Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering.Rocks like these contain mostly black, white and/or gray minerals. 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. Which process could lead most directly to the formation of a sedimentary rock? Terms in this set (20) Which sedimentary rock has the smallest grain size? Composition: clastic, chemical, or organic. Sediment is broken up pieces of rock that is formed when rocks break down. sedimentary rocks usually form a thin layer over large areas of the continents . Thirty major, minor and trace elements were determined using atomic absorption spectrometry, flame emission … This link will provide you with a downloadable (and printable) pdf of the earth science reference tables.
