摘要
目标勘查区出露矿化类型为矽卡岩型矿化,矽卡岩型矿床中常含有能引起明显磁性异常的磁铁矿。为了在区内有效地指导探矿工作,我们使用HC-95a手持式氦（He^4）光泵磁力仪,结合高精度GPS测量,开展了地面高精度磁测工作。测区共进行17条测线,每条测线长700m,在区内西部圈定出两个明显高磁异常体（A,B）。A异常延长290m,宽50-200m;B异常延长300m,宽100-150m,均具有一定规模。两个高磁物探异常可能为矿化体引起,给下一步探矿工作指明了方向。
The mineralized type outcropped in the target area is skarn type. The magnetites which can cause obvious magnetic anomaly are often found in skarnic deposit. In order to instruct the prospecting work effectively in the target area. We have mainly used HC-95a ground helium optically-pumped magnetometer combined with high precise GPS survey to the prospecting for buried ore-bodies. 17 survey lines which are 700 meters long have been finished in mine holdings. In the end, 2 magnetic anomalies （A, B） have been discovered in the western part. Anomaly A is 290 meters long and 50 to 200 meters wide, and anomaly B is 300 meters long and 100-150 meters wide. Both of them have certain scale. Two high magnetism physical prospecting anomalies were possibly caused by the mineralized bodies. This indicated a direction for the next step prospecting world.
