Definition of anorthosite in English:
A plutonic rock composed largely of calcic plagioclase.
- Because of the preponderance of the mineral anorthite (a calcium-rich variety of the mineral plagioclase feldspar) this rock type is called anorthosite.
- Coarse-grained anorthosite is the predominant rock type in these bodies.
- The plagioclase crystals would have formed subcircular lenses of anorthosite that punctuated background chromite accumulation.
