安徽两淮地区为我国重要的煤炭基地之一。作者在砀山梁寨H210.H013钻孔样品中发现了丰富的孢粉化石,为该区地层的划分充实了依据。按孢粉组合特征本区石炭—二叠系可划为本溪组、太原组、山西组、下石盒子组、上石盒子组。同时可将有争论的上、下石盒子组的界线,置于FF013—18与FF013—20之间的厚层石英砂层的底部。

Liang-Huai Region in Anhui province is one of the important coal bases of China. Abundant sporopollen fossils were found in core samples of well H210 and well H013 taken from Liangzhai, Dangshan, which provide the basis for stratigraphical division of that region. According to the chara-cteristics of sporopollen assemblages, Permo-Carboniferous system of that region could be divided into Benxi Group, Taiyuan Group, Lower Shihezi Group and Upper Shihezi Group. In addition, the disputed boundary between upper and lower Shihezi groups put here on the bottom of thick quartz sands between FFO13-18 and FFO13-20.
