Which mineral is present in much greater quanitites in peridotite than in gabbro?
Olivine is the mineral that is present in much greater quantities in peridotite compared to gabbro. Peridotite is rich in olivine, which gives it its characteristic green color, while gabbro contains less olivine and more dark minerals like pyroxene.
How does olivine form?
Ophiolites form when the ocean crust is young and buoyant. At this point, it is less dense than the continents and is pushed on the continental crust when tectonic action occurs. Ophiolites are a part of the oceanic crust and upper mantle that have been placed on a continent.
Does olivine rock form to become soil?
Sand is formed from the breakdown of rocks. If a rock contains large amounts of olivine, then when this rock weathers, olivine sand will be formed. There are beaches in New Zealand that are almost exclusively made of green olivine crystals.
This mineral is olive-green glassy and shell-like in fracture and is found in some meteorites?

What mineral group is peridot in?
