摘　　要：汉儿庄岩体是河北省少见的碱长花岗岩型稀有金属矿化岩体,其灰白色碱长花岗岩全岩铌钽铷矿化。目前区内工圈定2条铌钽矿体,估算潜在资源量铌钽约10万余吨,找矿潜力巨大。推测矿床成因为起源较深的花岗岩浆经过较充分的分异演化晚阶段的产物,作为中国北方少见全岩稀有金属矿化型岩体,具有较好的研究意义及突破潜力。Hanerzhuang lithesome is an alkali-feldspar-granite-typed rare metal mineralized pluton,rare in Hebei Province,and whole body of grayish white alkali occurred niobium-tantalum-rubidium mineralization.At present,two niobium-tantalum orebodies were selected in the area,and the estimated potential resource was about 100000 tons of niobium-tantalum,which indicated huge prospecting potential.It was speculated that the deposit was the product of the late-staged differentiation and evolution of granite magma with deep origin.As an infrequent whole-rock rare metal mineralized rock mass in northern China,it has good research significance and breakthrough potential.
