Question

Question 75 5 pts Determine the age of the zircon mineral grain from a granite in the Sierra Nevada using the 14C to 14N method. The mineral has 5678814C atoms and 87655 14N atoms. The half life (T1/2) of this system is 5730 years. What is the age? Use the curve equation T = -1.4431n(f) 1. Determine Pi, initial parent amount (add Parent Daughter) 2.f P/Pi 3. Use the curve equation to solve for T (number of half lives elapsed) 4. Use the age equation to determine age. Age = T (T1/2) 7721 Ma 7719 years 700,252 years 5280 years
