APPLICATION OF ELECTRICAL CONDUCTIBLE DEGREE AND INFRARED SPECTRUM IN PROSPECTING AND EVALUATING OF GOLD DEPOSITS

Electric conductivity is a relative ruler to the conductance of ore-forming solutions. The value of electric conductivity can directly reflect the concentration value of ore- forming solutions. Quartz is an important gangue, as well as a main carrier of gold-hosting mineral in the Ciweigou and Sandaowanzi gold deposits. Quartz is studied using an electrical conductible degree of ore-bearing fluids and infrared spectrum. The results show that electrical conductible degree and D_(CO_2) detected by infrared spectrum has a positive relation to Au content in quartz. Electrical conductible degree over (34.3)μS and D_(CO_2) large than 0.2 indicate intense gold mineralization. This information of quartz is significant to the prospecting and evaluation of gold deposits in the area of Mesozoic continental volcanic rocks.
