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。
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.
