A sedimentary rock sample consists of 40 % sand (density 2.65 g cm\(^{-3}\)), 30 % silt (density 2.70 g cm\(^{-3}\)) and 30 % clay (density 2.58 g cm\(^{-3}\)). Initially the rock has a porosity of 40 %. After compaction the porosity reduces to 25 % while the mineral volumes shrink proportionally to the loss of pore space.
