Regolith deposits

Fig. 1. Dissolved Mo distribution at the Baxter deposit in Western Australia has a much greater and consistent anomaly compared to dissolved Au (not shown). The results are superimposed on maximum Au contents in the regolith to show the extent of mineralisation.

Elemental distribution patterns in regoliths partly result from long-term geochemical changes occurring in surficial deposits and soil profiles. Accordingly, these patterns were used to calculate weathering rates (Olsson and Melkerud,...

The soils on Mt. Erebus were first described by Ugolini (1967). The rocks around the Main Crater of Mt. Erebus are coated with salts which also occur locally within the regolith. Keys (1980) and Keys and Williams (1981) identified the compounds listed in Table 16.3 which contain not only chlorine and fluorine, but also sulfate that forms by a reaction of sulfur dioxide gas with water vapor and oxygen of the atmosphere. In addition, the salts on the summit of Mt. Erebus contain aluminum, silicon, and iron (Keys and Williams 1981). Although some of the salt deposits in Eig. 16.22a and b are distinctly yellow, native sulfur is not present. Instead, the yellow deposits are probably composed of jarosite[(K,Na)(Ee,Al)(SO,),(OH)g]. 

Regolith The general term for fragmental, unconsolidated material that forms a cover over more coherent bedrock. May be either a residual or transported deposit.
