Polymetallic survey and metallogenic condition analysis in Xinzhuang area of South Shandong
In the progress to carry out the 1∶50000 regional mineral geological survey project of Xinzhuang ampuli-tude in Shandong Province,through collection and analysis of the relevant geological achievements in the past,with the methods of remote sensing geological survey,geophysical prospecting methods(including gravity survey,magnet-ic survey,gravity and magnetic profile,γ-spectrum profile),heavy sand survey,sampling and testing analysis,com-prehensive mineral resources inspection,and comprehensive investigation and research,three remote sensing anoma-lies and three prospecting targets are delineated,and 11 local gravity anomalies are delineated,including 5 high gravi-ty anomalies and 6 low gravity anomalies,a number of 946 grains of diamond indicator minerals are selected from 9 lamprophyre dikes in the heavy sand survey.It narrows the area for diamond prospecting and provides a lot of dia-mond prospecting information.This mineral resources survey work delineates one typical metallogenic prediction are-a,in where gold metal resources of 3101 kg and total rare earth oxide amount of 50212 t are estimated,two metallo-genic prospective areas,four prospecting prediction areas and one prospecting target area.One copper-zinc-gold ore occurrence,one copper ore spot,one copper and rare earth ore spot and one REE ore spot are also found as well.The metallogenic geological condition is analyzed and the prospecting potential is evaluated.
