- Majorite is named after Alan Major, who synthesized this particular type of garnet at pressures of more than 6 GPa at the Australian National University in the late 1960s (Ringwood and Major, 1971).

Majorite is a mineral found in the mantle of the Earth. Its chemical formula is Mg 3 (MgSi) (SiO 4) 3. It is a type of garnet, distinguished from other garnets in having silicon in octahedral as well as tetrahedral coordination.

Majority is a noun that in general means “the greater part or number; the number larger than half the total.” However, in terms of voting and elections, majority is defined as “a number of voters or votes, jurors, or others in agreement, constituting more than half of the total number.” It also refers to the party or group with the majorityvote. Fo...
Plurality is a noun that, like majority, can mean more than half of the whole. However when it comes to voting, plurality refers to “the excess of votes received by the leading candidate, in an election in which there are three or more candidates, over those received by the next candidate.” This means that someone who wins the plurality of votes re...
Majority and plurality voting are two legitimate types of elections under a democracy. In the United States legislative elections, candidates generally only need a plurality and not majorityto win (but not always—we see you, Georgia, Louisiana). But for the presidential election, both the plurality and majority of votes are involved. That’s because...

Majorite is believed to be an abundant mineral in the lower transition zone and uppermost lower mantle of the Earth at depths of 550–900 km (340–560 mi). It forms complex solid solutions with other Al, Fe, and Ca-bearing garnets in this region.
Majorite is a phase in the mantle that is related to garnet. Majorite is named after Alan Major, who synthesized this particular type of garnet at pressures of more than 6 GPa at the Australian National University in the late 1960s (Ringwood and Major, 1971).
Majorite is a type of mineral found in the upper mantle of the Earth. Its chemical formula is Mg 3 (Fe,Al,Si) 2 (SiO 4) 3. Majorite was first described from the Coorara Meterorite of Western Australia and has been reprted from various other meteorites.
Majorite normally occurs only at a depth of several hundred kilometres under very high pressures and temperatures. The Bonn researchers have now succeeded in demonstrating that, under these conditions, the mineral stores oxygen and performs an important function as an oxygen reservoir.
