六种矿物电子探针分析值Fe^（3＋）和Fe^（2＋）换算的FORTRAN程序

A FORTRAN Program for Calculation of the Fe￣(3+)and Fe￣(2+)Contents in Six Kinds of Minerals from Electron-probe Analysis Data

矿物电子探针分析值Ｆｅ３＋和Ｆｅ２＋的换算是地质研究工作的重要内容，倘若手算，耗时费力，且易出错。本文针对辉石、黑云母、磁铁矿、钛铁矿、石榴石和绿泥石等六种常见矿物，设计并运行通过了电子探针分析值Ｆｅ３＋、Ｆｅ２＋换算的ＦＯＲＴＲＡＮ语言程序。程序具有电价差值法和剩余氧法二种计算调整方法，可供选择使用。

The calculation of the Fe3+ and Fe2+ contents in minerals from electron - probe analysis data is a common job in geologic studies. Manual calculation takes more time and effort,and makes, some drrors. This paper provides a FORTRAN Language program that converts total iror into Fe2O3 and FeO for pyroxenes, biotites, magnetites, ilmenites, garnets and chlorites,including the charge difference method and the surplus - oxygen method. The operator- computer conversation makes the operatin convenient and the calculating results can be writer in preparing file or be output by printers or screen.
