| Abstract: |
| The Daye iron ore deposits is one of national large-scale mines,which is at the resources crisis stage at present.Through studying on contact zone shape,change of Fe and Cu grade,as well as the high accuracy magnetometer survey,thinks the zone to conform to the result of the magnetometer survey is the advantageous mineral zone.The line graphs of Fe and Cu grade show that magnetite changes into pyrite from the west to east of contact zone,and obtains success in practice. |
