侵入岩

不同的地质环境为喷出岩或侵入岩。

A variety of geological environments are extrusive or intrusive rocks .

而侵入岩中的N2含量和氮同位素组成更多地反映了地壳中含氮物质浓度及同位素组成特征。

But for the intrusive rocks , the nitrogen content and isotope compositions better reflect the content and isotope compositions of nitrogen-bearing matter in the crust .
