All the events recorded here occurred on the fringes of Gondwana. Here are observed mafic to intermediate metavolcanic rocks that are intruded by a biotite porphyry granodiorite. The contact with the granodiorite is gently dipping and near the water level in McClure Creek. The granodiorite is characterized by biotite clots that define a crude lineation and have dimensions approximately 2 cm x 1 cm x 2 mm. The granodiorite has a strong, almost gneissic fabric that parallels that in the mafic metavolcanic rock.
Foliations strike northerly to north and slightly west.
This is typical for rocks of the Carolina terrane in this area. The thin foliation or cleavage observed mesoscopically on weathered rock surfaces is also typical. In thin section or on some fresh surfaces in hand specimen, it may be seen that the mafic metavolcanic rocks have been completely recrystallized with the growth of relatively coarse, idioblastic amphiboles, and fine-grained, equant, polygonal grains making up the felsic phases. The origin of this recrystallization is obscure. Thus at least in these two areas, mafic metavolcanic rocks predate ca.
