The principle of intrusive relationships concerns crosscutting intrusions. In geology, when an igneous intrusion cuts across a formation of sedimentary rock , it can be determined that the igneous intrusion is younger than the sedimentary rock.
Cross-cutting relationships can be used to determine the relative ages of rock strata and other structures. Explanations: A – folded rock strata cut by a thrust fault; B – large intrusion (cutting through A); C – erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D – volcanic dike (cutting through A, B & C); E – even younger rock strata (overlying ...
Depending on the composition of the magma, the intrusive body may have a complex internal structure which can provide insight into its emplacement. The country rock responds to the immense heat from the intruding body in numerous ways. Chill margins are created if the magma is cooled too quickly to fully crystallise.
A fundamental principle of geology advanced by the 18th-century Scottish physician and geologist James Hutton is that "the present is the key to the past." In Hutton's words: "the past history of our globe must be explained by what can be seen to be happening now." [18] The principle of intrusive relationships concerns
The principles of lithostratigraphy were first established by the Danish naturalist, Nicolas Steno, in his 1669 Dissertationis prodromus. [1] A lithostratigraphic unit conforms to the law of superposition, which in its modern form states that in any succession of strata, not disturbed or overturned since deposition, younger rocks lies above older rocks.

Obsessive relational intrusion (ORI) occurs when someone knowingly and repeatedly invades another person's privacy boundaries by using intrusive tactics to try to get closer to that person. It includes behaviors such as repeated calls and texts, malicious contact, spreading rumors, stalking, and violence (kidnapping and assault).
Interdependence theory is a social exchange theory that states that interpersonal relationships are defined through interpersonal interdependence, which is "the process by which interacting people influence one another's experiences" [1] (Van Lange & Balliet, 2014, p. 65).
Engraving from William Smith's monograph on identifying strata based on fossils. Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment.
