| 摘 要： | It is generally held that melanogranulites are of prograde metamorphic origin from basalts based on their layered structure and basaltic composition.Information about rock association,texture and structure,mineral assemblage and geothermometry indicates that melanogranulites in the area studied were derived from igneous norite-gabbro rather than volcanics.
