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.asalt is the foundation of oceanic crust. Granite is an intrusive igneous rock made from visible mineral crystals, a result of cooling over a longer period of time under the surface of the Earth. Another difference between basalt and granite include their joints.
Basalt is an extrusive igneous rock with small mineral crystals, formed when magma cools and solidifies rapidly; this is usually on the surface of Earth's crust, especially at incidents of seafloor spreading on the ocean floor as contact with seawater cools the magma rapidly.asalt is the foundation of oceanic crust.
