(a) Field view of the main exposure in part B of the outcrop (location in Fig. 4), showing the presence of a ∼70 cm thick layer of leucocratic gneiss within mesocratic gneisses. (b–d) Closer views illustrating the presence of syn-kinematic leucosomes within the layer of leucocratic gneiss. (e) Closer view of the mesocratic gneisses in the vicinity of the pegmatoid vein sampled as P04-44, showing that thin syn-kinematic leucosomes are also present in these gneisses. (f) Photomicrograph of sample P04-44 in cross-polarized light (see the text for description).
