所有矿床都位于单旋回带边缘(MBBZ)附近的单旋回异地岩体Laurier山地西边。该带的岩石为高级角闪岩相和麻粒岩相变质岩。Laurier山地以中元古代的大理岩、富铝的副片麻岩和石英岩为主。这些变质岩被与中到新元古代同构造至晚构造期的岩体侵入。MBBZ与从魁北克Basktong水库延伸到渥太华Bancroft地区的主剪切断裂带相连。对于Maniwaki-Grand- All deposits are located on the western side of the Laurier hills in the single-tremolo allograin near the single-swirling zone edge (MBBZ). The belt rocks are high amphibolite facies and granulite facies metamorphic rocks. The Laurier Mountains are dominated by Mesoproterozoic marble, aluminum-rich paragneiss and quartzite. These metamorphic rocks were intruded into the rock mass with the same tectonic-to-late Neoproterozoic tectonic period. The MBBZ is connected to the main shear fault that extends from the Basktong Reservoir in Quebec to the Bancroft area in Ottawa. For Maniwaki-Grand-
