摘要
In this paper, it tried to take lamproite outcrop in maping area and its correlative spectral response value of 1∶200 000 regional gravity and magnetic abnormality as the clue,the distribution of Augitic Placer Abnormality, diamond placer deposit, chrome-spinel which is the target mineral of diamond, limited material and part gravity and magnetic abnormality points as the basis, a big gravity and magnetic abnormal in Taijiang-Jianhe-Liping area is studied and determined. It’s suggested the diamond exploration should be done with the center of gravity and magnetic abnormal in Jianhe, the G3 geophysical prospecting gravity and magnetic in Nanjia-Pingqiu area as the earlier exploration target.
