Fig.1 Photographs of “Colorimetric” Result in 1∶50,000 Mine Survey Area of a Carlin-type Gold Mine in the Southwest of Guizhou province Note: No.1~25 is the sample to be tested, No.26~30 is the known standard sample(The contents of samples 26,27,28 and 29 are 0,20×10-9,50×10-9 and 80×10-9). When TMK is added, No. 11, 12, 15, 20, 21 and 24 begin to turn red. The higher the concentration of red, the higher the corresponding gold content.
