| 摘 要： | 对许窑沟金矿产出的地质背景，矿床特征，控矿因素及矿床成因等几方面作了系统的论述，提出了断裂，特别是韧性剪切带对成矿的主要控制作用；花岗岩与成矿有较大的时差，具有穿时，穿层的特点，它起着沟通深部与浅部的作用，并使深部的含Au流体沿断裂破碎带上升，沉淀而成矿。

| Abstract: | The geological background, deposit character, ore controlling factors and deposit genesis were discussed. The fault, especially ductile shear belt controlled the mineralization mainly. The age of the mineralization and the granite was different and had the character of diachroneity and rerticality. Granite connected depth with shallow and caused deep auriferous metallogenetic fluid through rifted fractured zone uplifting and precipitation. |
