most likely Mg rich pyroxenen since Fe starts melting earlier from a melt and also mantle rocks that are highly melt depleted contain very high mg rich pyroxenes
What else can I help you with?
Which has a higher melting temperature magnesium rich pyroxene or iron rich pyroxene?
Iron-rich pyroxene generally has a higher melting temperature than magnesium-rich pyroxene due to the presence of iron ions, which increases the bonding strength between the pyroxene mineral components, requiring higher temperatures to break these bonds.
What compound has the higher melting temperature Strontium Sulfate or Magnesium Oxide?
Magnesium Oxide Strontium Sulphate has a melting point of 1606°C while Magnesium Oxide has a melting point of 2852°C
What element has the highest melting point out of lithium or magnesium?
Magnesium has a higher melting point.
Is magnesium sulphate's melting point above room temperature?
Magnesium sulfate doesn't melt; at high temperature MgSO4 is thermally decomposed.
Does magnesium oxide burn at a higher temperature than magnesium?
Magnesium oxide is non-flammable, but magnesium can burn. Magnesium oxide Melting Point: 2852 °C, 3125 K, 5166 °F Boiling Point: 3600 °C, 3873 K, 6512 °F Magnesium Melting Point: 923 K, 650 °C, 1202 °F Boiling Point: 1363 K, 1091 °C, 1994 °F
Which mineral pyroxene or orthoclase crystallizes from magma first?
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
Why magnesium has a higher melting point?
a more dense metal
What Affects the melting temperature of magma?
The composition of the magma plays a significant role in determining its melting temperature. Magma with higher silica content tends to have a higher melting temperature. Pressure also affects the melting temperature; higher pressure usually results in a higher melting temperature. Water content can lower the melting temperature of magma by acting as a flux, allowing minerals to melt at lower temperatures.
Which substance sodium oxide or magnesium oxide has higher melting point?
sodium oxide: 1132oC magnesium oxide: 2852oC
Is the temperature of the outer core higher or lower then the melting point?
higher
What is the relation between melting temperature and GC content in DNA?
Higher GC content in DNA is associated with a higher melting temperature, as GC base pairs have three hydrogen bonds compared to two in AT base pairs, making them more stable. Therefore, DNA sequences with higher GC content require higher temperatures to denature during melting compared to sequences with lower GC content.
Is the temperature of the inner core higher or lower than its melting pointing?
higher
