摘要
高纯石英广泛应用于半导体、光伏、光通讯、电光源等高新技术产业,在国家战略性新兴产业、经济安全和国防安全等方面都具有重要地位和作用,是世界稀缺、我国短缺的资源。脉石英是加工高纯石英砂的理想原料之一,本文在广泛收集和研究脉石英勘查成果的基础上,根据脉石英矿床的大地构造环境、分布特征、成矿特征和控矿因素,划分了中国脉石英矿床的成矿区带,并对各个成矿区带的成矿特征做了简述;总结了中国脉石英矿床成矿规律。脉石英矿床类型主要以岩浆成因热液型为主,其次为变质成因热液型和伟晶岩型,主要成矿期为燕山期,其次为华力西期、加里东期、晋宁期和印支期。初步划分了脉石英成矿区带27个,提出吕梁、南秦岭、桐柏-大别、东海-赣榆、阿尔泰地块共5个脉石英成矿区带是我国重要的高纯石英用脉石英成矿区带。本次脉石英成矿规律总结及成矿区带的划分对脉石英找矿勘查部署提供了理论依据。
High-purity quartz is widely used in high-tech industries such as semiconductors,photovoltaics,optical communication,and light sources.It plays an important role in national strategic emerging industries,economic security,and national defense security,and is a scarce resource in the world and China.Vein quartz is one of the ideal raw materials for processing high-purity quartz raw materials.Based on extensive collection and research of vein quartz exploration results,this article divides the mineralization zones of vein quartz deposits in China according to their tectonic environment,distribution characteristics,mineralization characteristics,and controlling factors,and briefly describes the mineralization characteristics of each mineralization zone;Summarized the ore-forming laws of vein quartz deposits in China.The main types of vein quartz deposits are magmatic hydrothermal vein type,followed by metamorphic hydrothermal vein type,and pegmatite vein type.The main mineralization periods are Yanshanian,followed by the Hualixi,Caledonian,Jinning,and Indosinian periods.27 vein quartz mineralization zones have been preliminarily divided,and it is proposed that 5 vein quartz mineralization zones,including the Lüliang,South Qinling,Tongbai-Dabie,East China Sea-Ganyu,and Altai blocks,are important high-purity quartz vein quartz mineralization zones in China.The summary of the mineralization rules of vein quartz and the division of mineralization zones provides a theoretical basis for the exploration and deployment of vein quartz.
