Is Fayalite magnetic?
Yes, fayalite is a magnetic mineral because it contains iron atoms in its structure, which can exhibit magnetic properties. Fayalite is a member of the olivine mineral group and has a strong magnetic response due to the iron content.
What is density of olivine?
The density of olivine ranges from 3.2 to 4.4 g/cm3, depending on its composition and structure.
Does olivine rock form to become soil?
Yes, olivine rock can weather and break down over time to form olivine-rich soils. The weathering process involves the physical and chemical breakdown of the olivine mineral, eventually leading to the release of nutrients that can support plant growth.
Which mineral is present in much greater quantities in peridotite than gabbro?
Olivine is the mineral present in much greater quantities in peridotite than gabbro. Peridotite is rich in olivine, while gabbro contains less olivine and more plagioclase feldspar.
Is olivine more stable and weathering faster than quartz?
Following Goldich Dissolution Series (Or going backwards by Bowen's Reaction Series), olivine weathers before Quartz. Quartz has a framework silicate structure and olivine has a isolated silicate structure.
