摘要
目的为加速矿区及其外围的找矿。方法利用航磁及磁重信息向上延拓所产生的不同高度重、磁二阶导数的解译和推断,划分岩体,同时运用综合信息成矿预测理论和方法。结果通过研究岩浆岩体的地质、地球物理场和地球化学场特征,对新疆富蕴县萨尔布拉克一带岩浆岩体进行了单元划分和金成矿有利度评价。新疆富蕴县萨尔布拉克一带岩浆岩体分为早期岩体和晚期岩体。结论金矿成矿主要与晚期岩体关系密切,晚期岩体不仅对Au而且对Cu,Ni也有一定的控制作用。
Aim To accelerate the prospecting of mining area and its outer-ring＇s. Methods make use of the interpretation and inferring from the second derivative of gravity and magnetic of different heights produced by upward extension of aeromagnetism and gravity information. Results The intrusion phases of rock bodies; apply the mineralization prediction theory and method from comprehensive information to divide the unit of the magmatic rocks in the Saar Bulake region in the Fuyun County of Xinjiang was devided and the advantageous degree of gold minerali- zation were estimated through studying the characteristics of geology, geophysical field and geochemical field of the magmatic rocks. The magmatic rocks in the Saar Bulake region in the Fuyun County of Xinjiang are divided into rock bodies of early and later phases. Conclusion The gold mineralization is closely related to the later rock body which not only controls the gold mineralization but also controls the mineralization of copper nickel.
