Exempel på hur man kan använda ANORTHOSITES i en mening

• It occurs as clear, white to gray, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites.
• Magmatism induced by continental rifting just prior to and in the Cambrian Period produced the granites and rhyolites (the red rocks), gabbroic rocks, anorthosites, and diabases (the black rocks).
• Ideally, the stratigraphic sequence of an ultramafic-mafic intrusive complex consists of ultramafic peridotites and pyroxenites with associated chromitite layers toward the base with more mafic norites, gabbros and anorthosites in the upper layers.
• Precambrian gneisses, anorthosites, charnockites, and amphibolites characterize the Schirmacher Hills and Wohlthat Mountains in central Queen Maud Land.
• Magmatism induced by continental rifting just prior to and in the Cambrian Period produced the granites and rhyolites (the red rocks), gabbroic rocks, anorthosites, and diabases (the black rocks).
• Identification, petrogenetic and tectonic characterization of a variety of rock types from the Archaean greenstone belts of southern India such as ultramafic komatiites, high-Mg basalts, anorthosites, boninites, adakites, Nb-rich basalts, grey-wakes, banded iron and manganese formations, the distinct phases and types of the TTG gneisses and granitoides;.
• Most of the samples obtained on the Apennine Front are KREEP (potassium, rare-earth elements, phosphorus) materials, anorthosites, recrystallized norite, or recrystallized breccia.
• Another line of research follows up on this, proposing that differences in the densities of newly formed crystals caused separation of crustal rocks; upper crust largely composed of fractionated gabbros and lower crust composed of anorthosites.
• Her dissertation was Rare earth element and other trace element microdistributions in two unusual extraterrestrial igneous systems: The enstatite achondrite (aubrite) meteorites and the lunar ferroan anorthosites.
• Studies conducted using feldspathic meteorites show that they do not contain ferroan anorthosites, KREEP components, or Mg-suite rocks, which further supports that the LMO theory was not global and that the lunar crust is heterogeneous.
