杨山萤石矿位于华北地台南缘,探明工业矿矿石量309.3万t,为河南省新近发现的又一大型萤石矿床.通过对杨山萤石矿成矿地质背景、矿床地质、矿石特征及围岩稀土元素地球化学特征分析研究,发现杨山萤石矿围岩轻稀土相对富集,稀土元素总含量较高,配分曲线为相对较缓的右倾斜,Eu弱亏损,Ce无亏损,属于东秦岭改造型花岗岩,认为杨山萤石矿应为断裂带充填交代型矿床.
Yangshan fluorite ore lies in the south edge of Huabei platform .It has proven reserves of 3.093 Mt .It is one of the large scale fluorite ores found in Henan province recently .According to the study of the geological set ,the deposit features ,mineral features and the REE geochemistry of host rock ,the results show that the total rare earth content is high ,the light rare earth is enriched ,the distribution pattern is leaning to the right gently ,the Ce is normal while Eu is negative anomaly(weak) .The host rock belongs to reformatory granite .Yangshan fluorite ore may be a deposit of fault filling replacement type .
