Exempel på hur man kan använda PYROXENITES i en mening

• It typically occurs as an alteration product at the contact between felsic and mafic or ultramafic rocks such as pyroxenites and dunites.
• Pyroxenites are classified into clinopyroxenites, orthopyroxenites, and the websterites which contain both types of pyroxenes (see diagram below).
• The mountain itself is mainly made up of amphibolite, pyroxenites and gabbro, and contains deposits of bauxite.
• 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.
• Some geologists think the boundary between pyroxenites and lherzolites, that is also found in outcrops in the Ivrea zone, represents the Mohorovičić discontinuity (the Moho).
• Minerals found associated with these rocks include: pyroxenites, amphibole, apatite, biotite, calcite, magnetite, monazite, nepheline, pyrite, pyrochlore, pyroxene and quartz.
• The hill range is mainly made up of charnockites, with some pyroxene granulites, granites, khondalites, pyroxenites and dolerites.
• In the Togo and Benin regions, the following rock types have been identified: metasandstones, schists, metasilexites, metasiltstones, metaconglomerates, metatillites, carbonate rocks or marbles, ultramafic rocks, metajaspillites, metahematites, quartzites, quartz schists, micaschists, gneisses, migmatites, amphibolites, granites, charnockites, eclogites, metabasalts, calc-silicate rocks and pyroxenites.
• The ultramafic xenoliths found are mostly spinel lherzolite, with the final 20% harzburgites, dunites, and pyroxenites.
• These granites, which are collectively called the Gold Butte Granite, intrude garnet-cordierite-sillimanite and hornblende gneisses, migmatites, and older granites, pyroxenites, and hornblendites.
• The Mocksville Complex consist of metamorphosed/unmetamorphosed gabbros, pyroxenites, hornblendites, wehrlites, granites, and diorites.
