海拉尔盆地(我国境内部分)位于内蒙古自治区的东北部,是我国东北地区重要的煤炭基地之一.其中伊敏组及大磨拐河组是主要的含煤地层,全盆地稳定发育.通过对矿区样品采集及钻孔资料整理,发现伊敏河东区外围存在明显的镓异常,达到工业可采品位.海拉尔盆地煤中镓的含量整体呈现从盆地东部到盆地西北部逐渐减小的趋势,这可能是受陆源碎屑物、沉积环境不同的影响.海拉尔盆地煤中锗的含量呈现北部地区较高,其他地区较低的趋势.

The Hailar Basin is located in northeastern Inner Mongolia, one of major coal bases in northeastern China. Its Yimin and Damoguaihe formations are the main coal-bearing strata, steadily developed in whole basin. Through mining area sampling, testing, and drilling data processing, have found obvious gallium anomalies in eastern Yiminhe and periphery, up to industrially mineable grade. Content of gallium in coal in the basin presents a trend of gradually decreasing from eastern part to northwestern part as a whole, possibly impacted by different terrigenous clastics and sedimentary environments. Content of germanium in coal in the basin presents a trend of higher in northern part, and lower in other parts.
