Figure 1. Distribution of Late Paleozoic Plutons in the Eastern Piedmont of the Southern Appalachians.<br />
Ruled pattern: Low grade metamorphic rocks, primarily <strong>Carolina</strong> slate belt. Large stippled pattern: Undeformed late Paleozoic plutons<br />
(including nos. 7 and 8). Small stippled pattern: Locally deformed late Paleozoic plutons (including no. 1). Black: Deformed late<br />
Paleozoic plutons (including nos. 2,3,4,5, and 6). Dashed line: Faults. NCF-Nutbush Creek Fault. Dotted line: Coastal Plain-Piedmont<br />
contact. KB-Kiokee belt. RB-Raleigh belt. Tr-Triassic basins. CB-Charlotte belt. KM-Kings Mountain belt. IP-Inner Piedmont.<br />
Information regarding numbered plutons is given in Table 1.<br />
belts are characterized by being fault-bounded and by being<br />
at higher metamorphic grade than adjacent areas.<br />
As the Kiokee belt passed into Georgia, the intensity of<br />
tectonic activity appears to decrease. The Sparta complex<br />
(Figure 1, no. 8) is undeformed. A biotite from this complex<br />
has a K-Ar age (Kulp and Eckelmann, 1961) which is nearly<br />
concordant with the Rb-Sr whole-rock isochron age suggesting<br />
that this granite was emplaced into relatively cold country<br />
rock and is post-metamorphic.<br />
Late Paleozoic plutons of the Raleigh belt are foliated<br />
only along the margin of the belt (Figure 1), possibly where<br />
they are adjacent to the Nutbush Creek fault. Since the character<br />
and extent of this fault zone is uncertain (J. M. Parker,<br />
III, 1977 pers. comm.) the exact nature of late Paleozoic<br />
deformation in this area must await more detailed mapping<br />
and structural analysis.<br />
