2.Two Mountains and Montmorenci System. " The dislocations giving rise to this system took place," in Marcou's opinion, " at the end of the deposit of cheap michael kors 2013 outlet the first group of Lower Silurian cheap mk purses outlet that is, after the formation of the Potsdam group. tiffany cufflinks Its direction appears to be approximative E. 40 N. and W. 40 S. The beds of the Potsdam group are greatly tiffany co outlet elevated near the junction with the Metamorphic rocks, and are often metamorphosed themselves, which gives them a very hard quartzite aspect.

"4.Notre Dame Mountain System. This system Marcou tiffany sets holds to date " from the end of the deposition of the Lower Silurian." The " numerous strata of michael kors outlet online black Schist, distinguished in the State tiffany engagement rings of New York by the name of tiffany earrings Utica and Hudson River group," " which form almost entirely the banks of the liiver Richelieu, of the St. Lawrence lower than tiffany necklaces Montreal, and on which is situated the City of Quebec, have been michael kors outlet upheaved along the whole of this line, to Cape Roziere at the extremity of Gasp6. The Notre Dame Mountains, formed of eruptive and metamorphic rocks, some of tiffany jewelry outlet whose summits attain 3,500 feet, owe their origin entirely to this movement, whose general direction appears to be E.
