CIPW标准矿物计算方法与程序设计

Calculation Method and VBA Program of CIPW Norm Minerals

CIPW标准矿物计算方法是一百多年前由Cross、Iddings、Pirrson和Washington四位学者设计的岩浆岩岩石化学数据的处理方法,至今在岩浆岩研究中仍发挥着重要的作用。国外学者先后开发了多款软件及Excel工作表,但国内在相关的软件开发方面却显得薄弱。本文在全面评估CIPW标准矿物计算方法的基础上,介绍了作者应用Excel VBA设计的一套计算机程序,该程序除了可计算出标准矿物组成以外,还可计算常用的岩石化学参数。经与前人的计算结果对比表明,该程序的计算结果正确的、可靠的。

CIPW norm mineral calculation is a petrochemical data processing method for magmatic rocks de-signed by Cross,Iddings,Pirrson and Washington more than 100 years ago,which still plays an important role in the study of magmatic rocks.Foreign scholars have developed a number of software and excel worksheet,but domestic software development is still weak.Based on the comprehensive introduction of the calculation method of CIPW norm minerals,the authors have designed a computer program with Excel VBA.In addition to calculating the norm mineral composition,the program also calculates the commonly used petrochemical parameters.By compared with the results of predecessors,the calculation results by the program are proved to be correct and reliable.
