Primitive kimberlite magmas from Jericho, N.W.T., Canada: constraints on primary magma chemistry Price, Susannah Eloise

Abstract

In this thesis I present petrographic and geochemical data for six aphanitic kimberlite samples from the Jericho kimberlite pipe, N.W.T., Canada. Three samples derive from chilled margins where kimberlite dykes cooled against wall rock; three samples represent flow differentiated margins of a kimberlite diatreme. The chilled margin samples (JD51, JD69 and JD82) are texturally representative of a melt phase with relatively few microphenocrysts (
