烟台市蓬莱区雨山萤石矿地质特征及成因分析

Geological Characteristics and Genesis Analysis of Yushan FluoriteDeposit in Penglai District, Yantai City

作为重要的非金属矿产资源,萤石主要用于制备氢氟酸,也广泛用于生产建筑材料。本文结合烟台市蓬莱区雨山萤石矿的成矿地质背景,分析矿体特征、矿石类型与矿石质量,明确成矿规律与找矿方向。矿床主要发育在研究区伟德山序列侵入岩范围内,断裂构造直接控制矿床的分布,物质主要来源于低温热液作用。研究表明,根据矿床成因,该萤石矿为低温热液充填脉型萤石矿床,研究区萤石矿脉成矿条件较好。

As an important non-metallic mineral resource,fluorite is mainly used to prepare hydrofluoric acid and is also widely used in the production of building materials.Based on the geological background of the Yushan fluorite deposit in Penglai district,Yantai city,this paper analyzes the characteristics of the ore body,ore types,and ore quality,and clarifies the ore-forming laws and prospecting directions.The deposit is mainly developed within the range of intrusive rocks in the Weideshan sequence of the research area,and the distribution of the deposit is directly controlled by fault structures,and the material mainly comes from low-temperature hydrothermal processes.Research has shown that based on the genesis of the deposit,the fluorite deposit is a low-temperature hydrothermal filled vein type fluorite deposit,and the fluorite vein mineralization conditions in the study area are relatively good.
