摘要
吉林省石炭系根据岩性、岩相、沉积类型和生物群性质,以挥发河—古洞河深断裂为界,分为北、南二区。 (一)吉林北区 吉林北区石炭系属天山—兴安地槽型沉积。分布于双阳、永吉、磐石、辉南、怀德、安图、延吉等地。吉中石炭系发育较全,下、上石炭统均有出露,向东上石炭统上部发育良好,向西出露零星。岩性以海相碎屑岩及碳酸盐沉积为主,夹火山岩及火山碎屑岩。
The Carboniferous strata in Jilin may be divided into the northern and southern provinces.The Carboniferous of the northern Jilin is divided ascendingly into the Beitongqigou, Lujuantun, Mopanshan and Shizuizi Formations (The Shanxiuling Formation in the Yanbian region).The biotas in the Beitongqigou Formation consist of brachiopod Fusella-Syringothy-ris Assemblage, those of the Lujuantun Formation are made up of conodont Gnathodus bill' netitus Zone, coral Yuanophyllum Zone, brachiopod Gigantoproductus edelburgensis Assemblage, fusulinid Eostajfella Zone, those in the Mopanshan Formation are conodont Declinogna-thodus noduliferus Zone, fusulind Profusulinella-Pseudostaffella and Fusulinella-Fusulina Zones, coral Lithostrotionella-Lytyophyllum Assemblage and brachiopod Choristites Assemblage.The biotas in the Shizuizi Formation are fusulinid Triticites and Pseudoschtvagerina Zones and brachiopod Dictyoclostus Assemblage.Only the Upper Carboniferous is developed in the Carboniferous of southern Jilin, which is divisible into the Penchi and Taiyuan Formations.The biotas in the Penchi Formation are fusulinid Fusulinella-Fusulina Zone, plant Neuropte-ris gigantea-Linop'eris neuropteroides Assemblage, brachiopod Choristites.Assemblage, and those in the Taiyuan Formation are composed of plant Neuropieris ovata-Lepidodendron po-sthumii Assemblage.
