高磁三维反演在格尔木市那陵郭勒河西铁多金属矿区的应用

青海省格尔木市那陵郭勒河西铁多金属矿区地处柴达木盆地西南缘半干旱荒漠化草原区,第四纪分布广,厚度大,高精度磁测是本区主要的找矿方法之一。磁法勘探中对磁异常的定量解释主要有二维反演和三维反演。三维反演是基于计算机技术的发展而被采用的一种定量解释方法。本文利用三维反演方法对本地区磁测资料进行解释及资料分析,说明三维反演在本地区磁测资料解释及指导找矿方面有很大的优势。

Application of three -dimensional inversion of high magneticin western part of Nalingguole River iron polymentallic mining area in Golmud city

The western part of Nalingguole River iron polymetallic mine field is in Golmud city in Qinghai Province located in the southwest edge of the Qaidam Basin which belongs to the semi - arid desert steppe zone. Quaternary is widely distributed with large thickness in the field, so highly precise magnetic survey is one of the primary prospecting method. Main quantitative interpretation of magnetic exploration on the magnetic anomaly includes two - dimensional and three - dimensional inversion. Three -dimensional inversion is one of the quantitative interpretation adopted because of the development of computer technology. This paper intends to illustrate the great superiority of three - dimensional inversion in explaining magnetic survey data and directing prospecting, which is based on using three - dimensional inversion to explain and analyse magnetic survey data of the field.
