THE APPLICATION EFFECT OF PRECISION MAGNETIC SURVEY IN QEVLANTAGE AREA
摘要
Abstract
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. Tawenchah-an area in the middle of the Qimantage metallo- genic belt is a favorable area to find skarn type i-ron metallic ore. Large-scale 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.关键词
