Geologic block diagram of a hypothetical region showing igneous intrusions (K and L), a fault (M), and sedimentary rock layers.1. Answer the following questions using the figure provided below.

1)   Determine the sequence of the geologic events illustrated in the figure. List your answer from oldest to youngest geologic events related to this figure. Note that letters M and N are faults, J, K and L are igneous intrusions, and all other layers are sedimentary rocks.

2)   Given that the ratio between U235 and Pb207analyzed from the granite intrusion (J) is 1:7 and half-life of the dating method is 713 million years. How old is the granite?

3)  Based on the radiometric date you obtained in question 1), what is be the maximum (oldest) age for the basalt dike L?

4)   Using the same dating method (U235 and Pb207), the amount of Pb207 found in layer F is96.875% and the amount of U235 found in layer G is 6.25%. For at least how many million years had the layer F been exposed on the surface to receive weathering and erosion before layer G started to form2. Describe the locations and names for each of the unconformities in Figure 6-5 (in your lab exercise

6) How each of these unconformities differs from one another.
