敖振宽等同志在“论岳麓砂岩”一文中,通过对古植物、沉积旋迴、古地理和地壳运动等方面的研究,指出在湖南分布颇广的岳麓砂岩与雪峰砂岩基本上为同时沉积,均为上泥盆世末到下石炭世初,约与欧洲的Etroeungtian期相当。并进而将岳麓砂岩与东南各省的五通系对比,认为“岳麓砂岩大致与五通系、珞珈山石英砂岩、峡山系等相当,虽然后者可能时代会略早于岳麓砂岩,但我们认为它们基本上还是可以对比的”。这个结论,笔者认为还值得商榷。
Ao Zhenkuan and other comrades in the “on the Yuelu sandstone” article, through the study of ancient plants, sedimentary cycles, palaeogeography and crustal movement and other aspects, pointed out that in Hunan quite widely distributed Yuelu sandstone and Xuefeng sandstone basically at the same time Sedimentary, both from the end of Upper Devonian to the lower Carboniferous, is about the same as the Etroeungtian period in Europe. And then compares the Yuelu sandstone with that of the five provinces in the southeastern provinces. It states that “the Yuelu sandstone is roughly equivalent to the five-way system, Luojiaoshan quartz sandstone and the Xiashan system. Although the latter may be slightly older than the Yuelu sandstone, Think they are basically comparable. ” This conclusion, I think it is also debatable.
