More model informationThis roadcutting in the northern part of the Tia Metamorphic Complex in the southern New England Orogen exposes a migmatite that records peak metamorphic conditions. Temperatures here reached ~550°C - conditions at which the rock began melting. St this temperature muscovite begins to break down, liberating water which enhances melting reactions. The melt pods (leucosomes) are labelled in the model.
Although three phases of folding are evident in the outcrop, they are difficult to discern in this model. Folding can be viewed in other models here, here and here. The cutting is ~2 metres high.
