| Abstract: | Inggen-Ejin Qi Basin in the Early Cretaceous volcanic eruptions strongly, forming a set of basic volcanic rocks. Samples collected in the field by the geochemical analysis of volcanic rocks belong to high-K basalt Suhongtu. According to the study area volcanic geochemistry of volcanic rocks derived from enriched mantle in the formation process has not experienced significant crustal contamination. Finally, the northern margin of the North China craton, volcanic regions were compared by study area and is located in the northern margin of North China plate Yixian Formation in western Liaoning Siziwangqi and geochemical characteristics of volcanic rocks of comparative study that across four different nature of the earth structural units of silver - the amount of land is a pro-North China Basin by, or under that have a similar independent and North China plates enriched mantle source. |
