WebJan 1, 2012 · More than 80 years ago, Goldich (1938) suggested a stability series for the major primary minerals (Figure 1-3), based on the rationale that the higher temperature at which a mineral crystallized ... WebS. S. Goldich derived this series in 1938 after studying soil profiles and their parent rocks. Based on sample analysis from a series of weathered localities, Goldich determined that the weathering rate of minerals is controlled at least in part by the order in which they crystallize from a melt. This order meant that the minerals that ...
