| The '''temporal extent''' of the [[petroleum system]] is shown on the events chart and includes the age of the essential elements and processes, the preservation time, and the critical moment. By displaying together the time over which these separate events took place, the relation between forming and charging the traps containing the accumulations is easily evaluated. | | The '''temporal extent''' of the [[petroleum system]] is shown on the events chart and includes the age of the essential elements and processes, the preservation time, and the critical moment.
