| 21. | Basalt is generally created as a partial melt of peridotite at 20 120 km depth.
|
| 22. | Many peridotite occurrences have characteristic textures.
|
| 23. | Peridotite nodules with irregular equigranular textures are often found in alkaline basalts and in kimberlite pipes.
|
| 24. | It consists of one to three meter thick pegmatitic peridotite and troctolite with disseminated sulfide minerals.
|
| 25. | The variety of peridotite is lherzolite.
|
| 26. | Puyehue was characterized by eruption of basaltic andesites to dacites until its activity turned mantle peridotite.
|
| 27. | It is predominantly made of peridotite.
|
| 28. | Peridotite xenoliths originate from of depth.
|
| 29. | The garnets from mantle-derived rocks, peridotites, and eclogites commonly contain a pyrope variety.
|
| 30. | Magnesium-rich olivine forms a large proportion of peridotite, and so magnesium content is high.
