%X Chang 2 sandstones of Yanchang formation (upper Triassic) in Yanchi-Jiyuan area, southwest Ordos basin, are a set of distributary channel and mouth bar sandstone bodies formed in delta front facies, and mainly composed of lithic feldspathic sandstone and feldspathic sandstone, of which the average content of quartz , feldspar and lithic fragments accounts for 32.6%, 38.9% and 8.0%, respectively. Metamorphic and igneous rock fragments are main lithic constitutes, accounting for 87.5% of the total fragments. ...
