云南潦浒第三纪褐煤盆地白泡煤成因特点

云南潦浒褐煤盆地白泡煤在煤层结构、煤岩组分及物理化学性质等方面有着显著的特点，对其分类地位和成因一直存在较大争议作者运用煤岸学、煤化学方法及电子显微技术（选区电子衍射SAD及暗场DF方法）对白泡煤显微组分特征、降解组分超微结构和腐植酸组成等做了系统对比研究。研究结果进一步验证了潦浒白泡煤是以草本植物为主体的草本—木本植物组合体在中位沼泽环境中形成的推论。

THE COAL-FORMING CHARACTERISTICS AND GENESIS OF BAIPAO COAL-FROM TERTIARY IN LIAOHU, YUNNAN PROVINCE

Characteristics studies on the macerals, dgudation macerals and humic acid of Baipao coal -from Tertiaryin Liaohu, Yunnan province are made in this paper by the methods of coal petrographic, coal-chemists and TEM(selected area diffraction - SAD and dark field - DF) technolop. We also make a systernaically study of Baipao coalcompared with the dark brown coal.It is proved up to the hilt that the Baipao ccal coal-forming environment aremiddle moor.
