What are the main differences between granite and basalt? Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% SiO2, whereas granite is 73%. Intrusive, slowly cooled inside the crust.

Is granite the hardest rock? Granite is an igneous rock known for being very hard. Quartzite, on the other hand, is a metamorphic rock composed almost entirely of quartz ...

Basalt is more glassy and porous than andesite. Basalt is the precursor to andesite. The cooling process removes minerals from the melt to form andesite, in which case the holes contain zeolite (or some other mineral). Basalt will have defined pores and be very dark.

Basalt is not harder than the other rocks. For some reason, some people think basalt is a harder rock. The rocks are a mixture of minerals, each mineral having its own hardness. Of the three rocks, granodiorite is the rock with the hardest mineral in it, because it is the only rock of the three that has some quartz in it, which is harder than ...
