摘要
探测深部有色金属矿产资源是中国矿产勘查的重要任务,地球物理方法是完成这一任务的重要手段。深部有色金属矿床具有埋藏深、周边干扰大和信号显示弱等特点,勘查难度大,对勘探技术要求较高。在简要概述地球物理勘探方法的特点和前人勘探技术路线的基础上,选取应用不同地球物理勘探方法探测深部有色金属矿床的典型实例进行了介绍和总结,从而指出了对于深部有色金属矿床的地球物理勘探应该在深入了解研究区成矿规律的基础上,合理地采用2种或多种先进的地球物理探测手段对研究区进行综合探测,并强调了对数据进行综合处理与解释的必要性。
Detecting deep nonferrous metal resources is an important task of mineral exploration in China. Geophysical methods are important means to accomplish this task. Deep nonferrous metal deposits are characterized by deep burial,large disturbance of surrounding area and weak signal. The exploration is difficult and requires advanced exploration technology. Based on a brief review of the characteristics of geophysical prospecting methods and the predecessors' prospecting technical routes,some typical examples of deep nonferrous metal deposits using different geophysical exploration techniques and methods are introduced and summarized. It is pointed out that for the geophysical exploration of deep nonferrous metal deposits,two or more advanced geophysical exploration methods should be reasonably used to explore the study area comprehensively on the basis of deep understanding of the metallogenic law of the study area,and the necessity of comprehensive data processing and interpretation are emphasized.
