查瓦里茨基的岩石化学计算方法,从1935年创始以来,已有半个世纪以上的历史。如今仍有不少地质人员,在岩石化学研究中使用它。并且,它是苏联和东欧国家中最重要的一种岩石化学计算方法。查氏法各种数值用于岩浆岩的图解中,以表明岩类的图区分布,主要有三种形式:1.查氏所制的“喷出岩主要种属化学成分投影图”:其底图为查氏展开立体图解,限于喷出岩,图上没有岩石分类界限,只有喷出岩的大略位置。2.查氏的岩石化学分类:据 Q 的大小分类,a/c 值的大小分科,再据6值分次科。3.《苏联地质测量方法指南》(比例尺1∶5万,1974)中的“侵入岩 a-b 值定名”。由于查瓦里茨基法具有一些优点,在我国,除有人采用它外,还在其基础上发展了一些
Chavalitki’s petrochemical calculation method, from its inception in 1935, has more than half a century of history. There are still many geologists who use it in petrochemistry. And it is the most important petrochemical calculation method in the Soviet Union and Eastern Europe. Various values of the Chakra method are used in the illustration of the magmatic rocks to show the distribution of the lithosphere pattern. There are mainly three forms: 1. The projection chart of the chemical composition of the main species of the expelled rock produced by Chadian: The picture shows a three-dimensional diagram of Charles’s expansion, limited to the jet rock, rock classification map is no limit, only the approximate location of the jet rock. 2. Cha’s petrochemical classification: According to the size of the Q classification, a / c value of the size of sub-Division, and then according to 6 sub-sub-Division. 3. “Intrusive rock a-b value designation” in the “Guidelines for the Geological Survey of the Soviet Union” (scale 1: 50000, 1974). As Chavariki method has some advantages, in our country, except some people use it, but also on the basis of some developed
