英文摘要: Abstract(#br)A recently recognized molybdenum (Mo) metallogenic belt is present within and adjacent to the northern part of the North China Craton (NCC). More than 20 Mo deposits are present in the belt, including the Sadaigoumen and Dacaoping porphyry deposits located in the Fengning region of the northern part of Hebei Province. The Sadaigoumen deposit has a Re–Os molybdenite weighted mean age of 236.5±2.2Ma (MSWD=1.4, n =6), which is more reliable than existing dates and is interpreted as the precise age for formation of the deposit. The Dacaoping Mo deposit is about 100million years younger, with a Re–Os molybdenite isochron age of...
