Which Cools Faster Granite Or Basalt

Basalt is often compared to granite since both stones are igneous rocks.

Which cools faster granite or basalt. Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors. Yes the obsidian does cool quickly and the vesicular basalt. It s very fine grained and it s difficult to determine its exact mineral composition. The hardness of basalt is 6 and that of obsidian is 5 5 5.

Basalt forms when magma from the ocean surfaces through the crust. Basalt can form in a few days to months whereas granite plutons can take millions of years to cool and harden. As it turns out most of the ocean floor is basalt and most of the continents are granite. All rocks of igneous origin consist of magma or molten earth that finds its way up to.

And has a glassy texture. Granite cools very slowly that s why it shows coarser. Properties of rock is another aspect for basalt vs obsidian. It wants to be there and heat is the key which unlocks the door.

Basalt is more common in oceanic crust while granite is more common in continental crust. Granite is of intrusive origin which means the. It is this bit of information that makes basalt a great choice for installations in homes and buildings easy maintenance. Smaller grain size is associated with faster cooling.

Both of these stones mostly do not contain calcium carbonate and typically do not react to acids. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of. Appearance of granite is veined or pebbled and that of basalt is dull and soft.

The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. I think obsidian is a supercooled liquid of a magma its look like a glassy matter because is crystallised very faster than basalt and granite. Appearance of basalt is dull and soft and that of obsidian is shiny. Basalt cools very quickly in a few weeks or months which leaves little time for crystals to form.

Basaltic crust is dark and thin and heavy while granite is light and accumulates. Summary of basalt vs. Basalt is available in black brown light to dark grey colors whereas obsidian is available in black blue brown green orange red tan yellow colors.
