hornblendite मीनिंग इन हिंदी

"' Hornblendite "'is a plutonic rock consisting mainly of the amphibole hornblende.
The Lherz massif also contains harzburgite and dunite, as well as layers of spinel pyroxenite, garnet pyroxenite, and hornblendite.
Hornblende-rich ultramafic rocks are rare and when hornblende is the dominant mineral phase they are classified as hornblendites with qualifiers such as garnet hornblendite identifying a second abundant contained mineral.
There are some curious instances of rocks having the same chemical composition, but consisting of entirely different minerals, e . g ., the hornblendite of Gran, in Norway, which contains only hornblende, has the same composition as some of the camptonites of the same locality that contain feldspar and hornblende of a different variety.
