| Abstract: | The sandstone copper of Xiang Mountain formed in the Dl2 of upper Devonian as a layered rock.Its minerals mainly are Malachite,Azurite,Chalcocite and Chalcopyrites,accompanying by some silver.The mineralizing position is in the side zone of an inland basin,where the geochemical environment is becoming from a strong oxidizing milieu to a reducing milieu.Through the discussion and researches on the geological features of the mineralizing environment of the sandstone copper,the ore-hunting indicators were put ... |
