| 摘 要： | 在综合信息矿产预测理论与方法指导下,通过地质、物探、化探资料综合信息解译工作,对阿尔泰成矿区大型、超大型矿床成矿规律进行了综合研究。绝大多数金、铜、铅（锌）矿床具有相同或相似的控矿因素,矿床我有共生或伴生的特点。它们处于：大地构造相对抬升的单元背景;不同大地构造单元相结合的部位;前寒武系变质岩系出露基底和隐伏基底及其边缘;泥盆纪火山岩或沉积岩组成的盆地边缘;中酸性继承性岩体及其接触带附近;重力场梯度带附近与重、磁资料推断相吻合的断裂构造及交汇处,以晚期重、磁构造为主;高、中、低温元素组合异常汇水盆地密集区。

| Abstract: | Under the guidance of the theories and methods of metallogenic prognosis by using synthetic information, authors made a synthetical study for giant ore deposits metallogenic regularities in Xinjiang Altai Metallogenic Provinces using interpretation of geology,geophysics and geochemistry. Most ore deposits of Au,Cu,Pb(Zn) have the same or similar ore-controlling factors.The ore-controlling factors are: they are in relatively pressure tectonic unit;integrated position on the various tectonic unit;Precambrian metamorphsite for outcropped and concealed basement or its edge;Devonian basin-margin that are consisted of sedimentary or volcanic rock;intermediate acidity inherited rock body or close to its contact zone;close to the gravitational field gradient zone;coincidence offset through magnetic method and gravity information tentatived and their convergence position;abnormal catchment concentration area of high,middle and low-temperature element composite anomaly. |
