| 摘 要： | 本文通过对四川北部秦巴地区的漳腊、松潘、平武三图幅1:20万水系沉积物区域化探扫面稀土元素Y、Ce、La的大量资料研究后认为,它们在进行金、钨等异常分类,区分不同类型的岩浆岩的矿化异常,研究不同构造区的地层与成矿特征以及区域的元素地球化学特征等方面有着独特的作用,确实“是一个良好的地球化学指示剂”。为研究区域化探扫面资料提出了新思路。

| Abstract: | According to an investigation into abundant data of rare earth elements V, Ce, La obtained during the 1:200, 000 regional stream sediment survey for Zhangla, Songpan and Plngwu sheet areas, this paper holds that these ele ments can play a peculiar role in classification of Au, W and some other ano malies, differentiation of mineralization anomalies of various magmatic rocks, and the study on strata and metallogenic characteristics of different tectonic areas as well as on regional geochemical characteiistics of elements, thus un doubtedly serving as good geochemical indicators. This understanding opens ip a new train of thought for the study of regional geochemical data. |
