Answer

Brief Explanations:

Index fossils are used for relative - age dating based on the presence of specific fossils in rock layers. The law of superposition and the law of original horizontality are also principles for relative - age dating, stating that in undisturbed rock sequences, older rocks are at the bottom and sedimentary rocks are originally deposited horizontally. Radiometric dating is a technique that measures the decay of radioactive isotopes in rocks to determine their absolute age. Since we want the absolute age of a Precambrian igneous rock, radiometric dating is the best method.

Answer:

radiometric dating
