| 以回归分析方法确定围岩蚀变中的惰性元素主要有4个步骤,首先选取元素的测试数据并根据数据引入所估计的回归方程,第二步检验所选测试元素是否适用该回归方程,接着检验回归方程的显著性,以此检验所选的测试数据是否具有代表性,若上面3步均达到要求,即可进行残差分析,最终推断惰性元素,文章以八卦庙金矿床的铁白云质粉砂质千枚岩为例,选取SiO2、TiO2等13种化合物以回归分析方法尝试找出矿区围岩蚀变中的惰性元素,计算结果表明,TiO2和Al2O3并非八卦庙矿区的“惰性组分”,则该矿区的惰性元素则可往Zr方向靠拢。 |
| 英文摘要: |
| For determining the inert elements during wall-rock alteration with regression analysis method, there are four steps:1) to choose the analytical result of and to input those data into regression equation; 2) to test the chosen element suitable for the equation or not; 3) to test the significance of the regression equation so as to test the chosen data are typical or not; 4) if meet the requirements by above three steps, to do residual analysis so as to find the inert element. In this paper, taking the ferruginous dolomitic silty phyllite in Baguamiao gold deposits as an example, we tried to find the inert element in wall-rock alteration using regression analysis method for the thirteen components including SiO2 and TiO2 and concluded that Zr rather than TiO2 and Al2O3 is the inert components. |
