Maniwaki occurrences, Lac-Pythonga, La Vallée-de-la-Gatineau RCM, Outaouais, Québec, Canada
Cute little specimen of yellow stilbite, from the Maniwaki occurrences.
Two interpenetrant lustrous dark brown, wedge-shaped titanite crystals. The larger one is 4.5cm x 4cm The smaller one on top 2.5cm x 2cm A mass of diopside crystals grow on one side where they intersect. The two small 3mm. white squares are scapolite.

Very well terminated scapolite crystal from the Maniwaki region. Some orange calcite (sorry about the glare) is on it and an unknown mineral on the bottom. Crystal size: 5.5 x 2 x 2cm
Large xl with smaller xls surrounding it. specimen size: 9x5.5 cm largest xl size: 2.5cm tall
Diopside crystals up to 2cm - Overall size 6x5x3cm - October of 2006 - From Phil B collection

The chabazite is on a K-feldspar matrix.

The acicular crystals are stilbite. The darker blocky crystals on the upper left is chabazite.
The white rectangular mineral are heulandite and the sheeves are stilbite on a matrix of K-feldspar.
This specimen was collected by my friend Jerry Van Velthuizen who described the locality in his paper on Zeolite localities in the Grenville. The matrix is looks like pyroxene.
This small thumbnail shows some orange chabazite crystals in a diopside matrix.
X marks the spot. This is a specimen of twinned stilbite-Ca crystals both of which are double terminated. As this is a small thumbnail it was very difficult to photograph.
