| 摘 要： | 皇城山银矿床,是大别山北麓首次在中生代火山岩中发现的一个浅、易、富中型矿床。中生代白垩纪火山活动在时间、空间、物质等方面对于矿床的形成起着支配和导向的活动,成矿流体来自岩浆岩和雨水,是陆相火山作用形成的中(低)温热液充填单一型银矿床。本文在前人工作基础上对矿床的成因做出了新的解释。

| Abstract: | The Huangchengshan Ag deposit in the north foot of the Dabie Mtn. is confined to the Cretaceous volcanic rock. The mesothermal and epithermal ore-formation is in close relationship with continental volcanism. Ore fluids were derived from magmatic water and meteoric water. This paper re-explains the ore genesis based on previous data. |
