摘要: A number of Triassic (245–195 Ma) alkaline or subalkaline igneous complexes were discovered in the Yan-liao area northern part North China platform. These are all poor SiO2; most them rich Fe, Mg, K and P such incompatible elements as Rb, Ba, U Sr REE; initial 87Sr/ 86Sr ratios range from 0.7055 to 0.7057. They might have originated altered upper mantle. On that basis coupled with distribution System tectonic deformation, it is suggested there should existed a tectono-magmatic belt time, which an important manifestation Indosinian movement area.
