quarry, Montreal, Quebec, Canada.  Ex. Dr. Steve Chamberlain Collection.  This is one of the finest displayable dresserite specimen I have seen.  A triangular specimen measuring 5.7 x 5 x 2.5 cm which has nice large balls of dresserite to 4 millimeters.  They are all over this specimens as singles and in small clusters.  There looks to be three balls of dresserite missing, otherwise no damage.  The quartz are tiny yet nicely formed and clearer than usual.  The weloganites are often hollow and white due to coatings of franconite.  This is a fine specimen with the dresserites being the most noteworthy of the minerals on this piece.  The two best groupings stand very high off the matrix.  A fine example of this and other rare minerals.  350$
