Benkubi Concealed Magnetite Deposit Sounding by CCM-4 Magnetometer in Cambodia

By surface high- precision magnetic survey,magnetite is explored in the target area where large Quaternary system covered. The up and down continuation magnetic anomaly magnetic survey data of different height are calculated,according to the magnetic anomaly distribution features,magnetic parameter physical property and geologic condition,8 magnetic anomaly in this area are determined. When the value is more than500 n T,it's inferred it caused by magnetic anomaly. According to the normal magnetic distribution,some drills are arranged to test in the C1 normal magnetic anomaly area and other normal magnetic anomaly area.The magnetite was not found only in few drilling holes,the successful example is gotten which exploration by surface magnetic method,affords experience for other area with the same geologic background.
