[30] There was also violent volcanic activity, including the eruption that produced the Millburg/Big Bentonite ash bed. [57] More than 100million years later, in the Permian, an overall warming trend occurred. This produced the continent of Laurussia. When the ice sheets finally melted (between 10 000-18 000 years ago) many of these valleys were partly filled by sands, gravels and other outwash material carried by the meltwaters. It is beautiful during all 4 seasons. During the Early Proterozoic they were covered by sediments, most of which has now been eroded away. [16], Over the next 900 million years, Laurentia grew by the accretion of island arcs and other juvenile crust and occasional fragments of older crust (such as the Mojave block). They actually belong to a much older formation known to some as the Canadian Shield, as the Laurentian Shield to others, and as the Precambrian Shield to the rest. There had also been expansion from Lachute and Grenville up the Rouge River valley towards Arundel with the settlements around Harrington.

[56] Due to sea level fluctuation, these intervals led to mudstone deposits on Laurentia that act as a record of events. [30], The great continental mass of Pangaea strongly affected climate patterns. Deformation of the Ancestral Rocky Mountains slowed in Permian time, reducing basinal accommodation and allowing marginal clastic sources to overwhelm the system. With a population of over 1.7 million people, Montreal is easily the largest metropolitan area in the greater Laurentian Mountains region.

[49], Pangaea reached its height about 250 Mya, at the start of the Triassic[50], The breakup of Pangaea began in the Triassic, with rifting along what is now the east coast of the US that produced red beds, arkosic sandstone, and lake shale deposits. Glaciers carve distinctive, steep-walled and flat-bottomed valleys. They average between 300m and 520m (984 ft.-1,706 ft.) in height, with the highest being Mont-Tremblant, at 875m (2,871 ft.). The ice also overdeepened the valleys that lead southward from the Shield, the most dramatic of which is the fjord of the Saguenay River (500 m cliffs and 600 m depths). Platinum group elements, also known as PGEs, are a group of elements that have specific properties which make them useful for various applications in industry. They are called the Laurentian.
