Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Precambrian Shield of Northern Saskatchewan has a complex metamorphic history with as many as six distinct thermotectonic events affecting various regions. Several of these result from major periods of crustal thickening attributed to orgenies, whereas others represent seperate pulses of unknown origin. As might be expected, it is the most recent of these that are the most extensively preserves and that can be documented most reliably. </SPAN></P><P><SPAN STYLE="font-style:italic;">Continued in:</SPAN></P><P><SPAN>GSC Open File 5443 Metamorphic map of Northern Saskatchewan, scale 1:1 000 000</SPAN></P></DIV></DIV></DIV>
