摘　　要：对晋冀交界地带燕山期黑崖岩体的稀土元素特征研究 ,初步判断其源岩可能是具陆壳性质的岩石。利用非实比平衡部分熔融公式对岩石成因作了稀土元素定量模拟 ,提出本区花岗岩类的源岩可能是阜平地区广泛分布的新太古代变质深成岩—坊里片麻岩。The initial judgment that source rock of Yanshanian Heiya rock mass, on the border of Shanxi and Hebei, may have land shell properties, comes from the studying on characteristices of its rare earth element. By using part melt formula of non real proportion balance,rare earth element quantitive imitation of rock forming reason was made. Thus source rock of the granide may be Neoarchean metamorphic deep seated rock Tuoli gneiss, widely distributed in Fuping area.
