How did the state of North Carolina develop?
What caused the formation of the geologic belts within North Carolina?
What type of rocks would you expect to find within each belt (physiographic province)?

Geologic Belts: Areas with similar rock types and geologic history
Brevard Fault (blue ridge escarpment)
Inner Piedmont Belt: most deformed/metamorphosed portion of the Piedmont, rocks are about 500 – 700 myo (Iapetus Rocks)
Rocks
Gneiss andSchist with (younger) granitic intrusions

Carolina Slate Belt: consists of heated and deformed volcanic and sedimentary rocks (gondwana terranes)
Rocks
granite, argillite, slate, schist, phyllite, gneiss, quartzite, and gold

Triassic basins: the basins are filled with sedimentary rocks about 190-200 mya.
Rocks
conglomerate,sandstone,mudstone
