%X The northern and southern margins of North China Craton are the important molybdenum metallogenic belts in China, and a lot of molybdenum deposits were discovered in these two belts in recent years, this indicate that these belts have a huge exploration potential. The Triassic molybdenum deposits catch geologist's eye. The Triassic molybdenum deposits distribute along the northern margin, southern margin and adjacent area of North China Craton. The molybdenum deposits are controlled by regional EW-, and NW-trending faults, and is associated with acid granites and carbonitite dykes in time and space. The molybdenum deposits are usually distributed in granite body, along the endo-or exo-contact zones of the ore-forming rock body, or nearby. The molybdenum deposits can be classified into two types: porphyry and vein type. The vein type deposits are divided into two subtypes: quartz vein and carbonitite vein type deposits. The geochronology data shows that the molybdenum deposits in the northern margin and southern margin of the North China Craton and adjacent area were formed in 248~220Ma, and 226~210Ma, respectively. The corresponding geodynamic background is the syn-collisional and post-collisional extension of the newly-amalgamated North China-Siberian plates during Indo-Chinese epoch, and syn-collisional setting of the amalgamated North China-Yangtze plates.
