This book was released on 2000 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents results of 1999 field studies focusing on the structure & stratigraphy within the Wallace Lake greenstone belt of east central Manitoba. The stratigraphic results involve redefinition of some of the sequences previously described in the belt and the introduction of new stratigraphic nomenclature. The nature of the contact between stratigraphic assemblages, and the internal stratigraphy of these assemblages, is then presented. This is followed by a discussion of the stratigraphic position of various komatiitic units found in the belt. The final sections describe the geochemistry of the volcanic rocks and the structural history of the greenstone belt.
