Current methods of exploration in geophysics are very
expensive, extremely tedious and moreover
the results are often unreliable.
Our idea hopes to overcome these restrictions
and provide for easy identification of ores.
When high energy electrons are incident on a metal or ore
they lead to the generation of a
continuous X-ray spectrum.
So why did this happen?
It occurs due to the knocking off of an electron
in a lower shell, leading to an electron transition
accompanied by the emission of a photon.
the photons produced in the form of X-rays
give a spectrum characteristic to each element.
Say this is the spectrum of Aluminium
and this of Bauxite.
Then by comparing the two,
we can identify Bauxite as an ore of Aluminium
So this can be used in mines to find the composition of different ores.
Thank you CERN !!
