西藏早白垩世多尼煤系煤质特征与煤变质作用初探--以八宿煤矿为例

摘要

西藏蕴藏着丰富的矿产资源，是研究地球形成与演化的重要场所，本文在了解西藏区域煤系特征的基础上，系统搜集整理各种地质资料和研究成果，对西藏早白垩世多尼煤系特征与煤变质作用进行了初步分析，对煤田地质勘查工作提供了依据。%Tibet is rich in mineral resources, and it’ s an important place of studying the formation and evolution of the earth. Based on the understanding of the regional characteristics of coal measures of Tibet, we collects various geological data and research results. and have a preliminary analysis of the char-acteristics and metamorphism of Doni coal measures in Early Cretaceous of Tibet, expect to provide the basis for coal field ge-ological exploration work.
