What geologic law is applied if an igneous intrusion is observed through a layer of sedimentary rock?
law of crosscutting relationships.
Can you explain how intrusions affect rock layers?
Intrusions occur when magma cuts through weaknesses in rock layers and forms a band of igneous rock. Sometimes the new band is approximately horizontal and it is called a sill. If it is more vertical it is called a dyke.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above. The solidified intrusions and lava flows can be dated with radiometric techniques.The radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their sedimentary counterparts, therefore allows the sedimentary rock to be dated as well.
How is a igneous is formed what is igneous rocks?
Igneous rock is formed through the rock cycle. The igneous rock is formed by magma and lava,then it goes through volcanic activity.
What are theApplication of thermodynamics on igneous petrology?
used in the study of Igneous rocks and Metamorphic rocks in their temperature and Pressuse Well I think is applied in almost everything. Ore Deposits, Geochemistry, Igneous Petrology, Metamorphic geology, geochronology, environmental geology, aqueous geochemistry, environmental pollution, phase equilibria, in all natural systems is applied thermodynamics, if you are good in thermodynamics you are in good shape to study natural systems i.e. geologic systems.
What are the Igneous intrusions injected between horizontal layers known as?
Igneous intrusions that are concordant (parallel to bedding planes of country rocks) are known as sills, whereas dykes cut through the bedding.

Why is there so much copper in Arizona?
The initial source for copper in Arizona were igneous intrusions into native host rock. The copper veins were eventually exposed through erosion at the surface. Copper then leached back into the ground and recrystallized in the form of copper minerals in what is called a supergene enrichment zone. The igneous intrusions were due to a long period of magmatism from the middle of the Mesozoic to the early Cenozoic era.

What is the environment of quartzite?
Quartzite is a Metamorphic Rock that undergos extreme heat and pressure forcing pre-existing rocks to recrystalize. It forms through contact metamorphism. It's formed at an igneous intrusion cutting through existing rock in a small area; usually along cooled igneus intrusions.
Why is an igneous intrusion younger than the rocks in which it is found?
The melted rock of the igneous intrusion pushed its way into cracks and made previously existing rock weaker. The intrusions only became rock when they cooled and solidified, therefore they are younger than the rocks in which they are embedded.
What is the main concept behind the rock cycle?
The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous
How is a igneous is formed what is igneous rocks?
Igneous rock is formed through the rock cycle. The igneous rock is formed by magma and lava,then it goes through volcanic activity.
What geologic activities created southeast Asia's?
rivers create trsansportation routes through lush vegetation, majestic volcanoes add to the scenery, these physical features create Southeast Asia>
How does a igneous rock turn into a igneous rock?
An igneous rock is formed when magma rises through the earth's crust and cools.
