520 3 a| The Sims pluton, a medium to coarse-grained calc-alkaline granitic stock, is intruded into low rank metamorphic rocks of the Eastern Carolina Slate Belt. The granite is non-porphyritic and shows no metamorphic foliation. Major and trace element analyses of fifteen samples indicate that the granite is peraluminous, with average molecular Al₂0₃/Na₂0 + K₂O + CaO = 1.57. SO₂, FeO, and TO₂ average 73.6, 1.78, and 0.3% respectively. Trace element distributions correlate well with those in other late Paleozoic granites of the southeastern Piedmont. The average Rb/Sr ratio is 0.60. The granite is composed of quartz, two feldspars, and minor biotite and chlorite. Locally it is hydrothermally altered. Epidote and calcite commonly coat joint surfaces and sericite and sulfide phases are abundant in altered zones. Rb-Sr whole rock age determination establishes the time of emplacement at 285 ± 2 my. Excellent correspondence of the whole rock and mineral isochrons indicates that there was no postemplacement metamorphism. The initial Sr⁸⁷ /Sr⁸⁶ ratio is 0.7044 ± 0.0005, suggesting an upper mantle or lower crustal origin for the granite magma. This age further supports 300 my as a time of major plutonio activity in the eastern portion of the southeastern Piedmont of the Appalachians.;

Summary	The Sims pluton, a medium to coarse-grained calc-alkaline granitic stock, is intruded into low rank metamorphic rocks of the Eastern Carolina Slate Belt. The granite is non-porphyritic and shows no metamorphic foliation. Major and trace element analyses of fifteen samples indicate that the granite is peraluminous, with average molecular Al₂0₃/Na₂0 + K₂O + CaO = 1.57. SO₂, FeO, and TO₂ average 73.6, 1.78, and 0.3% respectively. Trace element distributions correlate well with those in other late Paleozoic granites of the southeastern Piedmont. The average Rb/Sr ratio is 0.60. The granite is composed of quartz, two feldspars, and minor biotite and chlorite. Locally it is hydrothermally altered. Epidote and calcite commonly coat joint surfaces and sericite and sulfide phases are abundant in altered zones. Rb-Sr whole rock age determination establishes the time of emplacement at 285 ± 2 my.
