Archean Variolitic Lavas from Munro Township, Ontario

Abstract

<p> Chemical variations between the matrix and variole fractions of variolitic lavas are quite distinct. Analyses for major. and trace elements and trace gold content was carried out on separated fractions of matrix and varioles from several handspecimens. </p> <p> Discussion of the results (including the origin of variolitic textures) was aided by thin section analysis and field relationships. </p>
