Infrared (IR) studies of fluid inclusions in opaque minerals provide direct insights into the ore-forming fluids. However, the challenge posed by the "warming effect" of IR light during microthermometry remains unresolved. Here we address this problem and show that the deviation in temperature of phase changes within fluid inclusions caused …Web
Indium mainly occurs as solid solution in sphalerite. Other minerals such as stannite and chalcopyrite (Ia) exhibit relatively elevated In concentration (average > 202 ppm).Web
The main carrier of indium is sphalerite (Table 1, Fig. 3), the average content of which in the ore is 5.5%. Other minerals with high indium content (stannoidite, mawsonite) do not provide essential influence on the indium balance in ores because of an extremely small abundance (<0.01%). This is also true for the indium mineral roquesite.Web
