Answer :
The age of the reef limestones in different locations can be determined using radiometric dating techniques, such as uranium-lead dating or carbon dating.
If the ages of the reef limestones in section 3 and section 7 are found to be similar, then it is likely that they are of the same age. However, there could be local variations in the age of the reef limestones due to differences in geological history or environmental factors.
Radiometric dating is a method used to determine the age of rocks or fossils by measuring the decay of radioactive isotopes within them. The rate of decay is constant, allowing scientists to calculate the age of the sample by measuring the ratio of isotopes present.
Therefore, a detailed geological analysis of the two sections would be needed to determine the age relationship between the massive reef limestones of section 3 and section 7.
