摘　　要：本文探讨了红岭钨矿含矿岩体岩石特征,认为岩体主要分为三个阶段,而不是前人认为的四个阶段。红岭钨矿成矿作用年龄与燕山三期岩浆活动年龄一致,红岭钨矿床在空间上与花岗岩类侵入体产出密切,成矿物质、成矿流体又均来自于岩浆岩,指示了红岭钨矿的形成与燕山晚期花岗岩的密切性,受控于该时期花岗岩形成的大背景,即也发生在中晚侏罗世区域伸展构造体制中。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.
