Abstract

Mawu gold deposit located in eastern part of Min-Li gold metallogenic belt，approximately 5~7 km away from the Zhongchuan rock，is a medium-sized micro-disseminated gold deposit found in recently years.In this study，through analyzing and systemizing great amount of raw materials obtained during the process of geological exploration，we summarized the deposit geology，physical and chemical characteristics as well.The main orebodies occurred in limestone and phyllite of Hejiadian Group at Devonian with the NWW trending，and the secondary fracture with the NWW trending was the main ore-controlling factors.Meanwhile，the hydrothermal alteration presented primarily for the pyritization，sericitization，silicification and carbonatization.Output of the ore was mainly influenced by three factors，lithology，structure and magmatic rock.Compared with wall rock，it displayed high polarization characteristics of low resistance.Combination feature of the Au element mainly exhibited appearance of Au，As and Sb.On this basis，the seven and eight vein in northern mine were believed to be a large potential in terms of body extended or extension after analysis.Additionally，there was parallel vein body （blind ore body） located at upper and lower plate of the known veins，which demonstrated that better mining ore prospects in northern part of the mine.
