中文摘要: 吉中地区发育了普里道利期洛霍考夫期Retziella、杜内期通气沟组以及空谷期沃德期哲斯等腕足动物群。前两者属于暖水动物群、后者属于凉水动物群。同时参考珊瑚和等动物群分析,说明吉中地区从普里道利期至阿瑟尔期发育暖水动物群,从空谷期到沃德期发育凉水动物群。凉、暖转换是以寿山沟组的Monodiexodina动物群为代表,发生在萨克马尔期。凉、暖水动物群的发育及其转换是构造古地理与气候变化双重因素导致的结果。晚志留世早泥盆世,西伯利亚板块、哈萨克斯坦板块、佳-蒙地块均位于中低纬度带。吉中地区晚志留世早泥盆世(乃至中泥盆世)腕足动物群属于暖水动物群,古生物地理区划属于中-澳生物地理区。石炭纪,东欧板块东北缘、哈萨克斯坦板块大部分地区、佳-蒙地块南缘属于特提斯洋北缘构造域,发育了特提斯洋北缘腕足动物群,形成了特提斯北缘生物地理区,吉中地区腕足动物群属于这一生物地理区。空谷期沃德期凉水型哲斯腕足动物群的形成是由于佳-蒙地块西端与塔里木板块以及华北板块西端拼合,形成了西拉木伦洋构造域,以及此时期全球降温事件导致的结果。古生物地理、构造古地理以及古气候之间的协同演化关系表明吉中地区晚古生代地层应属于佳-蒙地块南缘的大陆边缘沉积。
英文摘要: During the Late Paleozoic,brachiopod faunas of Retziella (Pridoli-Lochkovian), Tongqigou Formation (Tournaisian)and Zhesi(Kungurian- Wordian)appeared in central Jilin.Retziella and Tongqigou Formation brachiopod faunas were warm-waterbrachiopods,and Zhesi brachiopod fauna was a cool-waterfauna.Meanwhile,we refer to the characteristics of coral and fusulinid faunas.These show that the faunas of central Jilin from Pridoli to Asselian belonged towarm-water type,and from Kungurian to Wordian belonged to cool-watertype.This conversion from warmwaterto cool-wateroccurred in the Sakmarian, represented by the Monodiexodinafauna of Shoushangou Formation.The development and conversion of warm-waterand cool-waterfaunas were caused by tectonopaleogeography and climate change.During the late Silurian-Early Devonian, the Siberian Plate,Kazakhstan Plate and Jiamusi- Mongolia Block were located at low northern latitudes. The late Silurian-Early Devonian (even to Middle Devonian)brachiopod fauna of central Jilin belongs to warm-waterfauna and its paleobiogeography falls within the China-Australia Paleobiogeographic Province.During the Carboniferous, the northeastern margin of the Eastern European Plate,most areas of the Kazakhstan Plate,and the southern margin of the Jiamusi-Mongolia Block comprised the North Margin of Tethys Ocean tectonic domain and its brachiopods,the North Margin of Tethys Ocean brachiopod fauna, comprised the North Margin of Tethys Ocean Province.The Carboniferous brachiopod fauna of central Jilin belonged to this province.During Kungurian-Wordian,the western margin of the Jiamusi-Mongolia Block probably coalesced with the Tarim Plate and the western tip of the North China Plate to form the Xar Moron Ocean tectonic domain.The formation of cool-waterZhesi brachiopod fauna were caused by the Xar Moron Ocean tectonic domain and global cooling event (Caroo Glaciation). The coevolution between paleobiogeography, tectonopaleogeography and paleoclimate indicates that the Late Paleozoic strata of central Jilin should belong to the southern margin continental deposition of Jiamusi-Mongolia Block.
