How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?

Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?

Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.


Light colored igneous rocks are less what than dark igneous rocks?

basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter


What kind of rocks make up most of the igneous group?

Basalt and other dark colored igneous rocks are the most with % of 66% and granite and other light to medium colored igneous rocks fill the other half with 44%


Why are dark colored igneous rocks heavier than light colored ones?

As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent. As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.

What is the difference between acidic and basic igneous rock?

Acidic igneous rocks are composed of high percentage of silicic materials (minerals) and are light in colour while the Basic igneous rocks are contains predominantly ferromagnesian minerals\materials, they have very little proportion of silica and are dark in colour.
