What is harder basalt or granite? Quora

1 Definition Granite is a very hard, granular, crystalline igneous rock which consists mainly of quartz, mica, and feldspar and is often used as building stone Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of EarthGranite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks Basalt forms when lava reaches the Earth's surface near an active volcano The temperature of lava is between 1100 to Granite vs Basalt Compare NatureGranite, much lighter in color than basalt, contains high amounts of quartz Quartz is a glaslike mineral and very hard with no cleavage or weak spotsOrthoclase has 90degree cleavage and is pink, white and shades of gray It contains large amounts of quartz in some areas, making it harder Why Does Basalt Weather Faster Than Granite? SciencingAug 14, 2011 Of the two, basalt is darker and consists of finegrained minerals such as magnesium and iron while granite is lighter and consist of feldspar and quartz Among other differences, the nature of these rocks reveals that basalt is basic in nature, whereas granite is acidic in natureDifference Between Basalt and Granite Compare the May 05, 2007 The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basaltis basalt harder than granite?

Why Does Basalt Weather Faster Than Granite? Sciencing

Granite, much lighter in color than basalt, contains high amounts of quartz Quartz is a glaslike mineral and very hard with no cleavage or weak spotsOrthoclase has 90degree cleavage and is pink, white and shades of gray It contains large amounts of quartz in some areas, making it harder Both basalt and granite are types of rock, and a rock is composed of multiple minerals except for some rocks composed of essentially one mineral like limestone (calcite) or quartzite (quartz)Which is harder basalt or granite? AnswersAug 14, 2011 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 Earth contains three kinds of rocks namely igneous rocks, sedimentary rocks, and metamorphic rocksBasalt and granite are two types of igneous rocks All rocks of igneous origin consist of magma or molten earth that finds its way up to Difference Between Basalt and Granite Compare the Basalt is volcanic, or extrusive, forming at the surface, while granite is plutonic, or intrusive, forming beneath the surface Basalt is mafic while granite is felsic Basalt is common on both Earth and other Solar System bodies such as the Moon and Mars while granite is only common on Earth and rare elsewhere in the Solar SystemDifference Between Basalt and Granite Difference BetweenMay 06, 2007 The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt The resistance to breaking of a rock (which could be confused with the apparent hardness to a nonexpert) is greatly affected by fractures, weathering, induration, welding is basalt harder than granite?

Granite Hardness: How Hard is the Natural Stone? Marble

Sep 24, 2019 Granite comes in at a 6 to 7 on the Mohs scale, meaning it is relatively hard The igneous rock is comprised of mostly quartz and feldspar, along with smaller amounts of various other minerals An example of the hardness of a granite countertop can be seen in Granite also "floats", if you will, because despite its toughness, it's not dense like basalt, the rock of the oceans Now the question for continental makeup in an alternate Earth is thisis there a tough but still buoyant alternative to granite, preferably a rock tougher to resist against erosion than granite itself?hard science Tougher Alternative Than Granite Scoria is available in black, brown, dark grey to black, red colors whereas, Basalt is available in black, brown, light to dark grey colors Appearance of Scoria is Glassy and Vesicular and that of Basalt is Dull and Soft Properties of rock is another aspect for Scoria vs Basalt The hardness of Scoria is 56 and that of Basalt is 6Scoria vs Basalt Compare NatureApr 17, 2017 Metaquartzite That is an old classification and I am not sure the classification still exists But in the 1960s when I began learning rock classification a quartzite was a sandstone that was composed predominantly of quartz and cemented with siliWhat is the hardest natural stone?

What Is the Difference Between Basalt and Granite?

Apr 04, 2020 Granite is a felsic rock, meaning that it has a high silicon content; it is mostly made out of quartz, mica and feldspar Basalt, as a mafic rock, contains more calcium oxide, manganese oxide and iron compounds than granite Its high iron content gives it magnetic properties, and it may show signs of rust when exposed to airContinents are formed from granite created as basalt plates subducted Granite is less dense than Get Price; which is harder granite or basaltnormanmt building with rocks it then cooled forming granite basalt and dioritegranite is very hard georgia marble is harder to carve and used mainly for architecture which harder granite or basaltGranite will just be a little bit harder than basalt Share Continue Reading Reply Daniel Drake Daniel Drake Answered Jul 31, 2020 Basalt and Granite are two types of indigenous rocks One way to tell them apart is by their color Basalt comes in a darker color than granite Another difference between them is in regards to the surface What is the difference between Basalt and Granite Correspondingly, what are the main differences between granite and basalt? Igneous rocks are formed by the crystallisation of a magma The difference between granites and basalts is in silica content and their rates of cooling A basalt is about 53% SiO2, whereas granite is What is the difference between basalt and andesite?If you would check the amount of silica that can be found in Basalt, it will be 53%, while granite will be about 73% You may also see some differences in the way that they work You will see that granite will be a bit pebbled, but basalt will be soft When it comes to hardness, they are almost the sameWhat is the difference between Basalt and Granite

Yahoo AnswersApr 17, 2017 Granite is a good hard rock and is tough too It is likely the hardest stone used as a building material I think basalt or other trap rocks are hard rocks They are very heavy and toughWhat is the hardest natural stone? QuoraJan 23, 2020 Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its densityThe Density of Common Rocks and Minerals ThoughtCo
