摘要: 1990 年在东河1井发现了“东河砂岩”,1993年又在草湖地区草2井找到胴甲鱼化石。经过近几年的古生物地层学的研究, 人们先后找到了石炭-泥盆系界线附近的牙形石、孢粉化石, 从而将“东河砂岩” 划归泥盆系, 被大家所接受。近期,在塔中45 井发现泥盆纪鱼类化石, 使得塔中地区“东河砂岩”划归泥盆系有了更充分的证据。

Abstract: Since “Donghe sandstone" had been found in Well Donghe 1 in 1990, antiarcha fossil was found in Well Cao 2 of Caohu area in 1993.Based on paleontology and stratigraphy studies in recent years, conodont and sporopollen were successively found nearby boundary of Carboniferous-Devonian, so “Donghe sandstone" is put in Devonian.Discovery of Devonian fish fossil in Well Tazhong 45 offered reliable evidence for “Donghe sandstone"belonging to Devonian in Tazhong area.
