Abstract：High resolution magnetic survey and borehole triple-component magnetometry are the effective magetic prospecting methods,especially much more significative for the exploration of banded iron formation (BIF)type iron deposits around cov-erage region.The Shanzhuang iron deposit,located in the covered regions of north of the Yellow River in Shandong Province, is a medium-to large-scale magnetite-quartzite type iron deposit.The deposit includes more than 20 iron bodies,which occur in the Shancaoyu Formation of the Neoproterozoic Taishan Group.The iron bodies dip to the southwest at 56°- 70°.Average grade is about 28% for the total iron,and 22% for the magnetic iron.Taking the prospecting of the Shanzhuang iron deposit as an example,it aims to introduce an integrated prospecting method for BIF iron deposits in covered regions.Based on regional geological and geophysical characteristics,such as aeromagnetic anomaly,a high-resolution magnetic survey and profile meas-urement in favorable prospecting places were carried out,and the best drilling spot is chosen.It is found in the study that the borehole triple-component magnetometry during drilling and right before ending of drilling should be paid special attention,which could not only help find blind ore bodies,but also indicate abnormity around the borehole.
