Summary:Layering in the Skaergaard intrusion was produced by magmatic flow, by variations in the rates of nucleation and crystallization, and by compaction. Modal variations were caused by shifts of cotectic proportions. Oscillatory nucleation produced fine-scale cyclic layers but was less important than solution and reprecipitation during slow cooling and Ostwald ripening. Evidence for compaction is given. Numerical simulations involve surface energy caused by grain size variations, textural dependence of solubility and pressure solution in causing layering. [B.E.L.]
