摘要
Tepogeritu ultrabasic rock bodies are located in the Buyant uplift belt, central Inner Mongolia , in which faults, geological structures, magmatic rocks and metallogenic conditions develop very well. The major element contents of the rock bodies are SiO2 12.95%～40.18%, Na2O+K2O 0.086%～0.734%, A/CNK 0.019%～0.076%, MgO 15.13%～25.32%, m/f 2.5～6.3. The microelement analysis data show that contents of Ni、Co and Cr are very high. The REE distribution patterns are flat to slightly rightist, indicating a weak enrichment. Based on the study of the systematic geology, geochemistry, geophysics and ore potentiality, it is proposed that the ultramafic rock bodies belong to iron-ultrabasic type containing rich Cu-Ni sulfide deposits /minerals. The ore deposit with good ore potentiality has been found in the ultrabasic rock bodies. So the authors suggested that there is great prospection in this rock bodies.
