吉林省橄榄石宝石矿床分布特征、勘查开发现状及发展远景

本文在野外地质勘查及系统分析前人工作资料的基础上,对吉林省橄榄石宝石矿床区域分布及勘查开发现状进行归纳总结。吉林省橄榄石宝石矿主要分布在吉林省东部,已发现的橄榄石宝石矿床均赋存于新生界新近系上新统船底山组玄武岩中。严格受敦化-密山岩石圈断裂及其次级断裂控制。在找矿方向上应扩大已有矿区勘查范围,加大勘查力度及对省内船底山组玄武岩分布地区做重点勘查工作部署,力求在橄榄石宝石矿找矿方面取得更大的突破。同时对橄榄石宝石矿业发展远景进行探讨。

Distribution characteristics,exploration and development statusand development prospect of olivine gem deposits in Jilin Province

Based on the field geological exploration and systematic analysis of previous work data,the author summarizes the regional distribution and exploration and development status of olivine gem deposits in Jilin Province.The olivine gem deposits in Jilin Province are mainly distributed in Eastern Jilin Province,and the discovered olivine gem deposits are all hosted in the basalt of Chuandishan Formation of Neogene and Pliocene of Cenozoic.It is strictly controlled by the Dunhua-Mishan lithosphere fault and its secondary faults.In the direction of prospecting,we should expand the exploration scope of the existing mining areas,intensify the exploration efforts and make the key exploration plans for the basalt distribution area of Chuandishan Formation in the province,so as to make a greater breakthrough in the exploration of olivine gem.At the same time,the development prospect of olivine gem mining industry.
