Jurassic coal in NW China is named as “coal with good quality” with huge reserve and perfect coal quality, mostly with low ash content and low sulfur content. The coal petrology and its geological controlling factors are discussed. The kind of coal is largely different from Carboniferous-Permian coal in eastern China and foreign “Gondwanic coal”. Jurassic coal in NW China is the product of large-scale inland-type basin evolution with unique coal types. Most of Jurassic coal in NW China belongs to low-metamorphism bituminous coal, with small-scale medium and high-metamorphism bituminous coal and non-bituminous coal in local area with a mining point of lignite.
