评“河南西峡盆地产恐龙蛋地层研究新进展”

Comment on “New progress in the study of the dinosaur eggs-bearing strata in Xixia Basin, Henan”

＂河南西峡盆地产恐龙蛋地层研究新进展＂一文主张用＂走马岗组＂、＂赵营组＂和＂六爷庙组＂来替代正式命名的一套地层名称，这样做既不符合地层命名原则，又易引起新的不必要的混乱。在晚白垩世时西峡、淅川两盆地在岩性组合特征上是相似的，浙川盆地并不是＂岩性特征简单＂，西峡盆地也不是＂岩性复杂＂。西峡盆地晚白垩世＂红层＂应采用＂高沟组、马家村组和寺沟组＂这套地层名称。

Since the fossil dinosaur eggs were found from the Late Cretaceous 'red beds' of Xixia Basin in 1974, this suite of 'red beds' have been formally named hi Zhou Shi-quan and others (1983) in ascending order: the Gaogou, Majiacun and Sigou Formations, and have been widely accepted from that time. At present, Cheng Zheng-wu and others (1995) advocate replacing the above-mentioned formal names with the Zoumagong, Zhaoying and Liuyemiao Formations, which were proposed by the Petroleum Geological Team of Henan Geological Bureau in 1960 and then abandoned themself in 1961 in their unpublished geological reports. Such a doing is not in conformity with the Stratigraphic Nomenclature and also leds to an unnecessary confusion. The geologic structure, formation and evolution of the basin, sedimentary facies and their distribution, the types of fossil dinosaur eggs and their distribution, the underlying strata, and the history of the stratigraphic division and correlation are briefly dealt with in this paper.
