本文给出了内蒙古色尔腾山区下佘太组至拴马桩组、太原西山煤田本溪组至山西组和安徽淮南煤田山西组至上石盒子组等52个煤层的碳同位素数据。这些煤层均为腐植煤,不同煤层的δ~(13)C值在-26.20‰～—22.10‰之间波动,均值为-24.16‰,与我国各时代煤的δ~(13)C均值(-24.4‰)十分接近,但明显有别于冈瓦纳煤和藻煤(其δ~(13)C值分别为-22.70‰和-30.80‰)。上述三地煤中δ~(13)C值包括从纳缪尔(Namurian)晚期至卡赞期(Kazanian)的各地质时段。按各煤层所在岩组的地层对比关系组构的华北石炭纪—二叠纪煤的碳同位素地层学型式表明。δ~(13)C值在斯蒂芬期(Stephanian)、亚丁斯克期(Artinskian)和卡赞期呈现大约2.5‰～3.0‰的负迁移,这种负迁移与煤级、煤的显微组分及成煤植物种类可能无关,而是优势成煤植物(乔木状石松类)所记录的环境大气CO_2的碳同位素组成之变化,煤与有机物、碳酸盐岩的碳同位素组成的变化一样,可用地球碳存储体的大规模过程来解释。陆—陆碰撞对全球碳循环起主导作用,石炭纪、二叠纪,是全球各主要陆块
This paper presents the carbon isotope data of 52 coal seams, including She She Tai Group to Tiema Pile Group in the Serteng Mountains of Inner Mongolia Autonomous Region, Benxi Formation to Shanxi Formation in the Taiyuan Xishan Coalfield and the Shanxi Formation to the Upper Shihezi Formation in the Huainan Coalfield in Anhui Province. The δ13C values of different coal seams fluctuate between -26.20 ‰ and -22.10 ‰, with a mean value of -24.16 ‰, which is consistent with the δ ~ (13) C average (- 24.4 ‰) is very close, but obviously different from Gondwana coal and algal coal (the δ ~ (13) C values are -22.70 ‰ and -30.80 ‰, respectively). The δ ~ (13) C values of the above three coal types include various geologic time periods from the late Namurian to the Kazanian. The carbon isotopic stratigraphic patterns of the Carboniferous-Permian coal in North China, organized according to stratigraphic correlations of the rock groups in each coal seam, are shown. The δ ~ (13) C values show a negative migration of about 2.5 ‰ ~ 3.0 ‰ in the Stephanian, Artinskian and Kazan periods. The negative migration is related to the coal rank, the microstructure of the coal, The type of coal-bearing plants may not be related, but the change of carbon isotope composition of the atmospheric CO 2 recorded by the dominant coal-forming plants (arcuate pine). As the change of carbon isotope composition of organic matter and carbonate rock, Carbon storage process to explain the large-scale process. Land-land collision plays a leading role in the global carbon cycle. Carboniferous and Permian are the major land masses in the world
