Main Differences Between Basalt and Granite Basalt is darker colored and is composed of mafic. On the other hand, granite is light-colored and is composed of felsic. Basalt is an extrusive igneous rock that erupts onto the surface where they cool quickly to form small crystals.

What colors does basalt come in?
Basalt is usually dark grey to black in colour, due to its high content of augite or other dark-coloured pyroxene minerals, but can exhibit a wide range of shading. Some basalts are quite light-coloured due to a high content of plagioclase, and these are sometimes described as leucobasalts.
How do you tell the difference 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 73%. ... (Plutonic rock = formed in the earth).
What rock color is granite?
Granite is an intrusive igneous rock with large grains (minerals) easily seen by the naked eye. Granite colors are most commonly pink, white, variations of grey and black.
Can basalt be green?
When you crack open a basalt pebble or cobble, what you usually see is a dark-grey, featureless, fine-grained rock; however, some stones may be dark greenish-grey, dark bluish-grey, or even olive green inside. ... Some basalt looks glassy on the surface, even when dry.
Which is lighter granite or basalt?
Granite, much lighter in color than basalt, contains high amounts of quartz.
What is the color and texture of granite?
Colour: Pink-grey. Structure: Massive, confining. Texture: phaneritic (medium to coarse grained). , holocrystalline, pan-hypidiomorphically grained, porphyric in places. Major minerals of Granite: Orthoclase, quartz, biotite, muscovite and plagioclase, which is twinned according to the albite law and oscillatory zoned.
Is there blue granite?
Granite comes in a huge variety of colors and has a wide choice of patterns. Though many granites are predominately white, pink, or gray, a less traditional color option is blue. Blue granites come from all over the world and are mostly found in Africa, Norway, Brazil, and Ukraine.
What type of rock is a basalt?
Basalt is a hard, black volcanic rock. Basalt is the most common rock type in the Earth's crust. Depending on how it is erupted, basalt can be hard and massive (Figure 1) or crumbly and full of bubbles (Figure 2).
What is the streak color of basalt?
Streak is not really a meaningful test for a rock, although a weathered basalt is likely to give a brownish streak due to oxidation of its iron-rich minerals.
How do you identify basalt?
Basalt appears black or grayish-black, sometimes with a greenish or reddish crust. Feel its texture. Basalt consists of a fine and even-grain. The dense rock has no crystals or minerals discernible to the naked eye.
What Colour is Windspray?
Windspray® is mid-strength, neutral grey with a blue undertone that brings to mind a gentle breeze, soft shadows and the misty sea on a cloudy day.
What is basalt grey?
Included in the Fusion Collection, Basalt Grey is inspired by basalt rock just like the other models in the Basalt range of the same collection. Basalt Grey is different from our Basalt Black as the tone is not as dark with greyish dilution which perfectly combines with all of the other models in the same range.
What Colour is Wallaby?
A warm, earthy and natural mid grey, Wallaby® has a softness that allows it to be paired with a variety of both traditional and contemporary building materials ranging from glass and steel to timber and stone.
