摘要：

The possibility of para-amphibolites originating from the metamorphic transformation of graywackes is investigated. A series of 35 samples of Vosges graywackes has been studied and the geochemical trends for major and trace elements have been determined to this end. The strong similarity of the geochemical characteristics of this group of graywackes to those of a series of para-amphibolites of the Western Alps conforms to the present hypothesis. By comparing sedimentary geochemical trends with igneous trends one is able to distinguish ortho- from para-derivatives. © 1969 Springer-Verlag.
