Process Of Granite By Lava

Granites and lava flows would be good examples of the two different types of igneous rocks everywhere except in en wiki bad science.
Process of granite by lava. The mineral composition of granite usually gives it a red pink grey or white color with dark mineral grains visible throughout the rock although many types of extraordinary granites include colors like blue green black and gold. When you visit a granite showroom these slabs are typically what you will be shown. A granite while igneous is not by definition a lava flow. Lava magma molten rock emerging as a liquid onto earth s surface.
The term lava is also used for the solidified rock formed by the cooling of a molten lava flow. A technician will use milling machines to cut and polish the granite. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm. Hence it s used by nearly an endless amount of cultures.
When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. Lava which is exceedingly hot can be very fluid flowing almost like syrup or it can be extremely stiff scarcely flowing. Once the stone is cool it becomes porous and black creating the beautiful black color so many have come to love. It is usually composed primarily of the minerals quartz feldspar and mica.
Granite contains long and platy minerals that are not initially aligned but when enough pressure is added those minerals shift to all point in the same direction while getting squeezed into flat sheets. Once milling has been completed the slab will be between 7 and 9 feet long. In short your granite kitchen countertops were molten lava at one point. After the mining process is complete the granite will be sent to a workshop to be transformed into slabs.
Granites are intrusive igneous rocks. Lava stone is easily the oldest and most frequently found stone in the world. Granite is an igneous rock that forms when magma cools relatively slowly underground. Today s we re taking a comment request and seeing if we can successfully melt lava rock and then possibly cast with it.
Igneous rocks that are not molten at or near the surface whereas lava flows are extrusive igneous rocks rocks. Consider how granite changes form.
