南岭成矿带中亚带发现花岗伟晶岩型铍矿

Discovery of granitic pegmatite type beryllium ore deposit in middle of Nanling metallogenic belt

铍矿是中国重要的战略性新兴产业矿产资源,其中以花岗伟晶岩型最为重要。南岭是中国重要的稀有金属、钨、锡多金属成矿带,以往发现的铍矿主要以矽卡岩型、云英岩型为主,花岗伟晶岩型铍矿较少。通过详细的野外和室内岩矿鉴定工作,笔者在南岭成矿带中亚带花岗伟晶岩中发现了粗晶状绿柱石,并确定其具有一定的规模,弥补了南岭地区铍矿类型单一的问题,为调查研究华南铍矿提供了新的线索。

Beryllium is an important strategic emerging industry mineral resource in China,and granite pegmatite is the most important type of beryllium deposit.Nanling is an important metallogenic belt of rare metals,tungsten and tin,where the beryllium deposits discovered are mainly of skarn type and greisen type,but granite pegmatite type deposits have been rarely found.Based on field work as well as indoor rock and mineral identification,the authors found the coarse crystalline beryl in the granitic pegmatite of the YYL deposit,which is located in the middle of the Nanling metallogenic belt.This study makes up for the single type of beryllium ore deposits in Nanling area,and provides a new clue for the investigation of beryllium deposits in South China.
