摘要
在以往围岩蚀变的质量迁移研究基础上，本文提出了一种判定惰性元素的方法，同时结合等浓度线和加权最小二乘法，给出研究热液围岩蚀变中组分质量迁移的计算方法。在判定惰性元素时，更多地应用了线性回归分析中的方差分析与回归诊断参数与计算方法。这一系列的参数与方法被用于评述沃溪金锑钨矿床褪色化围岩蚀变质量迁移，取得了较好的效果。研究表明，在沃溪矿床围岩蚀变过程中，Ｔｉ表出现了一定的活动性。
The present paper advances a new method to determine immobile elements for the mass transport calculation during the wall rock alteration of ore forming processes. Here, the analysis of variance and the influence analysis are used to establish a linear regression model for the research of wall rock alteration. As a study case, the method is applied to discuss the mass transport of the major elements in the bleached alteration in the Au Sb W deposit at Woxi, Hunan Province, China. The calculation gives well consistent result with both the geological observations and geochemical studies. The study suggests that the element Ti shows some mobility under given conditions of the wall rock alteration in the Woxi deposit so it would not be suitable to take Ti as an immobile element arbitrarily for evaluatior of mass transport in a wall rock alteration process.
