Egypt and how they relate to the concept of circumscription. Layout of giza pyramids complexes relates to the. Measurement of the product of the radioactive decay of an isotope of potassium (k) into argon (ar) Used with tuffs (layers of volcanic ash) Carbon has a half-life of 5000-6000 years; Cannot be used in africa (no volcanic activity) Accumulation of argon from decay of potassium at a known fixed rate; argon set to zero as the result of heat of a volcanic eruption. Argon is volatile, all the lava is driven out during a volcanic eruption, Argon picks up over time through the decay of potassium. If i measure the amount of argon relative to potassium in my specimen, i can figure out the time passed since that specific volcanic activity. Useful for very old sites where there is volcanic activity. Carbon isotope in the bone represents when the animal was living.
