摘要
The main ore body of Sanshandao gold deposit is characterized by fractured altered rock type mineralization.In the deposit large gold-bearing quartz veins were discovered in recent years.Large gold-bearing quartz veins are similar to gold-bearing quartz veins in exquisite type gold deposit in terms of geological features,but fractured altered rock type mineralization in the same deposit is different.Filling is the major feature of large gold-bearing quartz veins,while metasomatosis is that of fractured altered rock type mineralization.
