Seven sedimentary rock reference samples from Estonia
The major oxide and trace element compositions of seven sedimentary rock reference samples (claystone, organic-rich argillite, two limestones, dolostone, sandstone and feldspathized volcanic ash) are presented. Among studied samples the organic-rich argillite ("Dictyonema shale") is conspicuous for wide range of chemical elements with higher contents than in common sedimentary rocks. The content of 68 elements and components has been determined.
