Fluctuating temperatures under hydrothermal conditions produce new I/S and kaolinite mineral assemblages suggesting that there are multiple reaction series by which I/S clays may form. They may be independent of each other and coexist within the same rock. If several reaction series do exist, then all I/S minerals cannot belong to the same chemical solid solution.Read More
