Basalt Vs Granite Hardness

Appearance of granite is veined or pebbled and that of basalt is dull and soft.

Basalt vs granite hardness.

For example the scale begins with the softest material talc. 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. The igneous rock is comprised of mostly quartz and feldspar along with smaller amounts of various other minerals. It forms from lava flows which extrude onto the surface and cool.

Basalt is an aphanitic fine grained igneous rock that is relatively low in silica and alkali metals it has less than 10 feldspathoid by volume with at least 65 of the rock consisting of feldspar in the form of plagioclase this places basalt in the basalt andesite field of the qapf diagram basalt is further distinguished from andesite by its silica content of less than 52. It is common both on earth and other planetary bodies. The mohs hardness scale was developed in 1812 by a german geologist and mineralogist friedrich mohs to determine the relative hardness of a mineral as a comparison to another mineral. Properties of rock is another aspect for basalt vs granite.

Basalt is available in black brown light to dark grey colors whereas granite is available in black grey orange pink white colors. Summary basalt vs granite. Grant mason from the byu department of physics and astronomy discusses samples of granite and basalt rock. Its principle minerals include pyroxene feldspar and olivine.

Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey colors. 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. Appearance of basalt is dull and soft and that of granite is veined or pebbled. Granite comes in at a 6 to 7 on the mohs scale meaning it is relatively hard.

Summary of basalt vs. Basalt and granite are two types of igneous rocks that we can find on earth. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Properties of rock is another aspect for granite vs basalt.
