| 摘 要： | 秦岭横亘中国大陆中部，东西绵延1300km，地跨豫、鄂、皖、陕、甘、青、川七省，面积约400000km2，它是我国著名的"中部多金属成矿带".金银矿产为重要的优势资源，矿床星罗棋布.迄今为止，已探明金矿床145处，其中砂金矿床44处，岩金矿床101处；银矿床24处.该区金、银矿床成矿类型繁多，具有得天独厚的聚矿条件，其中小秦岭享有"第二金库"的美称.遐迩闻名的"陕甘川金三角"地区的成矿受巨型帚状构造控制，可与全球诸多巨型-超巨型金矿之聚矿条件媲美.本区金、银矿产成矿规律明显，具有极其理想的成矿条件，是进一步查勘巨型-超巨型金矿的最佳地区

| Abstract: | Qinling locates in the central part of China continent,stretching 1300 km from east to west It's well known as“central polymetal metallogenic zone”in China Gold and silver are superiority natural resources Up to now,we have found 145 gold deposits(44 placer gold and 101 rock gold deposits)and 24 silver deposits There are many metallogenic types of gold and silver deposits in this area It possess better ore forming conditions The mineralization for the famous“Shaanxi Gansu Sichuan gold triangle”was controlled by megabrush structure,can be comparable with many mega ultromega gold deposits all over the world The metallogenic regular of gold and silver deposit is obvious This area possess very ideal ore forming condition,and is the best place to explore mega ultromega gold deposit further |
