新疆阿舍勒、冲乎尔地区泥盆纪岩相古地理研究

新疆阿舍勒、冲乎尔地区泥盆纪地层以火山岩为主，伴有陆源碎屑岩和内源沉积岩。对其古地理面貌的恢复，只有采用特殊的研究思路才能实现。缘于此，本文采用成因相和环境相的研究思路，对该地区的岩相古地理面貌做了较为详细的研究和恢复，为如何在火山沉积盆地中进行古地理研究提供了思维方法和工作模式。

SEDIMENTARY FACIES AND PALAEOGEOGRAPHY OF THE DEVONIAN STRATA IN THE ASHELE AND CHONGHUR REGIONS,XINJIANG

The volcanic rocks associated with the terrigenous elastic rocks and intrabasinal sedimentary rocks predominate in the Devonian strata in the Ashele and Chonghur regions,Xinjiang.According to the viewpoint of the genetic factes and environmental factes, five types of genetic factes and five types of environmental factes may be recognized for these regions.The former comprise volcanic factes,tempestite factes,volcanic gravity flow facies,volcanic turbidity current factes and terrigenous clastic turbidity current factes,and the latter include abyssal-subabyssal factes,shallow shelf facies,littoral and shallow marine factes, organic reef or bank factes and restricted platform factes. The detailed study of sedimentary factes and palaeogeography of the Devonian strata in the study area allow the mode of thinking and working models to be proposed for the study of sedimentary factes and palaeogeography in the volcanic-sedimentary basins.
