==Effects of pore type and geometry==
Pore type, defined by [[Pore and pore throat sizes|pore throat size]] (i.e., [ http://en.wiktionary.org/wiki/macroporous macroporosity]), directly controls rock [[permeability]]. Pore throat size limits [[Fundamentals of fluid flow|flow capacity]]. Pore geometry also affects permeability, but not as much. The rougher the surface of the pore, the more difficult for fluid to flow through the pore and the lower the permeability.
