Three hundred square miles of the Blue Ridge Mountains of the central portion of the Appalachians, lie within Shenandoah giving the park its color and beauty. This color is caused by the minerals present in the rock, primarily chlorite, actinolite, albite, epidote, titanite, quartz, and magnetite. The actual faults in Shenandoah are often covered by sediments, soil, or rocks, so it is rare that we see them, but when we do, the rock at the fault boundary, which is subjected to massive amounts of pressure, is often pulverized into either fault breccia or fault gauge. The most productive and largest mine, the Crimora Mine, which was an open-cut manganese mine, can be observed along Skyline Drive at the Crimora Lake Overlook. However, human activity, like the burning of fossil fuels, also increases the concentration of these compounds in the atmosphere. ), (Credit: Gary Fleing, VA DCR DNH .

Jointing occurs not because of mineral planes, but because of regional pressures on the rock that cause it to break and move apart slightly. To put that into perspective, the Earth is about 4.5, so these rocks are roughly a whole quarter of the age of Earth itself! Acidity is measured by pH, which is a scale from 0-14, where lower numbers are more acidic and higher number are more basic (alkaline).
