| 摘 要： | 文章采用野外露头、钻井地质相结合的分析方法，讨论了新疆北部石炭纪的岩相古地理环境。野外露头、钻井资料的沉积建造、沉积相分布及古生物组合特征综合表明，新疆北部石炭纪古地理总体特征表现为由早石炭世的深海-半深海相、浅海相向晚石炭世的浅海相、海陆过渡相及陆相演化的趋势。岩石组合类型由早石炭世的活动陆缘型岛弧火山岩、深海复理石及海相碳酸盐岩向晚石炭世的裂谷型火山岩、陆相碎屑岩、海相碎屑岩及海相碳酸盐岩过渡。早、晚石炭世不同地区的古地理及其相应的岩石组合类型存在明显的差异。

| Abstract: | The Carboniferous lithofacies paleogeography in Northern Xinjiang was discussed by the combination of analysis on the outcrop and well profiles of volcanic rocks. The comprehensive study of borehole data, sedimentary facies, sedimentary construction, and Paleontology combination indicates that the overall characteristic of Carboniferous paleogeography in northern Xinjiang evolved from deep sea-half deep sea facies and shallow sea facies in the Early Carboniferous to the shallow sea facies, sea-land transition facies and continental facies in the Late Carboniferous. Rock association types transited from active epicontinental island-arc volcanic rock, abysmal flysch and marine carbonate rock in the Early Carboniferous to riftogenic volcanics, terrestrial clastic, marine clastics and marine carbonate rock in the Late Carboniferous. The tectonic lithofacies paleogeography and rock associations have distinct difference in different regions between Early and Late Carboniferous. |
