 (pə-rŏs′ĭ-tē, pô-)
n. pl. po·ros·i·ties
1. The state or property of being porous.
2. A structure or part that is porous.
3. The ratio of the volume of all the pores in a material to the volume of the whole.

n, pl -ties
1. the state or condition of being porous
2. (Geological Science) geology the ratio of the volume of space to the total volume of a rock
[C14: from Medieval Latin porōsitās, from Late Latin porus pore2]


(pɔˈrɒs ɪ ti, poʊ-, pə-)

n., pl. -ties.
1. the state or quality of being porous.
2. (in rock or other natural material) the ratio of aggregated pore space to the volume of the entire mass: used as a measure of the amount of fluid, as oil, that a geologic stratum might hold.
[1350–1400; Middle English porosytee < Medieval Latin porōsitās. See porous, -ity]

In general, the relatively large magnitude of the standard deviations with respect to the average porosities agree with the results found in Ref.
The absolute porosities are the proportion of total empty space of sample to the volume of total mass, without attending if they have internal relation or not.
Similarly to assigning porosity values to the results of the fuzzy K-means clustering classification, classes with higher altitudes and slopes were assigned lower porosities and classes with lower altitudes and slopes were assigned higher porosities.
Using the weights of the dry sediment and the water, total porosities were calculated for each sediment size.
Strawn limestone porosities are typically very low.
In sample 4 we can observe practically only contraction porosities, and a reduced gaseous porosity as a result of hydrogen supplementary elimination staying in the melt.
