Abstract: The method of quantitative interpretation is applied in analysis of the C 6 magnetic anomaly in Daban gold field to find out the cause of the anomaly.It is possible to understand the occurrence (shape,attitude and depth) of the anomalous bodies by quantitative interpretation,and then distinguish ore-caused anomaly from non-ore-caused anomaly,under specified conditions,on the basis of characteristic comparison of physical fields.An assessment is made on several easy and quick methods of quantitative interpretation that is suitable for high magnetic anomalies.By comparing the practical effects,it is proved that the triangle system interpretation is a simple,functional and worth to be popularized method.
