Abstract
This article explores the rock characteristics of the ore bearing rock mass in the Hongling tungsten mine,and believes that the rock mass is mainly divided into three stages,rather than the four stages previously believed.The mineralization age of the Hongling tungsten deposit is consistent with the magmatic activity age of the third stage of Yanshan.The Hongling tungsten deposit is closely related to granite intrusions in space,and the ore-forming materials and fluids both come from magmatic rocks,indicating the close relationship between the formation of the Hongling tungsten deposit and the late Yanshan granite.It is controlled by the background of granite formation during this period,which also occurred in the extensional tectonic system of the Middle and Late Jurassic region.关键词
