本文据曾工作过或收集到的华南地区两类(同熔型与改造型)花岗岩十三个岩体(群)176个化学分析样,着重讨论了以化学成分ANKC值、A1′值等划分两类不同成因花岗岩的可能性,并以统计方法提供了较优的划分方案,认为由主分量分析引伸的直观图能判别,是划分华南地区两类不同成因花岗岩比较有效的手段。
Based on 176 chemical analysis samples of thirteen rock mass (group) of two types of (same type and modification) granite in South China that have been collected or collected in this paper, the chemical composition ANKC value and A1 ’value are mainly discussed Two types of granites with different genetic origins, and provides a better classification scheme by means of statistical methods. It is considered that the intuitionistic analysis of principal component analysis can distinguish the two types of granites from two different genesis in South China.
