摘要
辽宁省稀土矿产调查历史久远,优势矿种主要为镧、铈、钇、镱等。已勘查发现中型稀土矿床2处、小型稀土矿床3处和矿化点11处,矿床(矿化点)成因类型主要有岩浆型、伟晶岩型、火山沉积变质型和冲积砂型。原生矿主要分布于本溪桓仁、丹东宽甸、凤城和营口等地,砂矿主要分布于丹东凤城、阜新、锦州和法库等地。通过对辽宁省稀土矿成矿地质背景、典型矿床成矿地质特征及主要成矿远景区成矿潜力评价的综合研究,总结出辽宁省稀土矿的成矿规律及重点找矿方向。
The investigation of rare earth mineral resources in Liaoning province has a long history.The dominant miner⁃als are rich in lanthanum,cerium,yttrium and ytterbium.According to geological statistics,2 medium⁃scale deposits,3 small⁃scale deposits,and 11 mineralization points have been discovered through explorations.The genetic types of REE depos⁃its(mineralization points)mainly include magmatic type,pegmatite type,volcanic sedimentary metamorphic type and alluvial sand type.Primary deposits are mainly distributed in Benxi Huanren,Dandong Kuandian,Fengcheng and Yingkou;and plac⁃er deposits are mainly distributed in Dandong Fengcheng,Fuxin,Jinzhou and Faku.Based on the comprehensive research on the metallogenic geological background of rare earth deposits in Liaoning province,the metallogenic geological characteristics of typical deposits and the metallogenic potential evaluation of the main metallogenic prospects,this paper summarizes the met⁃allogenic rules and key prospecting directions of rare earth deposits in Liaoning province.
