1. Intrusion

   In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California.Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks.Intrusions must displace existing country rock to make room for themselves. The question of how this takes place is called the room problem, and it remains a subject of active investigation for many kinds of intrusions.The term pluton is poorly defined, but has been used to describe an intrusion emplaced at great depth; as a synonym for all igneous intrusions; as a dustbin category for intrusions whose size or character are not well determined; or as a name for a very large intrusion or for a crystallized magma chamber. A pluton that has intruded and obscured the contact between a terrane and adjacent rock is called a stitching pluton.

1. Intrusion

   An intrusion is liquid rock that forms under Earth's surface. Magma from under the surface is slowly pushed up from deep within the earth into any cracks or spaces it can find, sometimes pushing existing country rock out of the way, a process that can take millions of years. As the rock slowly cools into a solid, the different parts of the magma crystallize into minerals. Many mountain ranges, such as the Sierra Nevada in California, are formed mostly by intrusive rock, large granite formations. Intrusions are one of the two ways igneous rock can form; the other is extrusive, that is, a volcanic eruption or similar event. Technically speaking, an intrusion is any formation of intrusive igneous rock; rock formed from magma that cools and solidifies within the crust of the planet. In contrast, an extrusion consists of extrusive rock; rock formed above the surface of the crust. Intrusions vary widely, from mountain-range-sized batholiths to thin veinlike fracture fillings of aplite or pegmatite. When exposed by erosion, these cores called batholiths may occupy huge areas of Earth's surface. Large bodies of magma that solidify underground before they reach the surface of the crust are called plutons.

Examples of intrusion in a Sentence

1. Attorney General Bill Barr:

   You know, putting a national lockdown, stay at home orders, is like house arrest. Other than slavery, which was a different kind of restraint, this is the greatest intrusion on civil liberties in American history.

2. Mike Pence:

   Less than two weeks ago, Finney County, Kansas, reached out to DHS for help after a malware attack forced them to shut down not just their election network, but the entire county's network, federal officials worked hand-in-hand with the county to identify and ultimately eliminate this dangerous intrusion. This is a model of the collaboration that we need to ensure the security of our elections.

3. Daren Bakst:

   Every little bit helps, and by reducing the unwarranted federal intrusion into agriculture, the market might adjust and create a new and possibly significant way of purchasing meat, the coronavirus and recent weather disasters have highlighted the failings of our subsidy system.

4. Harry Browne:

   The income tax is the biggest single intrusion suffered by the American people. It forces every worker to be a bookkeeper, to open his records to the government, to explain his expenses, to fear conviction for a harmless accounting error. Compliance wastes billions of dollars. It penalizes savings and creates an enormous drag on the U.S. economy. It is incompatible with a free society, and we aren’t libertarians if we tolerate it.

5. Jason Potts:

   We are listening to their respiratory pattern. We may hear a little gurgling in their diving apparatus, indicating water intrusion in their helmet, we know each other well. We are listening to the tone of their voice ... the words they are saying. We are listening to their opinions, we are listening to the factual information. We are listening to every single word they say and every breath they take to make sure they are safe on the bottom.
