Abstract
The distribution of ash-forming elements and rare earth elements (REEs) in the 2.2-Ulug coal seam and in the coal-bearing rocks of the Kaa-Khem deposit is considered. It was found that ash in unoxidized and semi-oxidized coals was ferruginous–calcium–siliceous and hydrolyzate, HMav = 1.40, and alumina–siliceous siallitic, HMav = 0.49, in oxidized coals. The carbonate composition of the intraformational coal bed was revealed. It was shown that intrusive associations of the Kaa-Khem granitoid batholith were the source of the drift of fragmentary material from the coal-bearing strata.

Kaa-Khem煤矿床中成岩和稀土元素的地球化学
摘要
考虑了灰分形成元素和稀土元素(REE)在2.2-Ulug煤层中和Kaa-Khem矿床的含煤岩石中的分布。结果发现,未氧化和半氧化煤中的灰分在氧化煤中为铁-钙-硅质和水解产物,HM av = 1.40,氧化铝-硅质唾液酸,HM av = 0.49。揭示了内部构造煤层的碳酸盐成分。结果表明,Kaa-Khem花岗岩类岩基的侵入性关联是碎片物质从含煤地层中漂移的原因。
