Answer to Problem 1GST

The sequence of formation of features present in the image from older to younger is Gneiss, dike, fault. Gneiss is metamorphic and must have formed before the dike, otherwise the igneous dike would have been metamorphosed also. The fault has split and separated the dike, therefore the dike must have formed before the fault occurred.

Explanation of Solution

According to the principle of cross-cutting relationship, the igneous dike is younger and formed after the metamorphic rock Gneiss that cuts through it. Gneiss is a high grade foliated metamorphic rock and must have formed before the dike, otherwise the dike would have been metamorphosed too. The fault has split and separated the dike, hence the igneous dike must have formed before the fault occurred.
