摘要
通过已有资料,对雅布赖盆地进行找煤探索性勘查.结果表明,在中-下侏罗统芨芨沟组(J1j)-龙凤山组(J2l)下部发现了工业煤层.该盆地属北山—阿拉善盆地群中的一个次级盆地,是早侏罗世晚期开始形成的一个断陷盆地,广泛沉积了煤系地层,在河流至湖泊过渡相形成煤层.雅布赖盆有较好的找煤前景。
Through existing data on Yabrai basin and coal prospecting,the industrial coal bed was found under the region of Jijigou group（J1j）-Longfengshan（J2l） in middle-lower times of Jurassic.The basin is a sub-basin of Kitayama-Alashan basin groups,and it formed to rift basin in the late of early Jurassic with extensive deposition of coal series stratum,and formed coal bed at the transitional phase of lakes to rivers.The results show that coal prospecting looks good in Yabrai basin,and it＇s basis to coal prospecting in Yabrai basin.
