Thus both the geologic dating methods on samples ranging from prehistoric fossils can learn more about it cannot be dated. This happens, for example, where animal burrows penetrate into pre-existing sedimentary deposits.
Geomorphological relationships may occur where a surficial feature, such as a riverflows through a gap in a ridge of rock. In a similar example, an impact crater excavates into a subsurface layer of rock.
Cross-cutting relationships may be compound in nature. For example, if a fault were truncated by an unconformity, and that unconformity cut by a dike. Based upon such compound cross-cutting relationships it can be seen that the fault is older than the unconformity which in turn is older than the dike. Using such rationale, the sequence of geological events can be better understood.
Cross-cutting relationships - Wikipedia
Scale[ edit ] Cross-cutting relationships involving an andesitic dike in Peru that cuts across the lower sedimentary strata. Both the dike and the lower strata are cut by an unconformity A light-gray igneous intrusion in Sweden cut by a younger white pegmatite dike, which in turn is cut by an even younger black diabase dike Cross-cutting relationships may be seen cartographicallymegascopicallyand microscopically.
In other words, these relationships have various scales. A cartographic crosscutting relationship might look like, for example, a large fault dissecting the landscape on a large map. Megascopic cross-cutting relationships are features like igneous dikes, as mentioned above, which would be seen on an outcrop or in a limited geographic area.
