Summary of basalt vs.
Granite vs basalt density.
Basalt and granite are two types of igneous rocks that we can find on earth.
Basalt wikipedia wikimedia foundation 13 sept.
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.
Gabbro s density ranges from 2 7 3 3 g cm 3.
The hardness of granite is 6 7 and that of basalt is 6.
As it turns out most of the ocean floor is basalt and most of the continents are granite.
And not all granites basalts and gabbros contain exactly the same minerals.
Appearance of granite is veined or pebbled and that of basalt is dull and soft.
This is measured either as a decimal between 0 and 1 or as a percentage.
This comparison allows the students to make some necessary connections between.
Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors.
Basaltic crust is dark and thin and heavy while granite is light and accumulates.
In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent.
Summary basalt vs granite.
Properties of rock is another aspect for granite vs basalt.
It forms from lava flows which extrude onto the surface and cool.
Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
It is common both on earth and other planetary bodies.
Granite is a felsic rock meaning that it has a high silicon content.
Its principle minerals include pyroxene feldspar and olivine.
This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains.
Porosity and density.
It is mostly made out of quartz mica and feldspar.
Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.
This station engages the students in a density problem by asking them to calculate the density of granite and basalt.
