This paper investigates the petrogenesis of the Cretaceous Mo-bearing granites in West Dabie orogenic belt.Utilizing the rock geological chemistry of these granites,the formation condition of the Mo deposits in West Dabie orogen is discussed,which is significant to recognize the geochemical dynamics background of West Dabie Mo metallogenic belt.Similar to the Cretaceous granites in East Dabie orogen,the magmatisms of Mo-bearing granites in West Dabie orogen could be divided into two stages.The early stage w...

0引言大别造山带是三叠纪华南陆块俯冲进入华北陆块之下形成的大陆碰撞型造山带(从柏林,1996;Liet al.,1999;郑永飞,2008).在早白垩世,可能受太平洋板块后撤作用的影响,造山带由挤压转换为伸展环境,热地幔物质上涌,加厚造山带被活化,发生了拉张垮塌并形成大量碰撞后岩浆岩(Wu e
