| 摘 要： | 对鲁西地区石炭二叠纪煤系火山碎屑岩特征进行了分析，结果表明，火山碎屑物质以晶屑最为常见，常见的火山碎屑岩有凝灰岩、沉凝灰岩、凝灰质灰岩、凝灰质砂岩、为质砂岩、凝灰质粉砂岩。还对在太原组煤层中发现的宇宙尘形貌及化学组成进行了研究，哟与国内外相关资料对比，认为研究区宇宙为Ｓｉ质玻璃球。提出了研究区石炭纪生过火山地质事件、天体地质事件。

| Abstract: | The characteristics of efflata in the Permo carboniferous coal bearing measures of the western Shandong are analyzed.The results show that pyroclasts are dominated by crystal clasts.The main volcanic arenites include tuff,sedimentary tuff,tuffaceous lithoclast,tuffaceous sandstone and tuffaceous siltage.The shapes and chemical components of cosmic dust in the coal layers of Taiyuan group are studied.Compared with the related materials nationlly and internationally,the cosmic dust in the study area can be considered as siliceous glass bead.In addition,this article puts forward that volcanic and asrtogeological events happeded in the study area in Carboniferous period. |
