摘要
秦岭造山带及邻区华北南缘、扬子西北缘地区中晚元古宙时期存在一个由两个三联点构成的复合"三叉"裂谷系。该复合"三叉"裂谷系演化过程中有关的成矿作用可划分出四个具有一定成矿远景和战略勘探意义的大型金及多金属成矿带。
<Abstrcat>There is a composite 'triple forks' rift system ,which might consist of a triple junction of plates, in Qinling orogenic belt and its adjacent areas, including southern margin of North China plate and northwest margin of Yangtze plate. Mineralizing process during the evolution period of the 'triple forks'composite rift system can be divided to four large mineralizing zones of gold and multimetals minerals, with certain oreforming perspectives and strategic prospecting significance.
