| 摘 要： | 以钾、钠含量变化为主要指标获取祁漫塔格地区各个地史时期花岗岩类的成因类型.结果表明,区内构造岩浆作用在时间上具有明显的阶段性,加里东中晚期是本区第一次侵入岩浆作用的高峰期,印支中晚期为本区花岗岩浆作用的鼎盛时期,加里东中晚期和印支中晚期也是区内两次区域成矿作用的大爆发期.岩体分布具有明显的方向性.主要由北东向和北西向两...

| Abstract: | The genetic types of granite rocks of various geological periods in the Qimantage region were discriminated by the contents of K and Na. The middle to late Caledonian and middle to late Indosinian are two phases of extensive granitic intrusions,and also massive mineralization in the region. The granitoid rocks occur mainly along NE and NW structural magmatic belts,moreover since Caledonian,the two belts differ in distribution,genetic type,and scale. The alkali metasomatism and mineralization of the two tect... |
