Gneiss
Metamorphic rock that forms under intense pressure and high temperature and that is made of quartz, feldspar, amphibole and mica. Gneiss represents the highest grade of metamorphic rock, which is characterized by alternating bands of dark and light-colored minerals, foliation (i.e., parallel alignment of planar minerals) and tight folding. This rock type is common at mid to deep levels of continental crust.
Geothermal Glossary
Word of the Week – Adularia
Adularia Hydrothermal potassium bearing feldspar that forms in volcanic hosted geothermal reservoirs and is a favorable indicator of boiling and permeable conditions.
Word of the Week – Aquifer
Aquifer Porous and permeable rock unit or unconsolidated layer in the subsurface in which all the pores and voids are filled with water. Water supply for wells comes from aquifers.
Word of the Week – Basalt
