Creation Moment 11/22/2021 - Creator's Building Block of "Davemaoite" Found for Heating Planet Core

 .....and the elements shall melt with fervent heat?
2 Peter 3:12
 
"Calcium silicate perovskite (CaSiO3) is arguably the most
geochemically important phase in the Earth’s lower mantle, because it concentrates elements that are incompatible in the upper mantle. 
 
No one has ever successfully retrieved this high-pressure compound from the lower mantle before. This is because CaSiO3-perovskite is ‘unquenchable,’ meaning that it cannot retain its structure after being removed from its high-pressure environment. In a new study, U.S. geologists have finally found the first calcium silicate perovskite from Earth’s lower mantle in a diamond from the Orapa kimberlite pipe in Botswana.
 
The crystalline compound the researchers found was named
davemaoite in honor of the prominent experimental high-pressure geophysicist Ho-kwang (Dave) Mao and confirmed as a new mineral by the Commission of New Minerals.
 
The structural and chemical analysis of davemaoite showed that it is able to host a wide variety of elements in its structure, including potassium, thorium and uranium — three of the major heat-producing elements. 
 
The findings support the existence of compositional heterogeneity within the lower mantle and, given the mineral’s overall abundance, suggest that davemaoite likely influences heat generation in the deep mantle." SciNews
