| 摘 要： | 西藏仁布县仁布超基性岩体的高精度磁测综合平面图显示，以△T=2000nT组成的等值线闭合圈清晰地反映出超基性岩体的范围，高精度磁测异常与超基性岩体吻合。该区物探推断成果已经得到工程验证，取得良好的效果，首期已采掘铬铁矿近10000t。

| Abstract: | The integrated plane of high-precision magnetic survey on Renbu ultrabasic rocks shows clearly enclosed AT= 2 000 nT contours that is coincided with the distribution of ultra-basic rocks. The geophysical inference for the working area has been verified by the exploration engineerings and the first excavation harvest 5,000 tons of chromite ore. |
