Because the bones of Archaeopteryx could not be histologically sectioned in a formal skeletochronological (growth ring) analysis, Erickson and colleagues used bone vascularity (porosity) to estimate bone growth rate. Source: Internet

Compaction reduces the porosity and the pore sizes. Source: Internet
Controlling annealing temperature is another method of reducing or eliminating porosity. Source: Internet
If a rock unit of low porosity is highly fractured, it can also make a good aquifer (via fissure flow), provided the rock has a hydraulic conductivity sufficient to facilitate movement of water. Source: Internet
