摘要
Mawu gold ore area is located at northwest outer contact of Zhongchuan intrusion in the west Min-Li ore belt.Gold ore is mainly controlled by Mawu anticline.In the gold ore area 7 auriferous quartz veins are discovered.Auriferous quaetz vein 1,7 and 8 in the the north ore zone are controlled by workings in higher degree and the gold resource volume is determined.Auriferous quartz vein 2,3 and 4 in the south ore zone are in big thickness with relatively lower gold grade and the south zone is generally considered more potential.Study on geological and metallogenic event sequence and the metallogenic mechanism shows that the north zone in the north limb of Mawu anticline is more favorable in ore material source,ore-hosting structure etc.than the south zone in the south limb and the exploration should be focused on the north zone.
