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.
An aquifer is a layer of water in the soil. A well is a hole drilled into that soil that will permit water to fill the lower levels of that hole. Water is then pumped from the â¦ well. A pump connected to a metal pipe is lowered to the bottom of the well. The pump is generally operated by a motor located at the surface. The pump forces water from the aquifer up the pipe and to the distribution point at the surface.
