| Abstract: | To reveal the weathering processes of gold-bearing carbonate rocks and their constraint on gold enrichment, this paper, taking the Shewushan lateritic gold deposit in Hubei Province as an example, presents a systematic study of elemental geochemistry and mineralogy. The results show that from the saprolite layer to its relatively upper mottle layer, the contents of FeO, MnO, organic carbon, REE, alkali metals, HSFE and a group of minerals including K-feldspar, plagioclase and pyrite have dramatically declin... |
