GEOLOGICAL CHARACTERISTICS AND PROSPECTING TARGETS OF THE NORTHWEST SECTION OF THE AILAOSHAN GOLD BELT,YUNNAN
Ore bodies of the three gold mineralization alteration zones in the Niujie area,northwesternAilaoshan gold belt,Yunnan,are layered in thestrutuaral fracture zone of the Lower Paleozoic sericite quartz microcrystalline schist.They are generally distributed in the NW-SE direction,inclined toNE,with a thickness of 0.69-4.11m and an Au grade of 1.10ω×10-6～4.20ω×10-6.The deposit is of low metamorphic clastic rock type.The structural fracture zones,the ore-rich layers,the intrusive rock masses and the silicification-limonite(pyrite)mineralization zones with both physical and geochemical anomalies are the favorable areas for exploring gold deposits.Three prospecting target areas have been delineated.
