氮同位素地球化学在固体地球科学研究很少被关注，主要是由于在地壳岩石中氮丰度很低（<1000ppm）和氮难于从硅酸盐中提取出来。

Nitrogen isotope geochemistry in minerals and rocks has not been fully studied , primarily because of very lower ( < 1000 ppm ) concentration of nitrogen in the crustal rocks and the difficulty to extract nitrogen from silicate minerals and rocks .

对于大多数金属成矿元素，地壳特别是上地壳是大多数矿石和矿胎的储库，地壳丰度是元素富集成矿的物质基础。

For most ore metals , the continental crust , especially , the upper continental crust , is the repository of all ores and protores . Therefore , the average crust abundance of metals is the material base for the enrichment of ore metals .
