Intrusive igneous rock.
batholith
After a magma chamber and its conduit have solidified and been exposed by erosion, it is referred to as a "pluton." Specifically, if the solidified magma forms a large, irregular mass, it may be called a "batholith." These geological features are typically found in mountainous regions and provide insights into the Earth's geological history.
A volcanic conduit that has solidified and been exposed by erosion is called a volcanic neck or volcanic plug. These features are made up of solidified magma that once flowed through the conduit of a volcano.
Cooled and solidified magma that rests below the surface becomes intrusive igneous rock. When magma is erupted onto the surface, then cools and solidifies, it becomes extrusive igneous rock. The major rock classification for cooled magma or lava would be IGNEOUS.
It doesn't. The volcano is a result of the magma travelling from the earths core through geological faults and breaking through the crust of the Earth. The mountain shaped Volcano that you see is the remnants of solidified ash and magma (pumice) which has been ejected from the magma chamber. This cone builds up over the fissure which ejects the magma onto the surface.
Minerals such as quartz, calcite, and pyrite can crystallize out of ground water that has been heated by magma. These minerals form as the water cools and the dissolved minerals in the water precipitate out and form solid crystals.
A volcanic neck forms when the volcano has long since been extinct. The once molten magma that is in the former eruptive vent of the volcano cools and solidifies over time. Once the magma is solidified long after extinction of the volcano erosional forces take over on the volcano. Over time the volcano becomes more and more dissected. Once the older layers of the volcano are eroded away all that will remain is the erosion resistant solidified magma that was in the now ancient volcanoes vents.
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
Intrusive rocks are Igneous rocks that have been formed underground. Igneous rocks are formed by the cooling of lava/magma. Igneous rocks are divided into two categories- intrusive and extrusive. Intrusive is when the magma cools slowly beneath the Earth's surface, which causes large crystals to form. When lava cools above the Earth's surface, it is called extrusive. Extrusive rocks have smaller crystals compared to intrusive, the difference always being noticable.
Magma rocks and lava rocks are both formed from molten rock beneath the Earth's surface. They both originate from the same source material but differ in their location and state - magma rocks are found below the surface, while lava rocks are formed when magma reaches the surface and cools.
Here are more than two- Galena, Gold, Copper, Sulfur, Pyrite.
Quartz and calcite are two minerals commonly found crystallizing out of ground water heated by magma. Quartz forms from the cooling of silica-rich solutions, while calcite forms from the precipitation of calcium carbonate in hot hydrothermal environments.
