Magnetite has been important in understanding the conditions under which rocks form. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control oxygen fugacity. Commonly, igneous rocks contain solid solutions of both titanomagnetite and hemoilmenite or titanohematite.
Definition of relief well. : a vertical drain used for the drainage of a deep pervious stratum to relieve waterlogging of the surface soil.
The well should be capped to prevent surface water from entering the well. Submersible pumps, located near the bottom of the well, are most commonly used in drilled wells. Wells with a shallow water table may feature a jet pump located inside the home.
