The SIMS measurements gave ages of 134¨C159 Ma. Its average of (144.5¡À6.2) Ma is interpreted as the best estimate of the pyroxenite intrusion. The crystallization of zircons continued for quite a long time and underwent slow cooling. The pyroxenites are products of post-collision magmatism. The REE pattern is HREE-enriched, and its HREE concentrations fall between the magmatic and metamorphic range of gneissic zircons from the Dabie area, which indicate the involvement of crust material in its mantle source. %K zircon SIMS age %K zircon trace element %K crust-mantle interaction %K Northern Dabie pyroxenite %U http://link.springer.com/article/10.1007/BF03183556
