The Keweenawan rocks of the Lake Superior region afford an                      excellent opportunity to study contemporaneous volcanic and                     plutonic activity associated with continental rifting in the                    Proterozoic.  By comparing genetically related volcanic sequences               and plutons on a regional basis, a range of basic problems can be               addressed.  In a pilot study the PI has discovered very primitive               basaltic and picritic lavas near the base o the Mamainse Point                  Formation (MPF) in Ontario.  These lavas display spectacular                    quench-olivine textures and systematic chemical variations with                 stratigraphy.  This project will sample the remaining four-fifths               of the MPF and analyze for major and trace elements by XRF and DC               plasma spectrometry.  Mineral chemistry will be determined by                   electron microprobe, and geochemical modeling will be attempted                 in order to delineate the processes responsible for the origin                  and compositional evolution of this important volcanic sequence.                Results will be used to evaluate the hypotheses derived from                    previous work, and to determine the relationship between the                    plutonic and volcanic rocks.  An attempt will be made to                        characterize the nature of the subcontinental mantle source and                 to evaluate possible relationships between these lavas and                      plutonic anorthosite complexes.
