Porosity and Bulk Density of Sedimentary Rocks

In their method pore volume is determined by the pressure and volume relationships of a gas system with and without a rock specimen. Average values for the porosity of sedimentary rocks have been given by Barrell (1914) as: shale, 8.2 percent; sandstone, 14.8 per­ cent; limestone, 5.3 percent; and all sedimentary rocks, 8.5 percent.

Lithography process (video) | Printmaking | Khan Academy

Lithography, from the Greek for "stone printing," is an intricate printmaking process that revolves around grease and water resisting one another. An artist will draw with a greasy material on a lithographic stone, and then chemically treat the stone to etch the drawing into the stone, which can then be inked to produce many impressions on paper. To learn more, check out the list of online ...

What Is the Process of Lithification? - Reference

Mar 26, 2020 · Lithification is the process by which sediment turns into hardened rock. There are three ways in which lithification can occur. These processes are called compaction, recrystallization and cementation. Compaction is a process of lithification that works for finer particles only. Compaction occurs when particles such as clay minerals are compressed.
