Connate fluids — The term connate fluids in the context of geology, and of sedimentology in particular, refers to the liquids that were trapped in the pores of sedimentary rocks as they were deposited. These liquids are largely composed of water, but also contain … Wikipedia
Sedimentary rock — Middle Triassic marginal marine sequence of siltstones (below) and limestones (above), Virgin Formation, southwestern Utah, USA Sedimentary rock are types of rock that are formed by the deposition of material at the Earth s surface and within… … Wikipedia
Porosity — or void fraction is a measure of the void (i.e., empty ) spaces in a material, and is a fraction of the volume of voids over the total volume, between 0–1, or as a percentage between 0–100%. The term is used in multiple fields including… … Wikipedia
Komatiite — Komatiites are ultramafic mantle derived volcanic rocks. They have low SiO2, low K2O, low Al2O3, and high to extremely high MgO. They were named for their type locality along the Komati River in South Africa. True komatiites are very rare and… … Wikipedia
Diagenesis — In geology and oceanography, diagenesis is any chemical, physical, or biological change undergone by a sediment after its initial deposition and during and after its lithification, exclusive of surface alteration (weathering) and metamorphism.… … Wikipedia
Lithification — (from the Greek word lithos meaning rock and the Latin derived suffix ific ) is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity… … Wikipedia
Scientific drilling — is a way to probe down into the Earth, allowing scientists and students to obtain samples of sediments, crust, and upper mantle. In addition to rock samples, drilling technology allows us to obtain samples of connate fluids and of the subsurface… … Wikipedia

Magmatic water — or juvenile water is water which exists within and in equilibrium with a magma or water rich volatile fluids which are derived from a magma. This magmatic water is released to the atmosphere during a volcanic eruption. Magmatic water may also be… … Wikipedia
Overpressure — The term Overpressure (Δp) is applied to a pressure difference, relative to a normal or ambient pressure, in various circumstances: In engineering: the pressure difference over the wall thickness of a pressure vessel. It is the overpressure, not… … Wikipedia
