Distribution and significance of “barkinite” in Mowo coal mine of Han-Xing coalfield, North China

In order to study the distribution and significance of “barkinite” in the Han-Xing (Handan-Xingtai) coalfield, northern China, 140 samples were collected from 10 coal mines and then analyzed by maceral separation, Rock-Eval and microscopic method. The results indicate that “barkinite” can be observed in samples from only three mines with a value lower than 2%. The “barkinite” from the Mowo mine was studied in detail because of its relative high content of “barkinite”. In addition, the HI value of “barkinite” is higher than that of the coal seam as a whole, showing that “barkinite” has considerable potential for hydrocarbon generation.
