几十年来,很多地质工作者,对南方各省中生代含煤地层曾做过不少的工作,但由于对地层时代和对比存在着不同的意见,争论很多。十几年前,多数人认为南方各省中生代含煤地层以侏罗纪为主。例如,斯行健(1931)对江西安源煤系,斯行健和李星学(1952)对川东中生代煤系,都认为是侏罗纪的产物,而且斯行健在1949年《鄂西香溪煤系植物化石》一文中,一再说,东京和我国西南部植物与其定为上三迭纪末,总不若定为下侏罗纪较为近事实。这样就对地层的划分影响很大。我在1954年编写《中国标准化石(植物)》中生代部分
For decades, many geologists have done a lot of work on the Mesozoic coal-bearing strata in the southern provinces. However, there are many controversies over the existence of different opinions on the stratigraphic age and contrast. Ten years ago, most people thought that the Mesozoic coal-bearing strata in the southern provinces dominated the Jurassic. For example, Sri Lankan (1931) considered all the Mesozoic coal measures of Anyuan in Jiangxi Province, Anyang Coal Mine of Siyuan and Li Xingxue (1952) as products of the Jurassic. In addition, Coal plant fossils, “one article, repeatedly said that Tokyo and the southwestern part of China and the plant as the end of the Triassic, the total is not determined to be more realistic near the bottom of the Jurassic. This will have a great impact on the stratigraphic division. I wrote the Mesozoic section of ”China Standard Fossil (Plant)" in 1954
