Excerpt from The Monteregian Hills, a Canadian Petrographical ProvinceThe greater part of Mount Royal is composed of an essexite, usually very basic, the dark-colored constituents forming a very large proportion of the whole rock. This was classed by Hunt as a dolerite. But is almost identical with the essexite of Mount Johnson. Which Hunt classes as a diorite. This same rock is stated by Hunt to make up the greater part of Montarville and Rougemont and to form a portion of Yamaska mountain. An examination of thin sections of specimens of the Rougemont rock in the petrographical collection at mcgill University shows it to be an essexite, rich in olivine. Dresser has found it to con stitute approximately one-half of Shefford mountain and also to form large areas in Brome mountain. It makes up the greater part of Mount Johnson and forms the mass of Beloeil.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
