Trottier quarry is an informal name, it may not have an official one. In 2007 & 2008 the quarry was owned by Luc Langlois of Les carrières Saint-Ferdinand. This is a more chalky dolomite marble.



Extract from the website of the MRNF (Quebec's Department of Mineral Resources and Fauna) :

The quarry was opened by Graybec in 1989; later, Les carrières Saint-Ferdinand acquired the property, and started its operations, in 2004.

The geological description reads as follows :

Oakhill Group dolomite (White Brooke Formation), varying from a very light gray to a bluish gray, sometimes pale brown, violet, greenish, or red. There are two dolomite levels, obviously tectonized (folded or knobbed), separated by fragments of chlorite schist, of laminated finely grained sandstone, and by thin beds of conglomerates of 2-4 mm quartz grains.

There are quartz veins to 40 cm (16 inches), and also mineralization (specular hematite) in both the dolomite and the quartz veins.

In the southeastern part of the quarry, there is a 5-meter (16 ft) level of slightly dolomitic quartzitic sandstone, in thick and massive beds (Pinnacle Formation ?). Finally, greenish dark grey mudshale or schist limits the quarry at the Southeast.

Translated from this original MRNF text :

Dolomie du Groupe de Oak Hill (Formation de White Brook), variant de gris très clair à gris bleuté, parfois brun pâle, violet, verdâtre ou rouge. Ces dolomies forment deux niveaux, horizons ou lentilles de quelques décimètres d'épaisseur, visiblement tectonisés (plissés ou boudinés). Ces niveaux sont séparés par des lambeaux de schiste à chlorite, de grès fin, laminé et de minces lits de conglomérats à particules de quartz de 2 à 4 mm.

Présence de veines de quartz d'une largeur variant de 0,2 à 40 cm.

Présence également de minéralisation (hématite spéculaire) se retrouvant dans la dolomie et dans les veines de quartz. Du côté sud-est de la carrière, on note la présence d'un niveau de 5 m constitué de grès quartzitique légèrement dolomitique, en bancs épais et massif (Formation de Pinnacle ?). Finalement, l'exploitation se limite vers le sud-est à un mudshale ou schiste, gris foncé verdâtre.
