Zusammenfassung:Ⅰ. GEOLOGICAL SETTINGThe Bainaimiao Group outcrops in south-central part of Inner Mongolia (Fig. 1). It has been noted that the Ondor Sum ophiolite suite, mixture accumulation and Bainaimiao island arc volcano-sedimentary sequences as well-as Fe, Cu, Mo and Au ore deposits or prospects were developed in this area. There are some arguments on the mutual relation, tectonic
