Web1.3 Porosity The empty spaces in between the crystals or fragments that make up a rock represent porosity that can hold water. Porosity is a measure of how much water a body of rock can hold, expressed as a percentage of t rock’s volume. The spaces between the grain crystals of a rock are referred to as intergran porosity. WebThe Chlorite schist shows a neutron porosity of about 50 porosity units and a bulk density of about 2.5 gm/cc; Schlumberger tabulated values for pure chlorite are a neutron porosity …
WebPorosity. The capacity of a rock to transmit fluids is: Permeability. The saturated zone is: The zone where all pores are filled with water. An aquifer is: A body of saturated rock or sediment through which water can move easily. Which rock would most likely form an aquifer? Sandstone. WebThis study addresses the primary and secondary bioreceptivity of schist used as a support for prehistoric rock art in the C ôa V alley A rchaeological P ark (north‐east P ortugal) and provides ... Weathered schist was more bioreceptive than unweathered schist, associated with increased open porosity, ...
Schist is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture reflects a high content of platy minerals, such as micas, … See more The word schist is derived ultimately from the Greek word σχίζειν (schízein), meaning "to split", which refers to the ease with which schists can be split along the plane in which the platy minerals lie. See more Schistosity is developed at elevated temperature when the rock is more strongly compressed in one direction than in other directions (nonhydrostatic stress). Nonhydrostatic stress is characteristic of regional metamorphism where mountain building is taking … See more • Blueschist – Type of metavolcanic rock • Greenschist – Metamorphic rocks • List of rock textures – List of rock textural and morphological terms See more Geologists define schist as medium-grained metamorphic rock that shows well-developed schistosity.

WebPorosity and permeability are related properties of any rock or loose sediment. Both are related to the number, size, and connections of openings in the rock. More specifically, porosity of a rock is a measure of its ability to hold a fluid. Mathematically, it is the open space in a rock divided by the total rock volume (solid and space).
