通过数理统计的方法,计算了渭北晚古生代太原组5号煤层Li等51种微量元素和煤中有机碳、灰分的相关系数,根据对渭北5号煤层Li等51种微量元素-有机碳相关系数平方、微量元素-灰分相关系数平方变化曲线与相应元素的第一电离能、离子半径变化曲线的对比研究,确认煤中微量元素在有机质和矿物质的分布、分配及赋存,总体服从元素周期律,并对此规律作了较完整的理论表述.研究认为,煤的微量元素地球化学周期律至少在鄂尔多斯盆地晚古生代这类统一稳定的聚煤环境里是适用的.
Through mathematical statistics, we calculated the correlation coefficients of 51 kinds of trace elements such as Li and other organic carbon and ash in coal seam No.5 of the Late Paleozoic Taiyuan Formation in Weibei. Based on the analysis of 51 trace elements - Li Correlation coefficient squared, trace elements - ash correlation coefficient squared curve and the corresponding elements of the first ionization energy, ion radius curve of the comparison study to confirm the trace elements in coal organic matter and mineral distribution, distribution and occurrence, the overall compliance Elemental periodic law and make a more complete theoretical expression of the law.The study suggests that the trace element geochemical cycle law of coal is suitable for at least the unified and stable coal-accumulating environment such as the Late Paleozoic in Ordos Basin.
