What type of porosity would you expect to be most common in granite?

Question

Quizplus · Accepted Answer

Granite is an igneous rock that typically has very low porosity due to its formation from the cooling and solidification of magma. The primary spaces where fluids can reside or flow are fractures that develop due to tectonic or thermal stresses after the rock has solidified. Intergranular (between grains) and vuggy (pores formed by the dissolution of minerals) porosities are not characteristic of granites, as the grains in granite are interlocked and it is not typically subject to dissolution processes that create vugs.
