Which of the following materials probably has the highest permeability?
A) highly fractured granite
B) compacted clays with moderate porosity
C) highly porous volcanic rock with holes that are isolated from one another
D) granite with sparse fractures that are filled with insoluble material

Question

Quizplus · Accepted Answer

Highly fractured granite likely has the highest permeability because the fractures provide pathways for fluid to move through the rock, unlike the other options where porosity does not necessarily translate to high permeability due to isolation or blockage of pores.
