| 摘 要： | 寿宁大安银金矿主要产于晚侏罗世陆相沉积－火山喷发碎屑岩系中。矿体呈脉状、囊状等，受次级断裂构造控制，成矿在时空上与中生代中酸性火山、岩浆活动密切相关。根据矿石结构、构造、贮存状态以及围岩蚀变等特征，初步认为该矿床属于低温浅成火山热液脉状型。

| Abstract: | The Daan silver-gold ores mainly exist in the Late Jurassic terrestrial deposit-volcanic clastic sequence.The orebodies act like the veiny and cryptomere,which is controlled by secondary faulted structures.The ore-forming process has a close relation with Mesozoic intermediate and acid volcanic-magmatic activity in space time.Based on the characteristics of the ore textures and structures,the storage conditions and the wall-rock alteration,it is considered that the mineral deposit belongs to the deposit of the low temperature hydrothermal volcanic hydrothermal vein type. |
