北山组是1956年建立的。当时,将石人北山村到红石砬一带不整合在奥陶纪马家沟灰岩之上的砾岩称作红石砬砾岩层,整合沉积在红石砬砾岩层上的煤系地层叫北山含煤层。在大石沟里所见的红石砬砾岩和北山含煤层,在岩性、岩相上有明显区别的一套下部为砾岩的含煤地层,称为冷家沟砾岩和冷家沟含煤层,统归中侏罗统。前者成岩深度比后者略高,不含火山岩砾石及火山喷发的物质成分;后者含上述成分。以后,吉林省105队、102队,多次
Kitayama group was established in 1956. At that time, the rocks from Beishancun to Shixia of Shiren were not called conglomerates in the Ordovician Majiagou limestone. The coal strata integrated and deposited on the red rock conglomerate are called coal strata Kitayama coal seam.
