Abstract: The Xifeng intrusive body occupies an important position in the geology of Liaoning, for not only its huge exposed area, but also the rich mineral resources associated with it. The intrusive body was once regarded as one of the biggest rock bodies in Liaoning Province, where it covered an area over 1200 km² and extended to Jilin Province. The related minerals involve iron, copper, lead-zinc-silver-gold-molybdenum polymetal and fluorite. On the basis of petrology, petrogeochemistry, isotopic chronology and the contact relations between rock masses and between rock mass and strata, the Xifeng intrusive body in Liaoning is disintegrated by the tectono-magmatic evolution stages. Four intrusion stages with total 11 intrusion orders are divided, including three Early Permian, one Early Triassic, three Middle Jurassic and four Late Cretaceous orders of intrusion. With this division, the lithological metallogenic specificity, the genetic types and oreforming stages of deposits are studied to guide the prospecting work for Xifeng area in the future.
