Explanation: An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation). So in the end you can say this fossil is 50 thousand years old (always with an associated uncertainty). We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision. Relative dating is like looking at a multi-layered cake. The base layer must come first, then the second and then the third. So I can say the second layer is younger than the first and older than the third but I have no idea whether the cake is 5 minutes or 5 million years old. Relative dating is used commonly when looking at the relative order of geological events. What can complicate relative dating is when the strata is not the right way up! Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!
Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.
<span>Platinum can be found in: Chromite bands
Chromite could be easily found in ultramafic layer of intrusive rocks and it contain several similar components as those that we could found in magma.
The black bands part of the chromite also carries several substance from platinum group metals.</span>
