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 (C3j）”。1982 年笔者在“金沟组”的钙质泥岩薄夹层中采得了古鲤鱼类(Palaeoniscidae)化石,同时 在鱼化石层中还采得近卵形小徽体蚌 ［Microdontella subovata (Jones)]，故认为“金沟组”的时代应为晚二叠世。根据“金沟组”中抱粉分析成果,证实“金沟组”与平地泉组（P2p）为同时异相沉积, 故“金沟组”应予废弃,正名为平地泉组。

Abstract: Mr. Peng Xiling gave a name "Jingou formation" (C3j) for a set of strata in east side of Shiqianta n in Kela meili area of Junggar basin in 1980. The author found Palaeoniscoidea fossil in ca lareous mudstoneth in interca lated bed of "Jingou formation" in 1982, and fou nd Microdotella suvote (Jones) in the fossil bed in the same ti me, so it is considered that the age of "Jingou for mation" should be late Permian. Based on the ana ly-sis results of sporopollen, it is confirmed that "Jingou formation" and Pingdiquan formation (P2p) are in the same time, but sediments of different facies, so the "Jingou formation" should be renamed Pingdiquan formation.
