摘　　要：黑龙江东部桦南县创业屯稀有金属矿点位于兴蒙造山带佳木斯地块,大地构造位置属于密山-宝清陆缘弧盆-裂陷盆地以及马家弧盆。区内已经发现了36条伟晶岩脉,其中包括稀有金属矿体5条,稀有金属矿化体2条。赋矿岩性为白云母石英伟晶岩、钠长石伟晶岩、锂辉石英伟晶岩、块体石英伟晶岩,多见白云母化、钠长石化、云英岩化、锂云母化。含矿伟晶岩的形成与分布受多种地质因素影响,其中韧性剪切带的活动起到了至关重要的作用。伟晶岩脉具有沿炭质板岩片理方向侵入的特性,其形成、富含稀有金属的特征,与韧性剪切带的构造活动及其与周围地层的相互作用密切相关。The rare metal mine of Chuangyetun in Huanan County,eastern Heilongjiang Province is located in Jiamusi block of Xingmongol Cenozoic orogenic belt,and its tectonic location belongs to Mishan-Baoqing continental margin arc basin-rift basin and Majia arc basin.Recently,36 pegmatite veins have been found in the area,including 5 rare metal ore bodies and 2 rare metal mineralized bodies.The ore-bearing rocks are muscovite quartz-pegmatite,albite pegmatite,spodumene pegmatite,bulk quartz-pegmatite,mostly containing muscovite,albitization,dolomitization and lepidolite.The formation and distribution of ore-bearing pegmatite are affected by many geological factors,among which the activity of ductile shear zone plays a crucial role.Pegmatite dike is an intrusion along the direction of the carbonaceous slate schism,and its formation and rare metal-rich characteristics are closely related to the tectonic activity of the ductile shear zone and its interaction with the surrounding strata.
