| 摘 要： | 对于中酸性火成岩,CIPW标准矿物与岩石实际矿物成分之间的差别是明显的。为了缩小这一差別,作者讨论了和岩石化学计算有关的若干问题,在此基研上提出了适用于中酸性火成岩的岩石化学计算方案。计算实例表明,本文方案能够弥补CIPW标准矿物分子法的某些不足。

| Abstract: | For acid-intermediate igneous rocks the discrepancy between CI..P.W. normative mineral and practical mineral composition is apparent. In order to reduce this discrepancy some problems concerning petrochemical calculations are discussed in this paper, and a new calculation program for acid-intermediate igneous rocks is proposed based on the resolution of these problems.Mineral composition of various acid-intermediate igneous rocks and some metamorphic rocks is calculated by the above-mentioned methods. It is shown that calculations of mineral composition by using the new program are approaching to the practical mineral composition, thus the program can serve as an additional approach to the C.I.P.W. method in some aspects. |
