Mineral Geothermometer
A secondary mineral phase whose stability is defined by a lower and sometimes an upper temperature threshold. Common mineral geothermometers comprise clays, zeolites and epidote, with crystal structures that contain a hydroxyl (OH–) or water (H2O) molecule. The temperature ranges of mineral geothermometers are calibrated from investigations of a large number of drilled geothermal resources where mineral zonations and temperature gradients have been determined.

Word of the Week – Magma
Magma Molten rock typically having a temperature between 800° and 1100° C (~1500-2000° F). Magma is the source of high-grade geothermal energy in conventional resources.
Word of the Week – Magnetotelluric (MT) Geophysical Method
Magnetotelluric (MT) Geophysical Method Makes use of naturally occurring electromagnetic waves to image the resistivity structure of the subsurface. The results can reveal the locations of hot geothermal fluids, blankets of clay alteration, and highly saline water. MT...
Word of the Week – Microseismicity
Microseismicity Tiny earthquakes that result from slip or shear along a fracture caused by an uneven distribution of stress. The displacements are very small scale and unfelt at the surface. They can only be detected with sensitive equipment such as geophones and...
