Because volcanic and plutonic rocks of the Abitibi greenstone belt show fairly uniform positive Nd values (at 2700 Ma), recent interpretations have assumed that the belt represents a... [Pg.161]

As already discussed, in the Abitibi greenstone belt of the Superior craton, extensive dating of volcanic units, their inherited zircons, and feeder dykes cutting imits lower in the stratigraphy has established coherent stratigraphy where previous workers had proposed a tectonic collage. [Pg.163]

Are the cyclic, bimodal, mafic to felsic sequences such as those of the Abitibi greenstone belt compatible with an oceanic plateau origin The zircon inheritance as well as the abimdance of felsic volcanic rocks seem incompatible with such an origin. Hence, where are the Ontong-Java plateaux of the past (cf. Kerr et al. 2000) ... [Pg.164]
