Timing of weathering-induced alteration and manganese deposits in Western Australia: evidence from K/Ar and 40Ar/39Ar dating
Description
Under particular climatic conditions, tetravalent K-Mn oxides can be formed during terrestrial chemical weathering of Mn ores. In this study the results of K/Ar and 40Ar/ 39Ar dating of weathering-related K-Mn oxides (mainly cryptomelane (K,Ba)Mn 8O 16 ·
