摘要

Cordierite-bearing lavas (CBL; ~ 105 ka) erupted from the Mt. S. Angelo volcano at Lipari (Aeolian arc, Italy) are high-K andesites, displaying a range in the geochemical and isotopic compositions that reflect heterogeneity in the source and/or processes. CBL consist of megacrysts of Ca-plagioclase and clinopyroxene, euhedral crystals of cordierite and garnet, microphenocrysts of orthopyroxene and plagioclase, set in a heterogeneous rhyodacitic-rhyolitic groundmass containing abundant metamorphic and gabbroic xenoliths. New petrographic, chemical and isotopic data indicate formation of CBL by mixing of basaltic-andesitic magmas and high-K peralu-minous rhyolitic magmas of anatectic origin and characterize partial melting processes in the lower continental crust of Lipari. Crustal anatectic melts generated through two main dehydration-melting peritectic reactions of metasedimentary rocks: (1) Biotile -f- Aluminosilicate + Quartz + Albite = Garnet + Cordierite + K-feldspar + Me (2) Biotite + Garnet + Quartz = Orthopyroxene + Cordierite + K-feldspar + Melt. Their position into the petrogenetic grid suggests that heating and consequent melting of metasedimentary rocks occurred at temperatures of 725

Angelo火山是高钾安山岩，在地球化学和同位素组成方面显示出一定范围，可反映出源和/或过程的非均质性。 CBL由Ca-斜长石和斜生辉石的大晶体，堇青石和石榴石的自体晶体组成，邻苯二酚和斜长石的微细晶石组成，位于含有丰富的变质和辉长岩异种岩的非均质的流纹岩-流纹岩地层中。新的岩石学，化学和同位素数据表明，玄武质安山岩和安第斯高钾钾流纹岩浆岩混合形成了CBL，并表征了利帕里下部陆壳的部分熔融过程。沉积物岩石的两个主要的脱水熔融包晶反应产生了地壳的阳极熔体：（1）生物质-f-铝硅酸盐+石英+阿尔比特=石榴石+堇青石+钾长石+熔体; （2）黑云母+石榴石+石英=邻辉石+堇青石+钾长石+熔体。它们在成岩网格中的位置表明，变质沉积岩的加热和随后的融化发生在725
