The law of included fragments is a method of relative dating in geology.
Principles of Relative Dating. This principle allowed Steno to link identical rocks on opposite sides of a river valley and deduce the history of events mostly erosion that separated them. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault. The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds.
Often, coarser-grained material can no longer be transported to an area because the transporting medium has insufficient energy to carry it to that location. Layers of sediment do not extend indefinitely rather, the limits can be recognized and are controlled by the amount and type of sediment available and the size and shape of the sedimentary basin. The lateral variation in sediment within a stratum is known as sedimentary facies. His own ideas of what was important were quite different, but I think they are still well worth considering.

The other principles are often called Steno's Laws, but this one stands alone at the foundation of crystallography. Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.
Discover how geologists study the layers in sedimentary rock to establish relative age. Sorby was the first to document microscopic melt inclusions in crystals. The same idea applies to fault lines that slide rock layers apart from each other a fault that cuts across a set of strata must have occurred after the formation of that set.
