Metallogenic Target Area of Shuicheng-Aijiaping Area in Guizhou is Delineated as the by 1∶50,000 Magnetic Abnormality

It did data process to the 1∶50,000 high-accuracy magnetic abnormality original information,by reduction and continuation,it calculated the height abnormality of different upward continuations.It analyzed and contract all the information,combine with geological,physical and chemical prospecting information,did character distribution to the magnetic abnormality contact.According to the metallogenic regulation and distribution rule of the lead-zinc deposit in Baimadong(in)-Shanshulin(out) and the abnormal lead-zinc,cooper and manganese deposit in this area,it delineated 7 a6bnormality target areas,19 big scale shallow partial magnetic abnormalities,all of them have some prospecting significance.It also infers that that may be caused by magnetic abnormality of rock mass and deposit.It should be the beneficial position of ore occurrence on the rock mass,rock wall contact and interlayer cracked belt.
