The initial metamorphism appears as a zone of coarsely crystalline hornfels
adjacent to the tonalite contact. Close to the contact, biotite forms large (1 mm)
sieve-textured porphyroblasts but in the outer hornfels it occurs as small (0.2 mm)

The color difference between the pelitic hornfels and calc- hornfels beds is
caused by the presence of much fine carbonaceous material in the pelitic
hornfels. Light-colored calc-hornfels layers generally have wavy contacts with the
contiguous ...
