Continental extensional setting for the Archean Belingwe Greenstone Belt: comment and reply
Article Abstract:
M.A. Hunter et al employed stratigraphic data from the basal Manjeri Formation of the Archean Belingwe Greenstone Belt to prove the validity of the ensialic model for the whole structurally complex belt. Based on these data, they refuted previous studies that claimed that a several kilometers-thick pile of 2692 plus or minus 9 Ma basalts and komatiites in the upper region of the greenstone belt is allochthonous. While Hunter et al provided data that support field relationships in the Belingwe Greenstone Belt, these data do not explain the emplacement of the Mberengwa allochthon.

Global mafic magmatism st 2.5 Ga: remnants of an ancient large igneous province?: comments and reply
Article Abstract:
Two commentaries on the subject of global mafic magmatism at 2.5 Ga are presented. Among the contentions raised against the article of Larry M. Heaman are the validity of the claim that the Matachewan igneous events and coeval magmatism are the oldest evidences of a large igneous province and the basis of the reconstruction of the supercontinent. The response of Heaman to these contentions is presented.
