Pore Structure

Abstract

Interstice; Void DefinitionA pore is a small open space or passageway existing between solid materials in a rock, also called a void or an interstice. Generally, pores primarily form at the same time as the formation of the host rock and/or are secondarily introduced by mechanical failures and/or chemical actions after rock formation. From their morphological features, pores can be classified into isolated pores and connected pores. Usually, the pore structure is described in terms of the geometrical features, including their shape, size, volume, connectivity, and tortuosity, of pore populations rather than an individual pore.
