Because it truly is incredibly tough to quantify Fe sulfide species with QemSCAN, petrography analysis was performed applying a transmitted and reflective light microscope on each ore forms. According to the evaluation of thin sections of Ore B, 1.five of Azvudine Description pyrite particles have been defined as framboidal having a size range of 0.01 mm. The marcasite particles had been observed as alteration and weathering minerals in an quantity of 2 , having a size range up to 0.3 mm. In some fragments, the pyrite crystals have been immersed within a second generation of pyrite. In other fragments, the pyrite was intergrown with sphalerite (Figure 3a), and the two minerals formed crus-Minerals 2021, 11, x FOR PEER Evaluation Minerals 2021, 11, 1218 Minerals 2021, 11, x FOR PEER REVIEW6 6 of 13 of 12 6 ofOre A/-20 + 10 Ore A/-20 + ten Ore B/+38 Ore B/+38 Ore B/-38 + 20 Ore B/-38 + 20 Ore B/-20 + 10 Ore B/-20 + 1081.74 81.74 77.01 77.01 51.09 51.09 44.39 44.tiform intergrowths.
