摘要
鄂西中生代含煤地层素称“香溪群”,典型剖面在秭归县香溪镇。这一煤系早年曾被划分为上三叠统和下侏罗统两部分(谢家荣、赵亚曾,1925)。后来,斯行健(1949)研究了其中的植物化石,认为其时代为早侏罗世,“香溪煤系”始以“香溪植物群”而闻名中外。近年由于工作的深入,不少地质工作者又提出了“香溪群”下部属上三叠统的可能性,但化石却一直没有系统地采集和研究。
The mesozoic coal series in western Hubei was previously named“the Hsiangchi Group”.In his monograph entitled“Die Mesozoische Flore aus der Hsiangchi Kohlen Series in Westhupeh”,Sze(1949)described the fossil plants from there and considered“the Hsiangchi Group”to be Lower Juras-sic in age.Recently,restudies on the stratigraphic sequence and the biota including lamellibranchs,conchostracans,ostracods,megascopic plants and palynomorphs,result in that the“Hsiangchi Group”may be divided into three formations(in ascending order):the Shazhonxi Formation,the Hiangchi Formation and the Qianfuyan Formation.
