Examplesofporosityporosity We shall assume that theporosityis the same in the two media. From theCambridge English Corpus The arrangement of particles has given the samples highporosity, the pores are wide and fluids are therefore free to move, making the samples permeable. From theCambridge English Corpus This large effectiveporosityallows the ingress of water within the grains, with potential damage to the grain upon freezing and thawing. From theCambridge English Corpus The difference between scenarios (c) and (d) will be related to theporosityof the regolith. From theCambridge English Corpus He saw no major difficulties in postulating peripheral porosities for the blood to circulate, although he could not visualize them for the time being. From theCambridge English Corpus However, there are many factors that would affect the thermal conductivity, including the rock type, its mineral composition andporosity. From theCambridge English Corpus It is clear from these results thatporosityis not the sole criterion for rock colonization by micro-organisms. From theCambridge English Corpus As well as the mineralogy of the sample, the textures (grain size, shape,porosity) were determined. From theCambridge English Corpus It also looks at erosional processes, and very briefly at carbonate rock description andporosity. From theCambridge English Corpus Compaction increased soil bulk density and penetration resistance and decreasedporosityand per meability. From theCambridge English Corpus The present day petrography of this formation shows a medium-grained and well-sorted quartzite with syntaxial quartz cements and virtually zeroporosity. From theCambridge English Corpus Secondaryporositydevelopment (alarmingly called decompaction!) is thought to result from carbonate solution by carbonic acid formed by decarboxylation during early stage hydrocarbon generation. From theCambridge English Corpus Theporosityvalues of the ceramics and soil were estimated to be 15% and 30%, respectively. From theCambridge English Corpus Under low stresses, grain fracturing may be absent and deformation is accommodated also by grain rotation, grain sliding andporosityreduction. From theCambridge English Corpus Along with a measure of humidity, this is related to theporosityof the medium.
