Mont Yamaska is composed of igneous rock and hornfels. The igneous rock is mostly mafic with much gabbro, essexite, and a titanium-rich pyroxenite. Mont Yamaska might be the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.[1] The mountain was created when the North American Plate moved westward over the New England hotspot,[1] along with the other mountains of the Monteregian Hills that form part of the Great Meteor hotspot track.
