滇西镇安盆地泥炭、软褐煤的煤岩学研究

COAL PETROLOGICAL INVESTIGATION INTO THE PEAT AND SOFT—BROWN COAL FROM THE ZHENAN BASIN, WESTERN YUNNAN

研究结果表明,ICCP颁布的褐煤显微组分命名及分类方案基本上可以用来描述泥炭、软褐煤,泥炭,软褐煤中有微粒体存在。部分碎屑惰性体可能直接来自于植物体内。发绿至绿黄色荧光的稳定组分的I_546为负变化;而发深黄至橙红色荧光的稳定组分的I_546则为正变化。某些无荧光或溺荧光的腐植体在兰光激发一段时间后会产生荧光或荧光变强;随激发时间的进一步延长,有的甚至会发较鲜艳的黄色荧光,I_546也明显增大。图8,表1,参4。

The peat and soft—brown coal from the Zhenan basin.western Yunnan. has been studied in detail by means of coal petrology.The nomenclature of the macerals of brown coal promulgated by ICCP might be used as the basis for describing the macerals of the peat and soft—brown coal. There exists the micrinite in the peat. Some of humodetrinites might from within plants themselfs. The liptinites with green to greenish—yellow fluorescence change negetively in I_(546),however,the other liptinites with dark yellow to orange—red flourescence positively.After being stimulated for a while by blue flourescence, some huminites with anything but flourescence or weak flourescence would emit flourescence,or their flourescence would become stronger,and when being stimulated further,some of the above huminites would emit fresh yellow flourescence and the I_(546) would become larger.8 figs.,1 tab.,4 refs.
