Relative dating meaning noun
In a series of undisturbed layered rocks each successive layer above is younger than the layer below it. Therefore, the oldest rocks are at the bottom of the sequence and the youngest are at the top. There are four types of unconformities, as summarized in Table 7.1, and illustrated in Figure 7.2.5. The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds.
Exercise thirteen dating of rocks and geologic events
The principle of inclusions states that any rock fragments that are included in a rock must be older than the rock in which they are included. For example, a xenolith in an igneous rock, or a clast in sedimentary rock must be older than the rock that includes it (Figure 19.8). When investigating rocks in the field, geologists commonly observe features such as igneous intrusions or faults that cut through other rocks. Because these features are the ones doing the cutting, we know that they are younger than the rocks that they cut into. There are a variety of scientific methods that archaeologists use to analyze the age and origins of fossils, remains, or other artifacts. Dating methods can enable bio-archaeologists to determine factors such as environment, diet, health, or migration patterns of humans, plants, or animals.
