摘　　要：新疆阿勒泰地区煤炭资源的研究开发程度较低。以区域地质、煤田地质资料为基础,结合遥感、物探等资料,通过对重点含煤区进行野外地质调查,对阿勒泰地区侏罗纪煤系赋存特征进行了研究。结果显示:该区侏罗纪煤系均赋存在准噶尔板块内;含煤盆地类型为大型内陆坳陷盆地和小型山间断(坳)陷残留盆地,且内陆坳陷盆地成煤环境优于山间断(坳)陷残留盆地。最终圈定了卡姆斯特、奥塔乌开给什、青格里、哈拉通沟、迪伦山-喀拉玛盖、托斯特-乌伦古6个(预测)含煤区。Altay area in northern Xinjiang has high development degree of metal mineral resources,however,coal resources in the area have been less investigated and developed.Study of the coal-bearing characteristics in this area is of great significance.On the basis of regional geology,mineral geology（mainly coal）,collected remote sensing and geophysical data,and geological survey for major coal-bearing areas,the authors carried out a general study on the occurrence characteristics of Jurassic coal-bearing measures in Altay area,discussed in brief the distribution and coal occurrence characteristics of the Jurassic coal-bearing measures in different tectonic units.The results of the study indicated that all Jurassic coal measures are located in Junggar plate,coal-bearing basins are large inland depression basins and small intermountain fault subsidence（depression） residual basin,and coal-forming environments in inland depression basins are better than those in intermountain fault subsidence residual basin.Finally,six（prospective） coal-bearing areas were delineated,providing valuable technical reference for future coal resources survey in Altay area.
