Wat is de kleur basalt?
De meest voorkomende mineralen in basalt zijn amfibool, pyroxeen-olivijn en Ilmeniet. Ook andere mineralen, zoals magnetiet kunnen in basalt gevormd worden. Basalt is meestal zwart van kleur en bestaat uit kleine kristallen. De intrusieve variant van basalt wordt gabbro genoemd.

What is basalt?
Summary What is Basalt? Basalt is darker and consists of fine-grained minerals such as magnesium and iron. We can name basalt rocks as mafic rocks as well, just because of this property. Those who know the symbols of magnesium (Mg) and iron (Fe) will easily understand the logic behind the word mafic rocks.
What is the difference between granite and basalt?
On the other hand, granite occurs above the ocean and makes up much of continental crust. Basalt is an extrusive igneous rock, whereas granite is an intrusive ingenuous rock.
Why is basalt sensitive to weathering?
Some of the minerals composing basalt, such as olivine, are very sensitive to chemical weathering at Earth’s surface because of the presence of water. Basalt forms at the surface where it will harden from lava. Places where basalt is abundant include mid oceanic ridges, hot spots, and rift basins.
What is a mid-oceanic-ridge basalt deposit?
It is at the mid oceanic ridges where new oceanic crust is formed. The upper 1-2 km of the oceanic crust is basalt. The basalt that forms at the mid oceanic ridges has a specific composition that makes it distinctive, as a result, basalt deposits that form at the mid oceanic ridges are called MORB (Mid-Oceanic-Ridge-Basalt) deposits or MORBs.
