一、前言福建中生代含煤地层广泛分布于西南部、中部和北部。东南沿海一带仅有另星分布,而且多已变质。对于该地层的研究早在三十年代初即已开始。王恒升等(1930)在闽北建瓯上樟垅地区梨山创“梨山煤系”;王绍文等(1930)创“龟岭砂岩”;南延宗等(1941)又创“茫汤洋砂页岩”等。后来,通常把这一含煤地层统称为“梨山煤系”,时代定为早侏罗世。斯行键对长汀珠山的煤山的植物群作了专门研究,定其时代为早侏罗世的里阿斯阶。这样,“梨山煤系”的地质时代就从古植物方面得到了肯定。并为省内外广大地质工作者所引用。
First, the preface Fujian Mesozoic strata are widely distributed in the southwest, central and northern. Southeast coast of only another star distribution, but more than deterioration. The study of this formation began as early as the early 1930s. Wang Hengsheng et al. (1930) founded “Karstang Sandstone” in the Shangshangtu area of Jian’ou in northern Fujian Province; Wang Shaowen et al. (1930) Shale “and so on. Later, this coal-bearing formation was generally referred to as the ”Lishan coal measure,“ and the era was designated as Early Jurassic. The key to the Changtingzhushan Meishan flora made a special study, set its age as the early Jurassic rias order. In this way, the ”Lishan Coal Measures" geological era has been affirmed from the ancient plants. And for the general geological workers inside and outside the province cited.
