Pattern formation during crystallization and the formation of fine-scale layering.
Fine-scale layering is characterized by the laminar segregation of mineral phases on a mm to cm scale. Where best developed, it is found in specific associations within the Stillwater Complex. In the Banded series, layer spacing is proportional to crystal grain size, with the best examples of fine-scale layering characterized by coarse rock textures and the development of secondary structures. Quantitative modeling can explain many of the features of fine- scale layering, and suggests that textural features of igneous layering in general can become better defined with time.-from Author
