Composition of pyroxenes in hornblendites from the Northern part of the Ditro syenite massif
Pyroxene is an essential mineral of olivine-pyroxene hornblendites and plagioclase-pyroxene hornblendites cropping out in the northern part of the Ditro syenite massif. On the basis of microprobe analyses and the IMA classification (Morimoto, 1988; Rock, 1990), Ferroan Diopsides arc the most importa...

| Tartalmi kivonat: | Pyroxene is an essential mineral of olivine-pyroxene hornblendites and plagioclase-pyroxene hornblendites cropping out in the northern part of the Ditro syenite massif. On the basis of microprobe analyses and the IMA classification (Morimoto, 1988; Rock, 1990), Ferroan Diopsides arc the most important pyroxenes of the ultrabasic rocks. As alteration products, subsilicic aluminian sodian [Magnesium-rich] Augites and/or subcalcic magnesium-rich Augites can be found in a subordinate amount. Subsilicic aluminian Aluminian AegirineAugite can also appear in the marginal parts of the single Ferroan Diopside grains. |
