  • Word of the Week – Stable Isotopes

    Word of the Week – Stable Isotopes

    Stable Isotopes Refers to non-radioactive isotopes of elements, including those of oxygen, hydrogen, carbon, sulfur, and nitrogen. In geothermal geochemistry, the stable isotope ratios of oxygen (18O/16O) and hydrogen (2H/1H) in thermal waters are used to trace its origin (e.g., meteoric, magmatic). Read More »

    Did You Know … there is a mystical reason to travel to Monroe, Utah

      Did you know… there is a mystical reason to travel to Monroe, Utah – the Mystic Hot Springs! The Mystic Hot Springs are naturally occurring geothermal pools in Central Utah, about a three hour drive south from Salt Lake City. They have been used ever since the Indigenous People, including the Ute, Piute and… Read More »

    Word of the Week – Lava Flow

    Lava Flow A product of an erupting volcanic cone or fissure made up of liquid molten rock that flows downhill and eventually solidifies due to cooling. Read More »
  • Word of the Week – Transcurrent Fault (Strike-Slip Fault)

    Word of the Week – Transcurrent Fault (Strike-Slip Fault)

    Transcurrent Fault (Strike-Slip Fault) Vertically dipping fault that results from horizontal shear stress. Slip movement during an earthquake is sideways rather than up or down. Read More »
  • Word of the Week – Normal Fault

    Word of the Week – Normal Fault

    Normal Fault High angle fault that results from extensional stress and forms a steeply dipping planar structure. Slip movement during an earthquake is vertical and down dip. The down-dropped block is called the hanging wall and the uplifted block is called the footwall. Read More »

    Did You Know that renewable energy corridors can be the future of energy production?

    Did You Know… Renewable Energy Corridors Can Be the Future of Energy Production? In the Escalante desert of southwestern Utah, near the town of Milford, there are four different types of renewable energy: wind, solar, biogas, and geothermal. They’re all being used to produce energy at the same time. The co-location and concentration of such… Read More »
  • Word of the Week – Zircon

    Word of the Week – Zircon

    Zircon Zirconium silicate (ZrSiO4) is a minor or accessory mineral in igneous and metamorphic rocks. It contains measurable albeit minor amounts of uranium and lead, which make it amenable for radiometric dating. Zircons are some of the oldest dated minerals on Earth. Read More »
  • Word of the Week – Diorite

    Word of the Week – Diorite

  • Word of the Week – Granite

    Word of the Week – Granite

    Granite Light colored, coarse grained, intrusive rock with a felsic (silica-rich) composition that is mostly made of quartz, sodium and potassium-bearing feldspar, and plagioclase.
