WebSince most deposits are lithified, to quantify the grain size distributions (GSDs), image analysis was performed. The facies are distinct based on their GSDs and the fine ash to coarse+fine ash ratios. These provide insights into the fragmentation intensities and water–magma interaction efficiencies for each facies. Web6 aug. 2009 · Great Slave Lake is located in the Northwest Territories. It is the second largest lake entirely within Canadian borders, the fifth largest in North America, and the tenth largest in the world. With a maximum depth of 614 m, it is also North America’s deepest lake. Two arms, referred to as the North and East arms, extend from the lake.
