摘　　要：对邯郸三陵地区二叠系石盒子组黏土岩进行薄片光学显微镜和电子探针分析,利用X射线荧光法测试其主量元素,利用电感耦合等离子体质谱法分析其微量元素。结果表明:(1)黏土岩主要矿物是伊利石、石英、叶蜡石、鲕绿泥石和钠长石,类似青磐岩矿物组合,副矿物有黄铜矿和微量的闪锌矿、独居石及锆石;(2)黏土岩稀土元素异常富集,以轻和部分中稀土元素富集最为强烈,可能是热液流体改造的结果;(3)黏土岩具有潜在的资源化利用价值。The claystone from Permian Shihezi Formation in Sanling area,Handan,was analyzed for minerals by using optical microscope and electronic microprobe analyzer （EMPA）,for major elements by using X-ray fluorescence spectrum （XRF） analyzer,and for trace elements by using inductively coupled plasma mass spectrometry （ICP-MS） analyzer. The result shows that,（1） the claystone is composed of illite,quartz,pyrophyllite,chamosite and albite,with a trace amount of chalcopyrite,monazite and zircon,and such a mineral assemablage is similar to propylite;（2） the claystone is abnormally enriched in rare earth elements （REE）,especially in light ones and some middle ones,which is probably the result from a hydrothermal action;and （3） it is valuable as a potential resource.
