Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro. Oceanic crust is mostly composed of basalt or rocks with the same composition (gabbro, diabase).^ Basanite is a volcanic rock. It is similar to basalt but contains less silica and usually more alkali metals.
In the commercial stone industry, a "granite" is a rock with visible grains that are harder than marble. Under this definition, gabbro, basalt, pegmatite, schist, gneiss, syenite, monzonite, anorthosite, granodiorite, diabase, diorite, and many other rocks will be called "granite."
Granite Granite with mineral composition of feldspar and quartz is a hard igneous rock. Its structure is also different like crystalline. Geologists say that granite comes in many colours. Again, the colour of the rock is largely depends upon the composition of the minerals which basically gives colour to all granite rocks from pink to grey.
Apr 25, 2017· Granite gets its hardness from its quartz content, but quartzite contains more quartz per volume than granite, making it essentially a harder material. Granite is more abundant than quartzite; it is widely distributed throughout the earth's crust and forms the foundation that underlies the sedimentary rock beneath most of the continents.

Basalt is not related to hot temperatures any more than the other igneous rocks, however, basalt is more related to volcanic activity than rocks like granite. This diagram shows the conditions which make igneous rocks (Mafic rocks have higher iron content and felsic rocks have higher quartz, and extrusive/intrusive refers to the cooling rate).
Basalt appears to be slightly denser, and proprotionately stronger, while granite is tougher so it would be a bit harder to mine through.

Mineralogically, granite contains quartz, various feldspars, and micas. Although there are many rocks that resemble granite, they are not all true granites. Thus, plutonic rocks that are compositionally similar to granite but not identical are referred to as granitoids. Diorite is the compositional intermediate between granite and gabbro.
