摘要
通过实验研究,利用国际标样标定,系统分析了松潘-阿坝地区三叠系的岩石矿物相、伊利石结晶度、粘土矿物类型含量及组合、混层矿物混层比、镜质体反射率等评论指标,研究了该区的成岩演化特征,并对成岩变质阶段进行了划分,为该区的成岩演化研究和油气成藏条件研究提供了评价依据。
In this paper,diagenetic features have been studied and diagenetic stages identified for Triassic in the Songpan-Aba area by experimental analysis on diagenetic indicators,such as petrologic analysis on mineral facies,investigations of clay minerals and assemblage features,illite crystallinity determination colibrated to standardized scale （CIS）,percent of smectite layer in mixed clay minerals,vitrinite reflectance determination,and thus help the diagenetic study of sedimentary rocds and pool forming conditions.
