Coloring:
* Granite: Typically light-colored, ranging from white to pink, gray, or even black. This is due to its high content of quartz and feldspar, which are light-colored minerals.
* Gabbro: Dark-colored, often appearing black, dark green, or dark gray. This is attributed to its high content of dark-colored minerals like pyroxene and plagioclase feldspar.
Silica Content:
* Granite: High in silica, typically ranging from 60% to 75%. This high silica content contributes to its characteristic light color and often results in a coarser, more crystalline texture.
* Gabbro: Lower in silica, typically ranging from 45% to 55%. This lower silica content leads to the darker color and a more fine-grained texture.
In Summary:
* Granite: Light-colored, high silica content.
* Gabbro: Dark-colored, lower silica content.
Here's a simple analogy: Think of granite as being like a "light" bread with a lot of "air" (silica), while gabbro is like a "dense" bread with less "air" (silica).
