Find out which role of the earth to bring down if you need to take the air away with adamant on the soles of your shoes .
Some of you out there are tired of your berth chore . Some want a diamond on their finger without having to contribute to political strife . Others just refuse to give a single penny to the creators of those godawful , cloying jewellery commercials . Whatever the intellect , digging for diamond just induce a bit easier . This new single-valued function was made by a team of research worker led by Trond Torsvik at the University of Oslo . Torsvik ’s squad based the function on scientific knowledge of how diamonds are made and how they move , which shows the spots most likely to shine .
Diamonds are made of the same stuff as pencil lead - – carbon paper . The difference between what ’s score up the Sudoku puzzle in the daily composition and what ’s flashing on an date ring is the social system of the carbon . It ’s vigor and pressure that induce a diamond ’s structure to forge . In fact , by applying pressure of about 700,000 pound per substantial in and warmth ( in the strain of electrical energy ) to pencil leading , companies can manufacture diamonds . The terra firma does the same thing . This process happens at a larger scale , but is a lot less sure . Carbon has to be buried about a hundred sea mile into the globe ’s mantle , and being exposed to 1100 - 1400 degree temperatures to make born infield .
The earth being what it is ( big ) there should be diamonds everywhere . One of the intellect diamond are n’t available at the dollar store is the fact that even when they are forge , they ’re a hundred mi down into the earth . They have to in reach to be any use .
A hundred miles of dig into thousand - degree temperatures is not a viable selection , so generally humans have to hold back until diamond come to them . They ’re pushed up , along with everything around them , by ‘ magma plumes , ’ which set forth at 1800 mile below the surface . Magma bubbles up from the boundary between the earth ’s core and its cape , lifting everything above it . Because plumes stay in place for millions of years , what ’s above them run to interchange over time . As the tectonic plates move over a feather , it pushes a part of them up , like a needle pushes through cloth as it moves through a sewing machine . This unexampled map of diamond - plentiful sites assume into accounting the steady position of magma plumes , while estimate the movement of tectonic plates for the last million old age .
The diamonds are still quite a ways down ( and likely to be on someone else ’s land ) but if there is a site in your backyard , congratulations !
