undersaturated การใช้

• Nephelinite is an example of a silica-undersaturated igneous rock.
• Melilite also occurs in unusual silica-undersaturated igneous rocks.
• At certain depths water is undersaturated in calcium carbonate but saturated in dolomite.
• They do not include silica-undersaturated, alkalic, or peralkaline rocks.
• In areas of up welling this undersaturated water is brought to the surface.
• A normative feldspathoid classifies a rock as silica-undersaturated; an example is nephelinite.
• Carbonate minerals are supersaturated in the surface ocean but are undersaturated in the deep ocean.
• Metasomatism has also been considered critical for enriching source regions of some silica-undersaturated magmas.
• Nepheline syenites are silica-undersaturated and some are peralkaline ( terms discussed in igneous rock ).
• It is associated with other minerals typical of undersaturated environments, namely leucite, cancrinite and natrolite.
• Rocks with feldspathoids are silica-undersaturated, because feldspathoids cannot coexist in a stable association with quartz.
• A mineral is undersaturated if its saturation index is negative, indicating that it is favored to dissolve.
• Nayar's solution to over-or undersaturated areas of light has two parts : hardware and software.
• Silica-undersaturated mafic igneous rocks contain magnesian olivine but not magnesian orthopyroxene, and / or a feldspathoid.
• If the magma contains less water that it could, it is " undersaturated " in water.
• This together with their silica-undersaturated composition supports inferences that carbonatites are formed by low degrees of partial melting.
• Silicate minerals associated with such compositions are pyroxene, olivine, and silica-undersaturated minerals such as nepheline and other feldspathoids.
• Seawater at the depth of the crater is undersaturated with respect to calcite and rapid burial would be needed to preserve those crystals.
• For this reason it is not advised to utilise a CIPW norm on kimberlites, lamproites, lamprophyres and some silica-undersaturated igneous rocks.
• Usually insufficient water and carbon dioxide exist in the deep crust and mantle, so magma is often " undersaturated " in these conditions.
