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.
