摘　　要：１９８０年彭希龄在准噶尔盆地克拉美丽地区石钱滩东侧命名了一组地层为“金沟组（Ｃ＿３ｊ）”。１９８２年笔者在“金沟组”的钙质泥岩薄夹层中采得了古鳕鱼类（Ｐａｌａｅｏｎｉｓｃｉｄａｅ）化石，同时在鱼化石层中还采得近卵形小微体蚌［Ｍｉｃｒｏｄｏｎｔｅｌｌａｓｕｂｏｖａｔａ（Ｊｏｎｅｓ）］，故认为“金沟组”的时代应为晚二叠世。根据“金沟组”中孢粉分析成果，证实“金沟组”与平地泉组（Ｐ＿２ｐ）为同时异相沉积，故“金沟组”应予废弃，正名为平地泉组。Mr. Peng Xiling gave a name“Jingou formation”(C_3j)for a set of strata ineast side of Shiqiantan in Kelameili area of Junggar basin in 1980.The author foundPalaeoniscoidea fossil in calareous mudstone thin intercalated bed of”Jingou formation" in1982,and found Microdotella subvote(Jones)in the fossil bed in the same time,so it isconsidered that the age of" Jingou formation" should be Late Permian. Based on the analy-sis results of sporopollen , it is confirmed thatqingou formation" and Pingdiquan forma-tion(P_2p )are in the same time,but sediments of different facies,so the " Jingouformation" should be renamed Pingdiquan formation.
