摘要
广东梅县嵩溪Ａｇ（Ｓｂ）矿床，位于广东东北部、蕉梅凹陷区内，中生代寨岗上火山喷发沉积盆地的北部边缘外侧。本文在研究矿床特征的基础上，着重研究了矿床成因特征，并做了成矿模拟实验，提出了该矿床是一个火山喷流沉积－热液改造的大型Ａｇ（Ｓｂ）矿床。火山喷流沉积大约发生于１５４Ｍａ（相当于下侏罗统），热液改造发生在上侏罗统大规模火山活动时期，是一个具有重要经济价值和理论意义的低温Ａｇ矿床。
Based on the geological characteristics of shongxi silver (Antimony) deposit,this paper emphatically studies the genesis characteristics and carries out the metallogenic simulated tests. The results show it's a large type of silver (Antimony) deposit derived from volcanic eruption sediment hydrothermal reworking.The volcanic eruption sediment takes place about 154 Ma (correspond to low jurasic) and The hydrothermal reworking occures during the large scale volcanic activity in the early jurassic. The Shongxi silver (Antimony) deposit is a important low temperature silver deposit with commercial value and theoretical significance
