China University of Geosciences, Beijing 100083 ) Abstract : The Huachanggou gold deposit , located in Shanxi-Gansu-Sichuan “ Gold Triangle ” mineralization area, occurs in the Sanhekou G roup of middle-lower Devonian( D 1-2 sh). The gold mineralization zone is strictly controlled by strata, ductile shear zone and alteration zone. The major types of gold ore are altered spilite and altered carbonate rock. It’s important for prospecting to study its unique ore-forming geological characteristics and ore-controlling factors, and to establish the metallogenic model of the area. Key words : gold deposit; geological characteristics; ductile shear zone; ore-controlling factors; prospecting direction 铧厂沟金矿床位于陕西省略阳县郭镇, 西与甘肃省康县毗邻。该矿床的区域构造位置位于扬子地块西北缘拉张增生带与秦岭造山带南部碰撞边缘之间的“勉(县)略(阳)宁(强) 三角地带”, 区域构造线呈近东西向展布。经多年的勘查工作,已达中型规模。 1区域地质背景铧厂沟金矿区处于加里东褶皱带和华力西褶皱带的结合部位, 构造活动强烈, 尤其是中、新元古代和华力西期地壳拉张, 火山喷发, 以及稍后的韧性剪切活动对本区矿化富集有一定作用。北侧的康-略- 勉深大断裂作为一级导矿构造提供部分矿质来源的可能性不容忽
