///Located in Liangcheng uplift of Inner Mongolian massif(Axis)within North China Craton, the newly discovered Dasuji and Caosiyao deposits are large-size and superlarge Mo deposits in central Inner Mongolian, respectively. Preliminary studies show that both the Dasuji and Caosiyao deposits were formed during the Mesozoic Indosinian and Yanshanian extensional tectonic movements that resulted in the intensive igneous activities. The genetic model and mineral exploration criteria of the Dasuji and Caosiyao deposits can also be used as useful tools during the comprehensive evaluation of concealed Mo deposits in Inner Mongolian massif of the North China Craton.oft-com:office:office" />
