斑岩

Differently, among the Cenozoic alkaline-enriched porphyries in Jianchuan, Beiya et al., Pb isotope composition is dominated by Yangtze block and Gondwana continent together,〓Pb/〓Pb ratios increase, and most of them approach 18.5, average 18.556, which is apparently of the characteristics of hybrid composition of Yangtze Pb isotope province and Gondwana Pb isotope province.

与此不同的是，剑川、北衙一带的新生代富碱斑岩中，Pb同位素组成明显地表现为扬子地台与冈瓦纳大陆共同作用，〓Pb/〓Pb比值增加，多数接近18.5，平均值为18.556，明显具有扬子Pb同位素省与冈瓦纳Pb同位素省混染杂交的特征。
