Abstract

In order to study the ore-forming material source and ore-forming age of the Liuying fluorite deposit, the authors tested and analyzed the REE of 11 samples of rocks and ores, and determined the mineralization age of fluorite by Sm-Nd method. The results show that the chondrite-normalized REE patterns of wall rocks (marble+mica quartz schist), fluorite ore and Niuxinshan biotite monzogranite all have a rightly-dipping trend, but the distribution curves and statistical values of different parameters of fluorite ore and biotite monzogranite are closer to each other, indicating that they have obvious genetic relationship.The metallogenic age of fluorite is 141 Ma and the values of εNd(t) are negative, which shows that the main metallogenic epoch is early Cretaceous and the crust source characteristics are obvious. The metallogenic age of fluorite ore is basically consistent with that of SHRIMP zircon U-Pb age of Niuxinshan biotite monzogranite (132.4~138.4 Ma), suggesting that there is a close relationship between them, and the material sources should be consistent or similar.

Key words： rare earth element metallogenic age fluorite Liuying in Henan
