摘　　要：河南省鲁山县大尖垛萤石矿床位于华北地台南缘崤山—鲁山拱断束和栾川—薄山陷褶断束的接合部位。通过对成矿特征及控矿因素的研究,确认了矿床成因类型属中低温热液型,矿体主要受岩浆活动及断裂作用双重控制,在该区侵入断裂破碎带中的萤石-石英脉及各类萤石矿化是找矿的唯一标志,断裂破碎带沿走向和倾向分支复合部位是成矿的最有利部位。本研究为今后寻找该类矿床具有一定的指导意义。The Dajianduo fluorite deposit in Lushan County,Henan Province is located at the junction of Xiaoshan-Lushan arch fault bundle and Luanchuan-Boshan fold fault bundle on the southern margin of North China platform.Through the study of metallogenic characteristics and ore-controlling factors,it is confirmed that the genetic type of the deposit belongs to the medium-low temperature hydrothermal type,and the ore body is mainly controlled by magmatic activity and fracture.The fluorite-quartz vein and all kinds of fluorite mineralization in the intrusive fault fracture zone in this area are the only signs of prospecting.The composite part of the fault fracture zone along the strike and dip branches is the most favorable part of mineralization.This study has certain guiding significance for the future search for such deposits.
