“…The In-bearing sphalerite contains chalcopyrite in solid solution (Figure 6a,b, and Figure 8d), which is similar to observation of other In deposits [14]. Chalcopyrite is a common and In-enriched mineral in In-bearing deposits [13,47]. The EPMA data shows that the chalcopyrite in the type-I orebodies contains <0.02-0.40 wt % In.…”

“…Because the In-Lα (λ = 3.772Å) line experienced interference from the Sn-Lη line (λ = 3.789 Å) [13,53,54], and the Ga-Lα (λ = 11.292 Å) line experienced interference from the In-Lα (λ = 11.316 Å) line [13], 22 ppm In per 1 wt % Sn in stannite, and 500 ppm Ga per 1 wt % In in sphalerite were added to correct for this interference (as per the practice of Ref. [13]).…”

“…The In content of the sphalerite from the Chashan deposit is relatively low, and the In content of the chalcopyrite is also low. Stannite, a secondary mineral in the Sn-Pb-Zn deposits, consistently contains a small amount of In [4,13,24]. The type-I and type-II orebodies contain trace stannite.…”

“…Major In deposits or mineralization regions have been identified throughout the world, such as Mount Pleasant in Canada [6][7][8], southwestern Bolivia [4,9], southern Finland and adjacent areas [10][11][12], southwestern England [13], the eastern Erzgebirge in Germany [14], the Iberian Pyrite Belt [15,16], Japanese Arc [5,17], the Southern Dahinggang Mountains in northern China [18,19], and southern China [20][21][22][23][24]. Two types of primary, industrial In-bearing deposits have been identified: (1) volcanic-hosted massive sulfide deposits, e.g., Kidd Creek in Canada and Neves Corvo in The Xianghualing Orefield is a typical Sn-ploymetallic orefield in southern Hunan.…”

Abstract:Although numerous W-Sn-Pb-Zn polymetallic deposits are located in southern Hunan, and In-bearing deposits are related to W-Sn-Pb-Zn polymetallic deposits, Indium mineralization in southern Hunan is poorly studied. In order to investigate the In mineralization of the Xianghualing orefield, which is a typical orefield in southern Hunan, ore bulk chemistry, microscopic observation, and electron-probe microanalysis of vein-type (type-I) and porphyry-type (type-II) Sn-Pb-Zn orebodies were studied. The In contents of the type-I orebodies varies from 0.79 to 1680 ppm (avg. 217 ppm, n = 29), and that of the type-II orebodies varies from 10 to 150 ppm (avg. 64 ppm, n = 10). Although chalcopyrite and stannite contain trace amounts of In, sphalerite is the most important In-rich mineral in the orefield. Sphalerite in type-I orebodies contains from <0.02 to 21.96 wt % In, and in type-II orebodies contains from <0.02 to 0.39 wt % In. Indium-rich chemical-zoned sphalerite contains 7 to 8 wt % In in its core and up to 21.96 wt % In in its rim. This sphalerite may be the highest In-bearing variety in Southern China. The Cd contents of the In-rich sphalerite ranges from 0.35 to 0.45 wt %, which places it in the the "Indium window" of the Cu-In-S phases. The geological and structural features of the Xianghualing orefield indicate that the In mineralization of the two types of In-bearing Sn-Pb-Zn orebodies is related to the volatile-rich, In-rich, A-type granites, and is controlled by the normal faults of magmatic-diapiric activity extensional features.

“…Indium and Cd are strongly correlated with Zn, indicating In and Cd are hosted mainly by sphalerite. Some samples (e.g., L1) with high In/Zn ratios and Cu concentrations may indicate that chalcopyrite hosts In, similar to the Yejiwei deposit and In-rich deposits in SW England [55,56]. The second group contains the elements Cu, Bi, Sn, and Pb, of which Cu and Bi are strongly correlated.…”

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magnetite-pyrite, and magnetite. The results show that In is richest in the sphalerite-pyrite ores, with concentrations of 28.9-203.0 ppm (average 122.8 ppm) and 1000 In/Zn values of 2.7-10.9 (average 7.0). Other ore types in the Qibaoshan deposit are In poor, whereas all are Sn poor (10 to 150 ppm), with most samples having Sn concentrations of ≤70 ppm. Indium is mainly hosted by sphalerite, as inferred from the strong correlation between In and Zn, and weak correlation between In and Sn. Mineral paragenetic relationships indicate sphalerite formed from late quartz-sulfide stage of mineralization processes. Indium in the Qibaoshan deposit is richer in vein-type orebodies than in lenticular-type orebodies occurring at contact zones between carbonate and quartz porphyry, or in carbonate xenoliths. Igneous intrusions that were Sn poor and emplaced at shallow depths formed the In-rich orebodies of the Qibaoshan deposit.
