【摘要】 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。更多还原

【Abstract】 Plant fossils Cyclostigma kiltorkense and Lepidodendropsis hirmeri as well as trace fossils Zoophycos and Chondrites have been found and described at Hougaoping, Guangyuan City, western Yangtze Plate. The new data and sedimentary facies data indicate that the host strata were deposited during the Late Devonian. The depositional setting evolved from littoral and upper neritic environments to carbonate platform environments.更多还原
