A·里特曼的《火成岩的稳定矿物组合——计算方法》一书,提出了一种岩石化学计算方法。虽然此法在国外从该书出版七年以来,反映不大,应用者很少,但是,在国内曾有人为之宣传,并有中文译本出版,也有一些地质人员正在应用。由于该书编写时不够仔细,有些错误之处,特在此写出,以供应用该书之方法者加以注意。其中有部分错误已经译者以脚注改正,这里不再重复。至于里特曼计算方法的优缺点,可能各个阅者见仁见智,互有不同,在此不加评论。本文所指出的问题,虽然是对原文而言,但文中所列页码系指中译本页码。 A. Ritterman’s book “Computational Methods for Stabilizing igneous Rocks - A Methodology” presents a rock chemistry calculation method. Although this law was published abroad for seven years from the book, it has not been reported much and has few applications. However, some people in China publicized it, published Chinese translations, and some geologists are applying it. Because of the book is not written carefully enough, some mistakes, especially here to write, for the method used to pay attention to the book. Some of these errors have been transliterated by footnotes and will not be repeated here. As for the advantages and disadvantages of the method of calculating Reitman, readers may have different opinions, different from each other, without comment here. The problem pointed out in this article, although the original text, but the page number listed in the text refers to the Chinese version of the page number.
