Igneous Rocks: Basalt and Granite
Granite and basalt are both igneous rocks - they are formed from magma extruded into another rock layer or from expulsion from a volcano. The heat of the cooling rock would completely melt any fossils they came into contact with and destroy them, so you don't see fossils in these rocks.
Rocks have a composition between that of granite and basalt

Basalt and Granite are igneous rocks which are very hard.
Granite and basalt are both igneous rocks; however, basalt is considered a volcanic rock, and granite is considered a plutonic rock.
They are all igneous rocks.
Igneous rocks
Three types of igneous rocks are pumice, basalt, and granite.
Silicates make up close to 95 percent of the rocks in the Earth's crust

Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
