  • Sedimentary rock - Fabric | Britannica

    Sedimentary rock - Sedimentary rock - Fabric: The fabric of a sedimentary rock controls the rock's porosity and permeability and therefore its ability to hold and/or transmit fluids such as oil and water. The orientation, or lack thereof, of the crystals or grains that make up a sedimentary rock constitutes one aspect of fabric. Genetically, there are two principal varieties of oriented ...

    Sedimentary rock - Sedimentary rock - Sedimentary rock types: Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix. Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts are angular or subangular.

  • Igneous rocks

    Igneous rocks are mostly classified on the basis of their composition (either mineralogical or chemical), but there are a number of exceptions where classification is based on texture. Plutonic rocks (coarse-grained igneous rocks that solidified in the crust) are usually classified according to their mineralogical composition.
