When there is an igneous intrusion and a fault line which one is younger?

That depends! If the fault line cross cuts the igneous intrusion causing the intrusion to be displaced on either side of the fault and forming a broken mass of rock within the intrusion known as a fault breccia then the fault is younger than the intrusions, as the intrusion must have already existed for the fault to cause it's displacement. If on the other hand the igneous intrusion cross cuts the fault and is un-deformed then it is probable that it is younger than the fault.
