GENERAL GEOLOGY

Detailed explanation-1: -Cross-cutting relationships is a principle of geology that states that the geologic feature which cuts another is the younger of the two features. It is a relative dating technique in geology.

Detailed explanation-2: -Principle of cross-cutting relationships. The principle of cross-cutting relationships states that a rock unit (or other geological feature, such as a fault) that is cut by another rock unit (or feature) must be older than the rock unit (or feature) that does the cutting.

Detailed explanation-3: -The principle of cross-cutting relationships Any geologic feature that crosscuts or modifies another feature must be younger than the rocks it cuts through. The cross-cutting feature is the younger feature because there must be something previously there to cross-cut.

Detailed explanation-4: -A Cross-cutting relationship is the principle in geology concerning crossing layers. This means that if a dike cuts through a column of sediments, the dike must be younger. It is also possible to look at faults in this manner, to say when the fault was active.

Detailed explanation-5: -Microscopic cross-cutting relationships are those that require study by magnification or other close scrutiny. For example, penetration of a fossil shell by the drilling action of a boring organism is an example of such a relationship.
