However, the layer of that material will become thinner as the amount of material lessens away from the source. These foreign bodies are picked up as magma or lava flows, and are incorporated, afghan later to cool in the matrix. Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.


The succession of events in order of relative age that have produced the rock, structure, and landscape of a region is called the geologic history of the region. Finding the key bed in these situations may help determine whether the fault is a normal fault or a thrust fault.

He also realized that a particular assemblage can be found only in a limited interval of strata, and not above or below this interval. The lateral variation in sediment within a stratum is known as sedimentary facies.
