In general, sandstones lose porosity with age. In other words, porosity loss in sandstone is a function of time. According to Scherer,<ref name=ch09r53 /> a [[Tertiary]] sandstone with a Trask sorting coefficient of 1.5, a quartz content of 75%, and a burial depth of [[depth::3000 m]] probably has an average porosity of approximately 26%. A Paleozoic sandstone with the same [[Core_description#Maturity[sorting]], quartz content, and burial depth probably has an average porosity of approximately 13%.
