通过对庐山星子群变质基性火山岩岩石学， 地球化学及其形成的大地构造环境的综合研究发现， 星子群变质基性火山岩具有岛弧拉斑玄武岩和洋中脊玄武岩的双重特征， 是扩张弧后 （或弧间） 盆地环境的产物。对比研究表明， 星子群既不是来源于华夏古陆的 “飞来峰”， 也不同于扬子古陆东南缘的四堡群， 冷家溪群， 它是一块独立的前寒武纪基底。
Based on the comprehensive study on the petrology and geochemistry of the metamorphic base volcanic rocks in the Lushan Xingzi Group and its tectonic setting, it is found that the Xingzi Group metamorphic basement volcanics have the dual characteristics of island arc tholeiitic basalt and mid-oceanic basalts, (Or arc) basin product of the environment. Comparative studies have shown that the asteroid group is neither a “flying peak” originating from Huaxia ancient land nor the Si Baoqun and Lengjiaxi group in the southeastern margin of the Yangtze ancient continent. It is an independent Precambrian basement.
