A geochemical and petrological comparison of felsic igneous rocks from the Beaulieu River volanic belt, Northwest Territories (NTS 16/85I)

Abstract

Poster discussing research to test if the Amacher Granite served as the upper-crustal volcanic plumbing system responsible for the Neoarchean volcanism that produced felsic volcanics of the Beaulieu Group, rhyolites of the volcanic belt, the Amacher granite, and felsic dykes were investigated. Field relationships, petrography, and whole rock major oxide and trace element geochemistry of thirteen samples were compared.
