鄯善县阿其克库都克盆地成煤条件及焦煤远景预测

COAL-FORMING CONDITIONS AND COKING COAL EVALUATION OF PROSPECT IN AQQIKKUDUK BASIN OF SHANSHAN,XINJIANG

对阿其克库都克盆地下二叠统成煤地质条件、古气候、古环境及含煤性、煤质特征和远景预测,进行了实地调查和分析研究.经孢粉鉴定和煤质分析,该区煤系地层时代为早二叠世,煤的变质程度已达焦煤阶段.下二叠统煤系地层的发现,在天山地区尚属首次,可作为一个新的成煤时期引起重视.

At the south edge of Aqqikkuduk Basin, a coal-series strata cropping out about 2km2 has been discoved. There are four minable coal beds in it with average thickness of about 15m. The sporo-pollen analysis indicates that the coal-series strata are of early Permian. The coal content analysis shows that the metamorp-hism reaches the coking coal stage. From analysis of coal-forming condition and later reformation, it is believed that Aqqikkuduk Basin has a bright future in looking for coking coal.
