porositylike

Porositylike is a term used in materials science and geoscience to describe features or signals that resemble porosity but do not meet conventional definitions of pore space. It denotes void-adjacent morphology or imaging signals that mimic pores yet may not function as true storage or transport pathways for fluids.

True porosity is the fraction of a material's volume that comprises interconnected void space capable of storing and transmitting fluids. Porositylike features may be closed, isolated, disconnected, or non-permeable, and may arise from imaging artifacts, microcracks that do not connect, or phase boundaries that create low-density regions in reconstructions.

Because of these differences, porositylike is typically described as a morphological or qualitative descriptor rather than a quantitative measure of pore space. When reporting data, researchers distinguish porositylike regions from actual porosity and may apply separate metrics to assess connectivity, permeability, or communication with the surrounding environment.

Applications include interpretation of scans in geology, petroleum engineering, ceramics, and composite materials, where distinguishing porositylike voids from real porosity affects estimates of permeability, mechanical properties, or fluid storage.
