Abstract
Factor analysis and cluster analysis were applied to the distribution characteristics of ten trace elements in seven Chinese coals. The fact or analysis showed that a three-factor model interprets reasonably the correlations of these trace elements. The results of Q- and R-cluster analysis showed that the seven samples and ten trace elements cluster ed reasonably into different groups. The results can be interpreted by reference to the geochemical properties of these elements.
