Abstract: There are ultramafic rocks in Tuquan Mangniuhai, Inner Mongolia. The main rock types are serpentine peridotite,pyroxene peridotite,diallage peridotite,and serpentinite. Under a microscope,the"spinifex"structure is visible,and the columnar hollow skeleton crystal structure in the fake image of serpentine, fishbone, or pinnate structure as well. The petrochemistry is characterized by high Mg (w(MgO)33.63%-39.44%),Cr(2 200×10-6-17 200×10-6),and Ni(1 900×10-6- 3 000×10-6); high CaO/Al2O3(0.56-39.01, an average of 7.05);low Ti (w(TiO2) 0.01%-0.02%),Al (w(Al2O3)0.03%-0.36%),and alkali (w(K2O+Na2O) 0.03%-0.65%), similar to that of komatite. The average forsteritic index (87) closes to that of dunite (86); w(∑REE)(0.32×10-6-2.79×10-6)is significantly lower than that of ocean ridge, and the LREE/HREE (2.80-16.68) show LREE enrichment with a positive Eu anomaly; the rock is enriched in large ion lithophile elements (LILE) Rb, Ba、Sr, while it is depleted of high field-strength element (HFSE) Nb, P. The results indicate that the mafic magma originated from the depleted asthenosphere mantle, and was altered by subduction in an island arc tectonic environment. The Mangniuhai ultramafic rocks with those in Tuquanweichang, Haolaoluchang, Chaorihaiwula, Meilaotewula Erdaojing of Sonid Left Banner constitute a nearly East-West ultramafic rocks (ophiolite) belt. Based on the analysis of the geological formation, the authors conclude that the structural belt may be the final suture zone of the North China plate and the Siberia plate.

Key words: Inner Mongolia, Mangniuhai, ultramafic rock, petrogechemistry, depleted asthenosphere mantle
