四川后高坪地区晚泥盆世植物和遗迹化石的新发现NEW DISCOVERY OF LATE DEVONIAN PLANT AND TRACE FOSSILS IN HOUGAOPING,GUANGYUAN,SICHUAN

摘要(Abstract)：
在扬子板块西缘后高坪地区新发现植物化石Cyclostigma kiltorkense(平圆印木)和Lepidodendropsis hirmeri(希氏拟鳞木),以及遗迹化石Zoophycos(动藻迹)和Chondrties(丛藻迹),据此及相关地层和沉积相标志,确定该地层时代为晚泥盆世,沉积环境为由早期为滨岸较粗碎屑岩和浅海中上部细碎屑岩沉积,晚期为碳酸盐台地相。
