Primary porosity examples

WebThe above examples are fundamentally related to the adsorption in the primary porosity [100]. The utility of the adsorption in the secondary porosity [ 100 ] is evidenced in the use of natural and synthetic zeolites as solid electrolytes, since the cationic conduction of zeolites is highly enhanced by the adsorption of water in the secondary porosity [ 15 , 101 ]. http://quebec.hwr.arizona.edu/classes/hwr431/2006/Lab1.pdf

WebAnswer: Thalbert McGinness, Cynical curmudgeon Answered Aug 2, 2024 In my 40 years of rock property work I’ve seen, heard of or worked on several different named porosity types … WebAs with porosity, earth materials have an initial hydraulic conductivity when originally formed and secondary hydraulic conductivity that develops after their original formation. Hydraulic conductivity can increase as a result of weathering, fracturing, jointing, and faulting; and can decrease as a result of mineral precipitation, and at times as a result of weathering. lvt cork backing https://impactempireacademy.com

WebJan 1, 2024 · The sample sets measured in this study have provided quantitative evidence of the different pore surface area exhibited by primary and secondary porosity in sandstones. At the maximum resolution, the secondary porosity exhibits about 2.5 x the pore surface area of the primary porosity, for equivalent pore volume. WebFor most rocks, porosity varies from less than 1% to 40%. The porosity of a rock depends on many factors, including the rock type and how the grains of a rock are arranged. For example, crystalline rock such as granite has a very low porosity (<1%) since the only pore spaces are the tiny, long, thin cracks between the individual mineral grains.
