Evolution of Laramide Igneous Rocks Related to Mineralization in Southern Arizona: A Trace-Element and Nd-Sr Isotope Study

该项目旨在建立 Laramide岩浆活动与成矿作用之间的关系 亚利桑那州东南部和西北部， 下伏地壳基底岩石的性质和年龄。 在 此外，矿化和非矿化的地球化学特征 矿化火成岩体进行对比。 这些数据将帮助 确定为什么矿化会发生在它发生的地方。 结果 将被证明是有用的概念化矿产勘探 模型以及底层地壳在多大程度上充当了 金属的最终来源。

This project is aimed at establishing the relationship between Laramide magmatic activity and mineralization in southeastern and northwestern Arizona where there are differences in the nature and age of underlying crustal basement rocks. In addition, geochemical characteristics of mineralized and non- mineralized igneous bodies will be compared. These data will help determine why mineralization occurs where it does. The results will prove useful to conceptualization of mineral exploration models and to what extent the underlying crust serves as the ultimate source of metals.
