| 摘 要： | 应用回归分析方法对吉林省东部新生代碱性玄武岩中的K_2O含量与岩浆来源深度、火山岩年龄进行的相关性分析表明,K_2O含量与岩浆来源深度之间存在着较好的幂函数相关关系,而K_2O含量与火山岩年龄之间存在着较好的指数函数相关关系。利用得出的回归方程对东北地区某些新生代火山岩的岩浆来源深度进行了预测,并对回归方程所代表的地质意义进行了讨论。

| Abstract: | Using regression analysis method, we analysed the relationship between K2O content to magma genetic depth and volcanic diagcnctic age for Cenozoic alkali basalts in East Jilin Province. The results showed that there was a power function relationship between K2O content and magma genesis depth and an index function relationship between K2O content and volcanic diagenctic age for Cenozok alkali basalts. With the regression equation obtained, we calculated the depths of magma genesis for some Cenozoic volcanic rocks in Northeast China. Also, we discussed the geological significance reflected by the regression equations. |
