| 摘 要： | 作为战略性关键金属矿产,锂矿勘查与研究已成为当今矿产勘查和地学研究的热点。项目组2017年以来通过多次野外勘查、系统取样与室内化验分析,确认在新疆和田县白龙山锂多金属矿床东部的雪凤岭一带发现了雪凤岭、雪盆和双牙3处花岗伟晶岩型锂多金属矿床。雪凤岭锂矿床由3个含矿伟晶岩脉群共计47条锂多金属矿体组成,矿体长32~360 m,厚0.9~8 m,走向110°~120°,倾角49°~78°。对雪凤岭矿区伟晶岩脉群研究,发现含矿伟晶岩脉群?含白云母伟晶岩脉群?块体石英长石伟晶岩脉群?含黑色电气石伟晶岩脉群?块体石英长石伟晶岩脉群?含白云母伟晶岩脉群?含矿伟晶岩脉群具对称分带特征,进而在距雪凤岭1550 m南部的双牙山和雪盆沟发现较好的锂矿体,其中双牙锂矿床主矿体长850 m,厚12 m,出露最宽处近100 m;雪盆锂矿床3条锂矿体,长800~1200 m,厚4~8 m,向西合成一个矿体,厚12~20 m。各矿体Li2O品位0.6%~4.02%。伴生BeO品位0.04%~0.15%,Rb2O品位0.10%~0.23%,Nb2O5品位0.007%~0.047%,Ta2O5品位0.003%~0.046%。预测雪凤岭、雪盆、双牙3个矿床334资源量共计Li2O为7.1886×105 t,BeO为2.648×103 t,Rb2O为1.433×103 t,Nb2O5为3.387×103 t,Ta2O5为1.727×103 t,雪凤岭一带有望成为一个超大型锂多金属稀有金属矿产基地。

| Abstract: | As a strategic metal,lithium has become a hot spot of today’s mineral exploration and geoscience research.On the basis of field survey and laboratory analyses since 2017,the authors discovered three granite pegmatite lithium polymetallic deposits,i.e.,the Xuefengling,Xuepen,and Shuangya deposits in the Xuefengling area located to the east of the Bailongshan lithium polymetallic deposit in Hetian county,Xinjiang.The Xuefengling lithium deposit consists of 47 lithium polymetallic ore bodies in three ore-bearing pegmatite veins.The ore bodies are 32?360 m long,0.9?8 m thick,with a strike angle of 110°?120°and a dip angle of 49°?78°.The pegmatite vein groups in the Xuefengling area show symmetrical zonation:ore-bearing pegmatite vein group–muscovite pegmatite vein group–bulk quartz feldspar pegmatite vein group–black tourmaline pegmatite vein group–bulk quartz feldspar pegmatite vein group–muscovite pegmatite vein group–ore-bearing pegmatite vein group.High-grade lithium ore bodies were found in the Shuangya Mountain and the Xuepen valley,which are 1550 m south of the Xuefengling.The main ore body of the Shuangya lithium deposit is 850 m long,12 m thick and up to 100 m wide.The Xuepen lithium deposit has three veins,which are 800?1200 m long and 4?8 m thick and form a single ore body with a thickness of 12?20 m.The ores have Li2O grades in the range of 0.6%?4.02%,and the associated BeO of 0.04%?0.15%,Rb2O of 0.10%?0.23%,Nb2O5 of 0.007%–0.047%,and Ta2O5 of 0.003%–0.046%.It is predicted that the Xuefengling,Xuepen,and Shuangya lithium deposits have a total 334 resource of 7.1886×105 t Li2O,2.648×103 t BeO,1.433×103 t Rb2O,3.387×103 t Nb2O5,and 1.727×103 t Ta2O5,which may become a super-large base of lithium polymetallic mineral resource. |
