摘　　要：出露于庐山地区的星子变质杂岩是扬子大陆的结晶基底，由变粒岩、各类云母片岩、石英片岩和斜长角闪岩组成。其主要岩类岩石化学和地球化学特征，说明它可能形成干活动大陆边缘，形成的时代为早元古代。Xingzi metamorphic complex exposed in Lushan area is the crys ta-llized basement of Yangzi continent,composed of leptynite, variouskinds of mica schist, quartz-schist and amphibolite,According to the features of petrochemistry and geochemistry of its major petrography,it indicates that it may be formed at the activity continental margin,the age of its formation is Early Proterozoic Era.
