KUP10-1  Kupletskite on Aegerine  $125

Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

4.0 cm x 2.5 cm x 1.3 cm;  Kupletskite crystals to 5 mm

Coppery, coffin-shaped Kupletskite (K,Na)3(Mn,Fe)7Ti2Si8O26(OH)4F crystals are liberally scattered on black Aegirine (NaFe3+Si2O6) with a bit of white Albite.  In addition, there are some puzzling sprays of bronze-black needles.  At first I thought they might be the acicular habit of Kupletskite, but they taper to points.  After spending some time with the microscope, I'm beginning to think they are Aegerine. The bottom photo was an attempt to show how one of the Aegerines seems to be composed of many smaller crystals, some of which are diverging from the main branch and terminating in the same sort of bronze-colored points that can be seen in the sprays.

LF8-2  Leifite on Polylithionite and Rhodochrosite  $100

Poudrette quarry, Mt Saint-Hilaire, Québec, Canada

2.4 cm x 2.5 cm x 1.4 cm

Leifite ((Na,H2O)Na6[F2|Be2Al2(Al,Si)Si15O39],) is quite rare, found in half a dozen localities, of which Mont Saint-Hilaire produces the finest specimens.  This thumbnail Leifite fluoresces pale yellow-orange under LWUV.  The matrix contains minor Rhodochrosite (MnCO3) and Polylithionite (KLi2Al[(F,OH)2|Si4O10]), the latter of which fluoresces yellow under SWUV.  The future of Mont Saint-Hilaire is uncertain; it is possible that no more specimens will be coming out.

Demix Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

5.5 cm x 3.5 cm x 3.6 cm

A fine cluster of Monteregianite-(Y) ((Na,K)6(Y,Ca)2Si16O38·10H2O, see right photo) crystals, relatively large for the species, from the type locality.  They are so large for Monteregianite (about 2.5 mm), that they are even somewhat appreciable without a microscope or loupe.

collected 1992; ex Ron Waddell; ex Tom Fitzpatrick

3.7 cm x 3.5 cm x 2 cm

The cluster of 5 Burbankite : (Na,Ca)3(Sr,Ba,Ce)3(CO3)5 crystals is indicated by the blue and yellow arrows, and can be seen in the upper right photo.  They are naked-eye visible, but a loupe or microscope will enhance enjoyment of this specimen.  The yellowish Zircon (ZrSiO4) crystal (bottom two photos) is on the front edge of the specimen.  The handwritten card is from Ron Waddell.

ELP10-1  Elpidite on Albite  $32 RESERVED
ex Ron Waddell; ex Tom Fitzpatrick

Demix Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

4.5 cm x 4.3 cm x 2.5 cm

The Elpidite (Na2ZrSi6O15·3H2O) on this piece was checked by the National Museum of Canada in Ottawa.  It is a somewhat different habit than usual, the blades being shorter and more translucent. Although the clusters are naked-eye visible, a loupe or microscope would enhance enjoyment of this specimen.  The Elpidite fluoresces green and the Albite matrix fluoresces red under SWUV.  The handwritten card is from Ron Waddell.

Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

4.5 cm x 4.1 cm x 3.2 cm

Masses of Rhodochrosite (MnCO3) blades are partially coated by a gray-white mineral. Glassy Polylithionite (KLi2Al(Si4O10)(F,OH)2) sheets and a few cubes of Fluorite (CaF2 - bottom row of photos) complete the ensemble.  The Rhodochrosite and Polylithionite are naked-eye visible, but a loupe or microscope is required for the Fluorite.  The handwritten card is from Ron Waddell.

Silvery sheets of Polylithionite (KLi2Al(Si4O10)(F,OH)2) with a few stick-like Aegerine (NaFe3+Si2O6) crystals.  The Polylithionite is yellow under SWUV.  The handwritten card is from Ron Waddell.

ex Ron Waddell; ex Tom Fitzpatrick

Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

4 cm x 3.5 cm x 3.5 cm

Fuzzy white Hochelagaite ((Ca,Na,Sr)(Nb,Ti,Si,Al)4O11·8H2O, see middle row of photos) in association with colorless blades of Ancylite-(Ce) (SrCe(CO3)2(OH)·H2O). The blue arrow in the lower right photo is pointing at one of the Ancylite-(Ce) blades.  The photo at lower left shows more Hochelagaite and Ancylite.  The clumps of Hochelagaite are easily naked-eye visible (see top left photo), but to appreciate their fuzziness and to see the Ancylite, a loupe or microscope is required. The handwritten card is from Ron Waddell.

CHLOR10-1  Chlorite Group mineral, Mica and Calcite  $28
collected 1984; ex Ron Waddell; ex Tom Fitzpatrick

Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

4.3 cm x 3.3 cm x 2.5 cm

Here we have tan rosettes of a Chlorite group mineral interspersed with black books of Mica. The Chlorite group minerals most common at Mont Saint-Hilaire are Clinochlore ((Mg,Fe2+)5Al(AlSi3O10)(OH)8) and Chamosite ((Fe2+,Mg)5Al(AlSi3O10)(OH)8), and they do commonly occur in brown.  Nice white Calcites provide a contrast.  Although the constituent minerals are easily naked-eye visible, a loupe or microscope is required to see how the rosettes are formed.  The handwritten card is from Ron Waddell.

2.8 cm x 2.7 cm x 1.6 cm

Radiating starburst of red Pyrophanite (Mn2+TiO3) crystals, close-up in lower left photo, and a rosette visible edge-on in lower right photo.  The rosette is in a vug, so I was not able to orient the Dino-Lite for a better photo, but even the edge is kind of cool.  You definitely want a loupe or microscope for this specimen.   The handwritten note is from Ron Waddell.

ex Ron Waddell; ex Tom Fitzpatrick

Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

6.3 cm x 4.8 cm x 4.0 cm

Two opaque, white Griceite (LiF - see both lower photos) crystals on a pile of tan, glassy crystals that Ron Waddell thought were probably from the Lovozerite Group, accompanied by dark red Villiaumite (NaF - in the background of the lower left photo).  The naked eye can just barely spy the two Griceites thanks to their remarkable whiteness, but a loupe or microscope will show more detail.  Mont Saint-Hilaire is the type - and the only - locality for Griceite, and these are nice specimens of this rare species.  The handwritten card is from Ron Waddell.

Gray-brown disc-like Synchysite-(Ce) : Ca(Ce,La)(CO3)2F, singly and in groups, on Albite-Siderite matrix.  The Synchysite-(Ce) is sprinkled with tiny Pyrites and an unknown mineral in the form of white balls.  A loupe or microscope is required to really enjoy this specimen.  The handwritten card is from Ron Waddell.

collected 1963; ex Ron Waddell; ex Tom Fitzpatrick

Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

2.7 cm x 1.1 cm x 1.6 cm

This piece is the earliest collected of any in this update - just 4 years after quarrying began at Mont Saint-Hilaire. Tabular gray hexagons of Synchysite-(Ce) (Ca(Ce,La)(CO3)2F) are decorated with pyrite on their edges, as can be seen in the photo to the right.  A loupe or microscope is required to really enjoy this specimen, though the masses of Synchysite are readily visible without aid.  The handwritten card is from Ron Waddell.

collected 1987; ex Ron Waddell; ex Tom Fitzpatrick

Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada

2.9 cm x 2.3 cm x 2 cm

This is the best Gaidonnayite (Na2Zr(Si3O9)·2H2O) specimen I have ever owned - the crystals are large and numerous with completely wacky crystallography (bottom left photo and the yellowish rosette in bottom right photo).  If that weren't enough, the Nenadkevichite ((Na,Ca,K)(Nb, Ti)Si2O6(O,OH)·2H2O) is abundant and well-formed, too.  The red arrow (middle left photo) points at an example of Nenadkevichite that matches the drawing Ron Waddell did on the pink label on top right.  (The back of the pink label contains the Nenadkevichite XRD analysis number.)  Three other similar Nenadkevichite groups enhance the bottom right photo, which also features purple Fluorite (CaF2).  The middle right photo shows Rhodochrosite on Microcline.  A loupe or microscope is required to enjoy this specimen.

2.8 cm x 2 cm x 2 cm

A pair of Zircon (ZrSiO4) crystals on a matrix of Natrolite (Na2Al2Si3O10·2H2O).  Under SWUV, the Natrolite fluoresces green and the Zircon fluoresces yellow.   The Zircons are large enough for naked-eye enjoyment.  The handwritten card is from Ron Waddell.

2.7 cm x 2.7 cm x 2 cm

In the top left corner of the top left photo, there is a brownish vug that seems to contain all the crystals of interest on this piece. Brown needles of Yofortierite (Mn5Si8O20(OH)2·8-9H2O - see lower left and lower right photos) and a bright, sherry-colored, prismatic crystal of rare Vinogradovite ((Na,Ca,K)4Ti4AlSi6O23(OH)·2H2O) - visible in the lower right corner of the lower right photo).  A loupe or microscope is required to enjoy this specimen.  The handwritten card is from Ron Waddell.
