【摘要】 对物探资料综合研究的一般原则进行了论述。结合工作实践阐述了高精度磁测追索覆盖层下的含矿破碎带的有效性,列举了用重磁法圈定与成矿控矿有关的岩体和间接找矿的成功案例。强调直接找矿与间接找矿并举、重视对物探低缓异常和"剩余异常"的解释研究等观点,提出要重视钻探等验证后的再解释和井中物化探工作以及新技术、新方法在矿产检查中的应用与研究,最大程度地提高并扩大对成矿信息的获取能力,从而提高物化探的勘查能力和找矿效果。更多还原

【Abstract】 Based on the discussion about the general principles of geophysical data study and combined with practical work,this paper describes the effectiveness of ore-bearing fractured zone covered by highprecision magnetic measurement shows some successful cases of indirect prospecting and enumerates the rock related to ore-forming and ore-controlling,which delineated by gravity and magnetism method.Equal attention should be paid to the direct and indirect ore prospecting,and the viewpoint such as geophysical weak gentle anomaly and the ’residual anomaly’ interpretation should be taken into consideration.In addition,more attention should be paid to re-interpretation after drilling verification,to geophysical and geochemical well-logging operation,to application and research on new technologies,and to new methods about mineral examination.Moreover,it is necessary to improve and expand information acquisitioning ability to the greatest degree,thus promoting the capacity of geophysical and geochemical exploration and results.更多还原
