tonalite การใช้

• A greater amount of plagioclase would designate the rock as tonalite.
• The Federal Golf Course Tonalite introduces some veins and saccharoidal galena.
• These basalts were intruded by a tonalite pluton shortly after their eruption.
• In older references tonalite is sometimes used as a synonym for quartz diorite.
• This intrusion is known as Federal Golf Course Tonalite.
• Most of the mineral deposits are close to the tonalite-schist contact.
• They are like rocks called TTG ( Tonalite-Trondhjemite-Granodiorite ).
• The mountain made of Cretaceous Orthogneiss, and Tonalite.
• Minerals in the tonalite are quartz, plagioclase, alkali feldspar and hornblende.
• Granodiorite, tonalite and diorite are most common intrusive rocks found in continental arcs.
• These are characterised by soils varying from thick peat to bare granite and tonalite.
• The predominate rock type is a white, coarse-grained, foliated hornblende tonalite.
• It is paved with tonalite plates.
• Likewise, partial melting of eclogite has been modeled to produce tonalite-trondhjemite-granodiorite melts.
• The older one consists of granodiorite and adamellite with inclusions of tonalite, diorite, and gabbro.
• Migmatised igneous or lower-geochemical signatures and typically plagioclase dominant mineralogy forming monzonite, tonalite and granodiorite compositions.
• The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite.
• When a granitoid contains less than 10 % orthoclase, it is called tonalite; pyroxene and amphibole are common in tonalite.
• When a granitoid contains less than 10 % orthoclase, it is called tonalite; pyroxene and amphibole are common in tonalite.
• The schematic image above right shows two possible flat subduction mechanisms that could create the tonalite plutons seen in the greenstone belt.
