WebScientists date igneous rock using elements that are slow to decay, such as uranium and potassium. By dating these surrounding layers, they can figure out the youngest and … WebFor rock unit C: P o = 839 parent atoms P t = 2517 parent atoms (P o /P t) = 0.33 Age = (1.30 billion years) x ln[(0.33) + 1] = 2.09 billion years; Therefore, the age of rock unit C is approximately 2.09 billion years. In conclusion, radiometric dating is a powerful tool for determining the ages of rocks and minerals. highley ward shropshire
