Abstract

Abstract In this communication we present a brief response to Hawthorne (2023) who, in a paper in volume 87, doi.org/10.1180/mgm.2023.8 (this journal), claims evidence for violations of the electroneutrality principle in mineral formulae derived through IMA–CNMNC procedures: i.e. the dominant-constituent rule, the valency-imposed double site-occupancy, the dominant-valency rule, and the site-total-charge approach (STC). His statement is not correct as the STC method is based on the end-member definition; thus, it cannot violate the requirements of an end-member, particularly the laws of conservation of electric charge. The STC was developed to address the shortcomings in the previous IMA–CNMNC procedures. The real question is: which method to use to define an end-member formula? Currently, there are two approaches: (1) STC, which first identifies the dominant end-member charge arrangement and then leads to the dominant end-member composition; (2) the dominant end-member approach.
对Hawthorne(2023)的简短评论:“关于独特矿物的定义:对当前IMA-CNMNC程序的批评”
在本通讯中,我们对Hawthorne(2023)进行了简要的回应,他在第87册doi.org/10.1180/mgm.2023.8(本期刊)的一篇论文中声称,有证据表明通过IMA-CNMNC程序推导出的矿物配方违反了电子中性原则:即优势成分规则、价施加的双位点占用、优势价规则和位点总电荷方法(STC)。他的说法是不正确的,因为STC方法是基于端元定义的;因此,它不能违反端元的要求,特别是电荷守恒定律。STC是为了解决以前的IMA-CNMNC程序中的缺点而开发的。真正的问题是:用什么方法来定义端元公式?目前,有两种方法:(1)STC,首先确定优势端元电荷排列,然后得出优势端元组成;(2)优势端元方法。
