摘要

对内蒙古乌达地区下二叠统太原组煤样进行了浸渍处理。它产生了两个角质层碎片和许多传导组织碎片。一个角质层碎片显示出属于蕨类或苏铁的被强烈腐蚀的多角形细胞。第二个片段是具有乳头状四边形细胞的心形背面角质层，可以与Cordaites neimengensis LIU et al. 1998进行比较。传导组织表现为双系至四系的管胞点蚀，这是科塔科动物的典型特征。

Dispersed plant mesofossils from the Permian of Wuda, Inner Mongolia, Taiyuan Formation, China

A coal sample from the Lower Permian Taiyuan Formation (Wuda locality, Inner Mongolia, China) was macerated. It yielded two cuticle fragments and many fragments of conducting tissue. One cuticle fragment shows strongly corroded polygonal cells belonging either to a pteridosperm or a cycad. The second fragment is an abaxial cordaitalean cuticle with papillate tetragonal cells and can be compared to Cordaites neimengensis LIU et al. 1998. The conducting tissue are represented by biseriate to quadriseriate tracheid pitting that is typical for cordaitaleans.

期刊介绍： Geologia Croatica welcomes original scientific papers dealing with diverse aspects of geology and geological engineering, the history of the Earth, and the physical changes that the Earth has undergone or it is undergoing. The Journal covers a wide spectrum of geology disciplines (palaeontology, stratigraphy, mineralogy, sedimentology, petrology, geochemistry, structural geology, karstology, hydrogeology and engineering geology) including pedogenesis, petroleum geology and environmental geology. Papers especially concerning the Pannonian Basin, Dinarides, the Adriatic/Mediterranean region, as well as notes and reviews interesting to a wider audience (e.g. review papers, book reviews, and notes) are welcome.
