| 摘 要： | 黑龙江省西北部发育连续沉积的古生代（O1-C1）地层.结合该地区近年来的区域地质调查和科学研究成果，将该地区奥陶纪-石炭纪岩石地层划分为伊勒呼里山群、黑河群和燎原群3个群15个组，并将各组的岩石建造、化石组合、沉积环境等与古亚洲洋发生、发展、消亡演化历史结合在一起进行论述分析.通过古生代（O1-C1）地层方面的综合研究，为黑龙江省西北部古亚洲洋演化提供了岩石地层、生物地层和沉积环境方面的综合资料.根据上述地层记录，认为古亚洲洋发生于早奥陶世早期，兴盛于早奥陶世晚期-晚奥陶世，收敛期为早志留世-晚志留世-中泥盆世、消亡于晚泥盆世-早石炭世.

| Abstract: | A series of Paleozoic strata(O1-C1) is widely distributed in the northwest of Heilongjiang Province. Combining the regional geological survey and scientific research results in recent years, the Ordovician-Carboniferous strata can be divided into three groups (Yilehulishan, Heihe and Liaoyuan Groups) with fifteen formations. The rock structures, fossil assemblages, sedimentary environments of each formation are discussed together with the open, evolution and extinction history of the Paleo-Asian Ocean. The integrated study on the Paleozoic strata provides such comprehensive data as lithostratigraphy, biostratigraphy and sedimentary environment for the evolution of the Ocean. According to the above stratigraphic records, it is thought that the Paleo-Asian Ocean was opened in the early stage of Early Ordovician, developed in the late Early Ordovician-Late Ordovician, converged in Early Silurian-Late Silurian-Middle Devonian and closed in Late Devonian-Early Carboniferous. |
