摘要

In this paper, the organic affinity of residual hydrocarbon and trace elements in mid-rank coals from the Weibei coalfield of Shaanxi Province was examined by correlation analysis, and the authors put forward the concept of affinity coefficient. The results show that the distribution of trace elements in the Weibei coalfield shows obvious regularity among organic matters, minerals and various kinds of organic components. It is also shown that the correlation between trace elements and organic carbon/S₁ is relatively weak in Weibei coalfield, which is different from those of the Junggar coalfield in Xinjiang.
