朝鲜煤中元素含量及分布
Concentration and distribution of elements in coals from DPR Korea
【摘要】 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.
【Abstract】 The concentrations of sixty one elements in DPR Korea coals were determined.The studies show that elements Li,B,P,As,Se,Cd,Sn,Sb,Hg,Pb are highly enriched DPR Korea coals.The means of elements in DPR Korea coals are closer to American coals than Chinese coals,and most elements contents are distributed in the average ranges of world coals.No abnormally high values are found in DPR Korea coals.Most elements are more enriched in late Jurassic and Paleogene coals than the other coal-forming ages.
