  • 摘要: 通过对大量煤田(矿区)勘查资料煤中锗含量化验数据的统计分析,以矿区(煤田)为统计单元,确认东北赋煤区主要矿区(煤田)煤中锗含量平均值为1~5 μg/g,均分布在中国煤锗含量平均值附近;即使在典型煤-锗矿床乌兰图嘎所在的胜利煤田和五牧场所在的伊敏煤田,统计煤中锗平均值分别为2.63 μg/g和3.30 μg/g,没有明显的升高,胜利、伊敏煤田其他井田,煤中锗含量平均值均与中国煤中锗含量平均值相差不大,煤中锗的富集表现为在小范围内聚集;煤中锗富集区域常可见热液矿物,结合前人对典型煤-锗矿床的研究,认为煤中锗主要由热液携带进入,热液侵入为煤中锗的富集提供了有利条件。本次工作在二连、海拉尔盆地新发现一批煤中锗异常点,由于煤中锗的富集通常范围较小,已有煤田勘查资料显示有未能控制到锗富集的范围,这些异常点很值得做进一步工作。
