This paper researches the geological environment of the Late Carboniferous epoch volcanic rocks in Luliang area, and to support the final closing time of Junggar Ocean and the geotectonic evolution in Junggar Basin. Based on the samples’ chemical analysis data, major elements, trace elements and REE, a research is made in Luliang area. The volcanic rocks in the study area are dominated by basalts with a small amount of rhyolites, andesites and dacites. Carboniferous volcanic rocks from Luliang uplift in Junggar Basin are formed in the continental rifting environment.
