中文摘要	在移动沙丘地区开展地质勘查工作,物探方法的选择非常重要。高精度磁测是寻找铁多金属矿首选物探技术方法,目前在青海省祁漫塔格地区的地质找矿工作中发挥了非常重要的作用。祁漫塔格成矿带中部的它温查汉地区是寻找矽卡岩型铁多金属矿的有利地区,但是该区分布有大面积的移动沙丘,高数米至数十米地层均被沙漠覆盖,地表地质工作难以发挥作用。而大比例尺地面高精度磁测和钻探是一种行之有效的方法组合,在这一勘查方法组合中,大比例尺高精度磁测异常的解释推断非常关键,这里通过实例说明1∶10 000高精度磁测在沙漠覆盖区的找矿效果良好。
英文摘要	The selection of geophysical methods is very important when geological exploration work is carried out in the areas of traveling dunes. The high precision magnetic surveying is the preferred geophysical technique to find the iron metallic ore. It played a very important: role in geological prospecting work in Qimantage area. Tawenchahan area in the middle of the Qimantage metallogenic belt is a favorable area to find skarn type iron metallic ore. Largescale ground high precision magnetic surveying and drilling is an effective combination in this area. Due to a large area of traveling dunes are distributed in the region with few meters to dozens of meters high and the strata are covered by desert, so the surface geological work is difficult to play a role. Inferred interpretation of the large precision magnetic anomaly is critical in this composition of the exploration method. This article is to illustrate the prospecting effect of 1: 10 000 precision magnetic survey in desert areas by examples.
