Abstract A black shale sample collected from the Chimiari site (Tarbela) was analyzed for elemental contents. Inductively coupled plasma-optical emission spectrometry (ICP-OES) was employed to determine major and trace elements in the digests. Precise analysis was accomplished for the black shales, which was better than 2.0%. Result shows that the shales are very rich in Ca (25439 mg∙g-1), Fe (13933 mg∙g-1), Ti (6932 mg∙g-1), Al (5993 mg∙g-1) and K (2730 mg∙g-1).
Key words black shale; ICP-OES; trace element
