| 摘 要： | 根据佛坪地区广泛出露的一套副变质岩系的岩石组合、矿物组合、变质相特征和岩石地球化学特征的分析，认为它们是一套中深变质的碎屑岩－泥质岩－碳酸盐岩建造。原岩形成于相对稳定的大陆边缘－微板块内的陆表海环境。经过角闪岩相区域变质作用，形成了佛坪地区较为完整的孔兹岩系

| Abstract: | Based on the analysis on the rock assemblages,mineral assemblages,metamorphic facies and lithogochemistry of the parametamorphite series,occured widely in Foping area,it is thought that this rock series could belong to mesometamor phic rock series,with clastic rock argillaceous carbonate.The source rock could be formed in the condition of relatively stable continental margin epicontinental marine in micro plate.The bedded metamorphite series in Foping area had been formed by regional metamorphism of amphibolite facies. |
