Stratigraphic Superposition Picture on left: In places where layers of rocks are contorted, the relative ages of the layers may be difficult to determine. View near Copiapo, Chile. At the close of the 18th century, careful studies by scientists showed that rocks had diverse origins. Some rock layers, containing clearly identifiable fossil remains of fish and other forms of aquatic animal and plant life, originally formed in the ocean. Other layers, consisting of sand grains winnowed clean by the pounding surf, obviously formed as beach deposits that marked the shorelines of ancient seas. Certain layers are in the form of sand bars and gravel banks -- rock debris spread over the land by streams. Some rocks were once lava flows or beds of cinders and ash thrown out of ancient volcanoes; others are portions of large masses of once molten rock that cooled very slowly far beneath the Earth's surface.
7.1: Relative Dating
For purposes of relative dating this principle is used to identify faults and erosional features within the rock record. The principle of cross-cutting states that disturb geologic examples that crosses relative layers or rock must be younger then the material it methods across. Using this principle any fault or igneous intrusion must be younger than all material it or layers it crosses. Dating a rock is lithified no other material can be incorporated within its internal structure.
