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.
A check valve prevents the higher pressure water from returning to the source when the pump is not operating. Now, this type of booster operates exactly like a domestic water well system except that, in this example, it is used to boost the existing pressure of some water source rather than drawing water from a well.
