| 摘 要： | 甘肃省金塔县北部（紫山子地区）含煤地层,由于地质工作程度低,古生物资料比较缺乏,对含煤地层时代认识尚不一致。为解决含煤地层时代及探讨找煤前景,在所选剖面的不同层位中采集到少量古植物化石及孢粉样品。古植物化石鉴定为早中侏罗世常见分子;孢粉样品经分析获得了较为丰富的化石,经研究并与时代相当的孢粉组合对比,确定当前组合时代为中侏罗世。

| Abstract: | There are different opinions on the coal-bearing strata age in northern part of the Jinta County,Gansu Province,due to lack of sufficient paleontologic materials.During the Gansu Provincial Coal Geological Exploration Institute did 1/50000 geological mapping and coal exploration in this area,in order to identify some issues on the age of coal-bearing strata,a few fossil plants and sporopollen fossil samples had been collected.The conclusion of the fossil plant identification considered that the plants shoul... |
