摘要
冀南地区煤炭资源丰富,赋煤层位为石炭-二叠系,煤类从无烟煤到气煤,存在非常好的煤类分带现象。煤变质主导作用形成于燕山期中期岩浆活动之后,晚期岩浆活动之前,主导热源体是早、中期岩浆热,煤变质带的展布显示了与构造岩浆活动的一致性。煤变质主导作用是深成岩浆热变质作用。冀南地区干热岩存在很好的找矿前景,武安盆地可以作为首要的勘查对象。
Coal resources in the southern Hebei area are abundant. The coal hosting horizon belongs to the Permo - Carboniferous.Coals ranked from anthracite to gas coal with very good zonation. The main coal metamorphism had arisen between the mid - term andterminal magnetic activities. The main heat source was early to mid - term magmatic heat. The extending pattern of coal metamorphicbelts has shown consistency with teetonomagmatie activities. The leading role of coal metamorphism is the hypogene magma thermo-metamorphism. The hot dry rock in southern Hebei area has quite good prospecting prospect and the Wuan Basin could be the primaryexploration target.
