辽南金州本溪组下部植物(孢粉)化石的发现

THE DISCOVERY OF FOSSIL PLANTS AND SPOROPOLLENS FROM THE BENXI FORMATION IN JINZHOU REGION OF SOUTH LIAONING

研究了发现于辽南金州地区本溪组下部的植物化石 6属 9种及孢粉化石 15属 2 2种 ,确认其时代为纳缪尔A期 ,较辽东太子河流域本溪组下部发现的植物 (孢粉 )化石的发育时代 (维宪期至纳缪尔 A期 )略晚。这一发现不仅在古植物学和地层学上 ,而且在古地理学及古构造研究等方面都具有重要意义。

Fossil plants and sporopollens collected from the lower part of the Benxi Formation in the Jinzhou region of south Liaoning. There are 9 species of 6 genera of fossil plants and 22 species of 15 genera of sporopollens, the age of the flora being affirmed as Namurian Period, which is later than the Period (Visean to Namurian A) in the Taizihe river valley of eastern Liaoning. The discovery is of essential significance in paleobotanic and stratigraphic study, especially in paleogeographic and paleotectonic studies.
