含铵云母粘土岩夹矸较广泛分布于华北石炭二叠纪聚煤区太原组及山西组煤层中，其可划分为６种类型。文章详细描述了岩石的特征和铵云母在粘土岩夹矸中的赋存特点。测试结果表明铵云母均为１Ｍ型铵云母。它们是由成煤植物和有机质降解形成的ＮＨ４＋离子，促使煤层粘土岩夹矸中的高岭石、伊利石在约１２０℃的酸性条件下转化成的。这种铵云母可以作为煤成气生成和储集的指示矿物。
The ammoniated mica-clay rock gangue is more widely distributed in the coal seams of Taiyuan Formation and Shanxi Formation in the Permian Permian Carboniferous in North China, which can be divided into six types. The article details the characteristics of rocks and the occurrence of ammonium mica in clay rocks. The test results show that the ammonium mica are all of type 1M ammonium mica. They are NH4 + ions formed by the degradation of coal-forming plants and organic matter, resulting in the conversion of kaolinite and illite from the clay rocks of the coal beds under acidic conditions at about 120 ° C. This ammonium mica can be used as an indicator of the formation and accumulation of coal-to-gas.
