Secondary porosity index
Web(v) Secondary porosity The porosity resulting from diagenesis. (vi) Microporosity The porosity resident in small pores (< 2 µm) commonly associated with detrital and authigenic clays. (vii) Intergranular porosity The porosity due to pore volume between the rock grains. (viii) Intragranular porosity The porosity due to voids within the rock grains. Web21 Aug 2024 · Secondary porosity is the additional porosity acquired after the original rock formation process (Figure 11).
