对朝鲜50个煤样中61种元素含量进行测定研究,结果显示朝鲜煤相对地壳高富集元素Li,B,P,As,Se,Cd,Sn,Sb,Hg,Pb等,大多数元素含量均值与美国煤较为接近,与中国煤中元素含量相差稍大,各元素含量基本分布在世界平均范围内,没有发现异常高值,大多数元素在早晚侏罗世、古近纪煤中较其它时期更为富集. The content of 61 elements in 50 coal samples from North Korea was measured and the results showed that the relative abundance of elements in North Korea coal relative to the crust was Li, B, P, As, Se, Cd, Sn, Sb, Hg and Pb, The average value is similar to that of U.S. coal, slightly different from that of coal in China. The content of each element is basically distributed in the world average range, and no abnormally high value is found. Most of the elements are in the early-late Jurassic and Paleogene coal than the other The period is more enriched.
